Introduction

With the rapid development of global big data and the geometric progression expansion of network information resources, the information 3.0 environment with internet information as the information carrier brings a new challenge to the information service work -- serious information overload. Intelligence workers can not rely on manpower to sort out and analyze information from massive information, or even rely on manpower alone to locate the object of intelligence analysis. Therefore, Internet intelligence tools have become the working basis of intelligence agencies. With the rise of artificial intelligence, intelligence agencies use intelligent analysis tools to carry out intelligence analysis work has become a reality.

Information definition and information period division

1.1 information definition

Intelligence is a valuable judgment made by the human brain.

The first key word of intelligence definition is "human brain". Intelligence is neither the conditioned reflection without thinking, nor the material without thinking and processing by human brain, such as information and photos.

The second key word is "valuable.". The "valuable" of intelligence is aimed at the value of specific target objects, regardless of whether it is valuable to others, which reflects the pertinence of intelligence objects.

The third key word is "judgment". "Judgment" is not only a verb of process, but also a noun of result; "judgment" not only constitutes the process of information production, but also represents the result of information production, that is, the result of judgment knowledge.

Information production generally goes through four processes: information collection, information storage, processing, analysis and release. The "analysis" process takes judgment as the core, so it is also the core of information work.

The process of information generating knowledge is the expression of another dimension of learning, research, invention and creation. Information science can be defined as the science that studies how the human brain makes valuable judgments. It is not only the science of obtaining (judging) knowledge from the unknown, but also the science of how to acquire new knowledge, and the science of human innovation process and innovation itself. From a philosophical point of view, information science is a science that studies human beings' exploration of the unknown, the process of exploring the unknown and innovation.

1.2 description of definition

1.2.1 define "information" and "intelligence". According to "intelligence is a valuable judgment made by human brain", this paper defines the information without human intelligence judgment as "information", and defines the interpretation result (knowledge) obtained by human intelligence judgment as "intelligence".

1.2.2 define "research and judgment" and "interpretation". This paper defines the process of human intelligence transforming information into knowledge as two stages - "research and judgment" and "interpretation".

Among them, "study and judgment" is defined as the orientation of judgment direction and the selection of important information, which is the process of judging information direction and selecting important information for interpretation; "interpretation" is defined as the process of analyzing important information, so as to discover the nature of things, the laws behind them, the possible new situation, the benefits and losses under the new situation, and then formulate countermeasures.

Interpretation is a term originally used in image information work, also known as interpretation and interpretation. It originally refers to people's use of various technologies and means to identify photos and images by analyzing the features of ground object images, so as to obtain information, such as the interpretation of reconnaissance satellite photos. In this paper, the definition of interpretation is different from its original concept, especially the process of processing information into valuable information and countermeasures by studying the laws, changes or influences contained in existing information.

1.3 information period division

Information itself does not change with the change of research objects and the development of science and technology, especially information technology. Therefore, the attributes of intelligence, such as knowledge and transmissibility, will not be changed, and the intelligence processing ideas based on intelligence itself will not be changed. However, the carrier of information, carrier based processing tools and carrier related information processing and methods, ideas and means will change.

According to the changes of these elements of information work, information work can be divided into different stages of development, and a domestic information stage can be divided into:

Intelligence 1.0: from literature transmission to information service (1956-1978), it is mainly interpersonal intelligence, supplemented by paper information.

Intelligence 2.0: from information service to knowledge service (1979-2012), paper-based information is dominant, and the transition to Internet intelligence is relatively ignored.

Intelligence 3.0: from knowledge service to intelligent service (from 2013 to now), artificial intelligence processing technology and tools based on Internet information have developed rapidly, paper information has gradually disappeared, and interpersonal intelligence has returned to its proper position; the combination of Internet intelligence and artificial intelligence represented by artificial intelligence has become a new direction.

The division of information historical stage is a complicated process, which is influenced by the state, science and technology, especially the development level of information technology, politics, society, economy and other factors.

By analyzing the differences of CIA's policies and institutions in different periods, this paper finds that the CIA's intelligence stage is different from the domestic intelligence development stage, which can be divided into the following three periods, about 10 years ahead of the development of China's science and Technology Intelligence:

Intelligence 1.0: before and in the early postwar period

Intelligence 2.0: 1970s to the end of the 20th century

Intelligence 3.0: from the beginning of the 21st century to now

According to the information production process, intelligence personnel obtain information through information carriers, first study the research direction and important landmark information, and then read the information to get knowledge.

In different information periods, information carriers, characteristics of research and judgment, information tasks and other information production factors have their own characteristics. The specific performance is as follows: information carrier changes from concrete to abstract; information workers in the process of information production change from difficult to easy, judgment from easy to difficult, data reading from relatively simple to major difficulties, and judgment focus develops from simple judgment to complex judgment or even comprehensive complex re judgment; The task of intelligence agencies has changed from acquiring information by force to processing information intelligently.

2.1 transformation of information carrier from concrete to abstract

2.1.1 intelligence 1.0:

In the era of human or material intelligence 1.0, human intelligence (hu-m int) is the main information carrier. Human intelligence sources include various means to collect foreign trends, with the focus on people and their channels to obtain valuable information.

In the era of intelligence 1.0, intelligence mostly exists in the brain of specific personnel, on paper files or other articles recording intelligence, as well as in safes or other containers storing intelligence. The carrier of information is based on people or specific goods. Information is obtained by daggers, master keys, thieves, secret agents and enemy defectors.

2.1.2 intelligence 2.0:

Information carrier is from literature information to Internet information. In the era of information 2.0 (literature information era), information mainly comes from open source information. Open source information refers to the published materials available to the public - newspapers, books and periodicals, so it is sometimes called literature intelligence (lit int).

In the era of intelligence 2.0, intelligence is mainly from "hard copy" sources. Information from open sources is not obtained through the network, but from traditional publications.

In the era of information 2, books and documents are the sources of information, and newspapers, books and periodicals are the main carriers of information. Information workers spend money to buy information and obtain information. The main information tools are scissors and paste. More possession of materials, reading materials, association problems and interpretation information means more access to information.

Since the era of intelligence 2.0, information mainly comes from open source information. Interpersonal intelligence is still suitable for providing information that cannot be obtained by other means and plays an important role in it. However, the dominant position of interpersonal intelligence has been replaced by open source intelligence in many intelligence fields, which has declined to a certain extent compared with the era of intelligence 1.0.

There are two main reasons for the decline of interpersonal intelligence:

First, with the development of human civilization, most of the intelligence agencies and staff reduce their access to competitor information through interpersonal intelligence due to cost, moral and legal constraints. Even if not all enterprises are limited by moral factors, the vast majority of enterprises will not choose the source of interpersonal information, because once the use of interpersonal information is exposed, it will cause huge reputation and economic losses to enterprises.

For example, in 2001, P & G collected the non-public information of Unilever through interpersonal intelligence. After the event was exposed, P & G made an indemnity of US $10 million to Unilever, which was only a small part of the solution to the event, and the reputation loss was immeasurable.

Secondly, the intelligence community has proved that more than 80% of information can be obtained through open channels. Compared with interpersonal information, open information is not only less difficult to obtain, but also has a strong value of analysis and research in various fields.

2.1.3 intelligence 3.0: the information carrier is the Internet

At present, the content of public information is far more than that of all periods in history. Under the environment of intelligence 2.0, most of the open source information is printed into volumes, while the most commonly used open source information of intelligence 3.0 is Internet information. Human activities are recorded in large quantities, and the Internet has become the largest, most complete and fastest database.

Thanks to the rapid development of global big data and the rapid expansion of network information, intelligence personnel can easily access a large number of open information that was previously unavailable, such as:

① A large number of images obtained by commercial imaging satellites;

② A large number of economic data contained in the business database;

③ Disclosure of non-public data resources. For example, data resources that have not been disclosed by enterprises or stored locally by individuals in the past are uploaded or disseminated in the form of music, photos, videos, voice-controlled videos, etc. in the era of intelligence 3.0;

④ Click data of mobile Internet terminals, such as financial transactions, browsing history, etc;

⑤ Data flow of personal travel and daily behavior generated by electronic map;

⑥ Personal social behavior data and information transmission on social media;

⑦ E-commerce forms online transaction data such as personal purchase list, payment data, click sorting, evaluation behavior, etc;

⑧ Search engine keeps the data of users' search behavior and questioning behavior.

...

In the era of intelligence 3.0, online open information becomes the main carrier of intelligence, and network becomes the best starting point of intelligence analysis. Internet, as the largest open source data repository, covers almost all the topics of interest to intelligence agencies. Interpersonal information and library information are still the objects of information analysis, but most of the information comes from the Internet.

The evolution of information carrier needs the synchronous development of information tools. Scissor glue or copy and paste in the era of intelligence 2.0 can't meet the needs of information processing in intelligence 3.0. In the era of intelligence 3.0, more powerful tools are needed to use artificial intelligence to process various and huge amounts of information on the Internet. Intelligent Internet intelligence + interpersonal intelligence will be a new trend.

2.2 transformation of intelligence judgment from focusing on interpretation to focusing on research and judgment

According to the information production process, intelligence workers need to collect information, then sort out the direction, and then make a judgment. In different periods, the workload and emphasis of intelligence workers' judgment are different. Information workers' collection of information in the process of information production changes from difficult to easy, and judgment changes from easy to difficult, and the emphasis of intelligence workers' judgment changes from simple interpretation to comprehensive complex information interpretation and countermeasure research.

2.2.1 intelligence 1.0: the difficulty is information collection, and judgment is relatively easy in the era of intelligence 1.0. The main work of interpersonal intelligence is to collect information, and the main difficulty is to cultivate and contact agents, seize and steal information.

The value of interpersonal intelligence depends more on information collection than judgment and analysis. Once most of the information is obtained, it is less difficult to judge the information.

On the one hand, the information source and purpose are very clear, so it is easy to study and judge.

On the other hand, because intelligence is mostly the expression of the real will of opponents, it is easy to read.

Intelligence 1.0 era is the era of interpersonal intelligence. The key of intelligence is information collection, that is, agents collect information and intelligence. For example, the United States attaches great importance to the protection of intelligence sources - agents, and the degree of protection of information collected by agents clearly shows the protection of intelligence sources - agents.

In December 1941, the United States formally declared war on Japan. During the whole world War II, the office of strategic services (OSS) has never been able to fight for the right to use the original information collected by intelligence agents.

After the war, when the Central Intelligence Group (CIG) was established, the information analysts could not use the information either. Until 1948, some authorized analysts had the right to read the signal information regularly. The protection of information by the United States in the era of intelligence 1.0 shows the importance of information collection and protection.

2.2.2 intelligence 2.0: Intelligence judgment is as important as information acquisition

In the era of intelligence 2.0, the source of intelligence is not clear in the era of 1.0, and the specific information in which magazine and article is not clear, which needs to be determined through research. At the same time, it is necessary for intelligence personnel to judge the conclusion by reading the connection behind the acquisition of literature information, and a large number of reading has become the basic work of intelligence analysis and judgment.

For example, some documents need information analysts with rich knowledge and strong professional knowledge to integrate and refine the different knowledge points in the documents; especially some information that needs to be obtained by detour requires information analysts to interpret the information in a large amount.

In the era of information 2.0, the content of information needs professional background knowledge to understand, so Mr. Qian Xuesen put forward the concept of comprehensive research hall.

In the 1970s, the intelligence collection guidance staff was established by the Intelligence Department of the CIA, which was responsible for issuing the collection requirements of decision makers and intelligence analysts to intelligence collectors.

At the same time, the intelligence department, in the name of the unit, employs external experts to communicate and guide with intelligence personnel on a regular basis, and requires intelligence analysts to actively contact with external experts, so as to enhance the analysis ability and creativity of intelligence analysts.

The establishment of CIA "collection and guidance center" shows that the location of intelligence sources in the era of intelligence 2.0 is not clear in the era of intelligence 1.0, and the required information needs to be determined by the judgment of intelligence analysts.

The regular exchange of external experts indicates that information can not be obtained through simple interpretation of information in this period. Information work requires information analysts with rich knowledge and strong professional knowledge to interpret information.

Since the era of intelligence 2.0, the requirements of intelligence work for the ability of intelligence workers have developed from "thief" to "T-type talents" - both with high professional level and broad cross domain knowledge.

The requirements of this information industry for the ability of information workers continue to this day. Mr. Qian Xuesen's idea of the comprehensive seminar hall has become the basic guideline for the process of information research and interpretation across the information 2.0 and 3.0 times. As a result, the intelligence community has introduced the system science, especially the thought, theory and method of system engineering. The information science has entered the era of team operation from the era of individual hero.

2.2.3 intelligence 3.0: intelligence research and judgment has become the core and the biggest difficulty of intelligence work. Information collection based on the Internet has become a general technology, and artificial intelligence has become a benchmark in the new era.

In the era of intelligence 3.0, commercial browsers and search engines make it relatively easy for intelligence personnel to obtain information. What follows is that intelligence workers face too much information, it is difficult to screen valuable information, and even difficult to locate information. Studying and judging valuable information has become the main work of intelligence judgment.

Internet as a source of information brings two challenges to information research and judgment:

One is the huge amount of information on the Internet. Intelligence workers inevitably encounter information overload and information dimension disaster. They cannot use all information and filter valuable information from a large number of data.

Second, the quality of Internet information varies greatly, some of which are misleading or even completely wrong.

In the era of intelligence 3.0, intelligence personnel need to quickly locate the information source and judge which information is valuable, that is, study and judge, then interpret the information, and then get intelligence. Intelligence personnel should study and judge information quickly from a large amount of information, and solve the huge difference between the ability of interpretation and the information that needs to be interpreted.

2.3 the main task of the intelligence agency is from information collection to information intelligent processing

2.3.1 intelligence 1.0: intelligence agencies gather information collection

In the era of Information 1.0, the main workload of information work is to collect information and judge the workload is small. The main tasks of intelligence agencies are to build and develop information collection departments, strictly protect information sources, and enhance information collection and management capabilities.

Figure 1 organization chart of CIA intelligence department in 1952

Taking the organizational structure and management principles of the CIA as an example, this paper analyzes the main tasks of the intelligence work of the intelligence agencies in various periods (see Figure 1). The organization and management of the CIA in the era of intelligence 1.0 has the following characteristics.

① In 1952, the CIA's "direct of intelligence (DI)" and "the direct of plans (DP)" were affiliated with the CIA. The intelligence agents in the "planning department" are responsible for collecting secret information. The "planning department" is not only isolated from the "intelligence department", but also has a higher status than the "intelligence department".

② The "Office of collec tion and distribution" within the intelligence department is also responsible for collecting information, and its position is superior to other subordinate agencies of the intelligence department.

In the era of intelligence 1.0, the judgment workload of intelligence work is relatively small. The main task of intelligence agencies is to strengthen the functions of intelligence collection departments. The management mode and organizational structure of CIA in this historical period also have this feature, which is embodied in:

① The complete independence of "planning department" and "intelligence department" indicates that what kind of information "planning department" collects is not under the guidance of "intelligence department". At this time, the CIA has no specialized agency engaged in information research and judgment, indicating that the workload of information research and judgment is small.

② The "planning department" responsible for collecting information is higher than the "intelligence department" responsible for judging information; the "collection and Distribution Department" is superior to other subordinate agencies of the intelligence department; In order to protect the sources of information collection, the CIA implemented closed management on the "planning department", which showed the importance of information collection under the intelligence 1.0 environment. The task of the intelligence agency is to build and develop the information collection department.

2.3.2 intelligence 2.0: integration of intelligence organization chart, situation and file

In the era of information 2.0, the way of information collection of information institutions has changed from the establishment of secret operation departments to the establishment of libraries and reference rooms to occupy information resources by purchasing materials. Because the carrier of information is paper books and materials, the theoretical methods of library science have become the application basis of information work.

At the same time, due to the increase of professional content, intelligence agencies attach great importance to training and investigating the professional knowledge, analysis ability, knowledge integration and refining ability of intelligence personnel, that is, the T-shaped talent ability mentioned above.

Information collection and information judgment are the main tasks in the era of information 2.0. During this period, the main source of information changed from interpersonal intelligence to open source intelligence. Intelligence agencies can purchase most of the information. The main task of intelligence work is to interpret a large number of information. The challenges faced by intelligence agencies changed from collecting information to paying equal attention to collecting and interpreting information.

In this context, the library, information and archives workers often work together, that is to say, "the picture, the situation and the archives are one" refers to the era of information 2.0 in fact, which is not the case in other information periods.

Figure 2 shows the organization chart of the CIA intelligence department in 1975. During this period, the organization and management of the CIA had the following characteristics.

① "The central reference service" replaces the former "Office of collection and dis segmentation" and "the central reference service" plays the role of a library as an information collection department. It can be seen from the structure of the intelligence department that the position of the "central information service" is parallel to that of other departments, and the position of the information collection department is no longer superior to that of other subordinate agencies of the intelligence department.

② After the 1970s, in addition to the establishment of the "intelligence collection guidance staff" as mentioned above and the arrangement of regular exchanges between experts and intelligence personnel, the CIA intelligence department established the "product evaluation staff (PES)" in 1982 ”The evaluation of information quality determines the promotion of information workers, and the quality of information analysis begins to be linked with the interests of information workers.

③ The information department divides the organizational structure according to different research directions, focusing on the deepening of professional knowledge of analysts. The interdisciplinary groups set up in some research divisions focus on a wide range of knowledge of intelligence personnel.

④ In the early 1980s, with the emergence of information technology, information concentration began to break away from the limitations of the library. In 1986, the U.S. Central Intelligence Agency set up "safe" to concentrate information sources, and proposed that "if it is not on our network, it does not exist, if it exists, it should be on our network".

This is one of the sources of Internet intelligence. The CIA's policies and concepts in this historical period are consistent with the main tasks of intelligence agencies in the era of intelligence 2.0:

① Compared with the "planning department" in the era of intelligence 1.0, the position of "intelligence department" is higher. In the era of intelligence 2.0, the CIA establishes "collection guidance center" to guide and plan the direction of information collection, which indicates that in the era of intelligence 2.0, the function of information collection is no longer superior to that of information research and judgment. The change of CIA's organization structure is no longer the most important task in the era of intelligence 2.0, but the main task is to collect and judge.

② The cultivation of intelligence personnel and the establishment of "product evaluation group" by the CIA in this historical period indicate that information interpretation has become the main task of intelligence work in this period. Intelligence agencies need T-type intelligence personnel and attach importance to the cultivation and investigation of their professional knowledge and the ability to integrate and refine their knowledge.

③ Although the CIA began to use the Internet to gather information resources in the 1980s, the idea of the CIA is still to occupy as much public information as possible. Although the carrier of information has changed from "library" to "Internet", a large number of online resources have not been formed yet. It is still the main task of the intelligence agencies to try to occupy information resources in an all-round way.

2.3.3 intelligence 3.0: intelligence agencies establish intelligent information processing tools

In the era of information 3.0, the feature of information work is that it is easy to collect information, and the main task is to deal with the problem of information overload in the Internet era, that is, it is not easy to select information with high value density, and information research and judgment becomes a bottleneck. In contrast to the extreme lack of information in the era of Information 1.0, the problem of information overload appears in the era of information 3.0. Intelligence personnel need to identify information with high value density in the mass information swamp.

Under the environment of intelligence 3.0, the focus of intelligence work is to deal with the information in the Internet era, and turn the massive Internet information that has not been processed by human brain into the small data and the statistical data intelligence that can be read and analyzed by human beings. Therefore, intelligence agencies must establish a batch of intelligent (AI) tools to deal with internet information.

In 2000, the assistant director of the CIA, Alan, pointed out that the difficulty of the intelligence department is that the collection ability is far greater than the analysis and processing ability, and described this dilemma with a large amount of data piled in the warehouse. It can be seen that the challenge of intelligence agencies in the era of intelligence 3.0 has changed from occupying information as comprehensively as possible to using information effectively. The focus of intelligence work is how to effectively implement information filtering under the condition of information explosion, and then the Internet information that has not been processed by human brain is interpreted by intelligence workers to obtain information.

In 1997, the Department of science and technology of the CIA established the "the advanced analytical tools office" to implement information filtering through information technology, which is still in use today.

Figure 3 organization chart of CIA in 2017 (partial)

3. Establish Internet information processing tools to process information

3.0 information overload intelligence 3.0 environment, intelligence agencies must establish a batch of artificial intelligence tools to deal with internet information. The information stage discussed in this paper is universal and suitable for all kinds of information services, including scientific and technological information services.

The information source of scientific and technological information service also takes the Internet as the main carrier. With the rapid development of global big data and the geometric expansion of network information, the information overload of scientific and technological information is serious. Scientific and technological information workers can not select valuable information from a large number of information by manpower alone, and need to master advanced analysis tools to assist in research and judgment.

Scientific and technological information service institutions need to establish intelligent analysis tools to provide tool support for scientific and technological workers from four aspects.

3.1 information concentration

Scientific and technological information service institutions should establish an intelligent information base to integrate all information sources, so that scientific and technological information workers can retrieve all the information they should know through a single information base, that is, data association network.

Scientific and technological information workers can improve the efficiency of information production from the following aspects by retrieving information through a single database with comprehensive information:

① The information scattered in different places is retrieved and centralized;

② Focus on processing information according to different needs of information analysis and refining the value of information duplication; ③ avoid the loss of important information caused by incomplete database information.

3.2 information dynamic automatic classification

Scientific and technological information service institutions shall establish information classification tools, which shall meet the following requirements:

① Information classification should meet the needs of scientific and technological information interpretation, and on the basis of expert simulation, it is fast and convenient to search;

② Information classification should be convenient for scientific and technological intelligence workers to compare similar information, such as: it is easy to find new rules and discoveries from continuous events, and even information classification should be able to automatically determine specific information or new types of information.

③ Complete information measurement.

3.3 information intelligent filtering

Artificial screening information has contingency and uncertainty. Tools can not only help science and information workers to extract relevant information from information swamp, but also can simulate expert intelligence to make information analysis method develop steadily.

As mentioned above, information explosion and information flooding are the main problems faced by science and technology intelligence workers in the era of information 3.0. Compared with information concentration and information classification, information filtering is one of the most important problems to be solved by science and technology intelligence service agencies in establishing information tool system.

For example, suppose that there are 20 million pieces of information for a certain problem, including 600 pieces of relevant information. Among these 600 pieces of information, analysts can only read 100 pieces of the full text of information due to time and workload constraints.

The selection of 600 pieces of information from 20 million pieces of information is beyond the reach of human resources and needs the support of information technology tools. At present, 100 pieces of valuable information are selected from 600 pieces of relevant information, which still rely on manual analysis and judgment by analysts.

The working time and accuracy of 100 pieces of valuable information selected from 600 pieces of information are restricted by the analysis ability of analysts.

And the best intelligence experts can not guarantee to select all valuable information completely and accurately, especially in the case of not reading through the full text of the material, it is difficult for human to identify the relevance in the information, especially the secondary relevance. It needs the support of intelligence analysis tools to correctly judge whether all information is valuable.

In terms of information filtering function, information analysis tools can assist scientific and technological information workers in studying and judging information from the following aspects:

① Intelligent filtering information

② Extract articles from events or keyword families that analysts are interested in (instant generation of Thesaurus)

③ Through intelligent logic judgment, target intention understanding, establishment of intelligence model system and other means, intelligence filtering tools are developed to make information technology replace artificial research to judge whether information is valuable. The accuracy of information filtering should reach or even exceed the level of artificial research.

④ Intelligent mining information content contains association relations.

3.4 forming information production process

Lay the foundation for the popularization of information, solidify the expert wisdom in the information production line, so that ordinary intelligence workers can also produce high-quality information reports, and solve the problem of information aristocracy. Through the realization of information production process, lay the foundation for information popularization.

4 concluding remarks

Starting from the information production factors in each information period, this paper makes a distinction and comparison between the information work in the information carrier, the key point of information judgment and the task of information work in the Information 1.0 era, the information 2.0 era and the information 3.0 era. Through the comparative analysis with other information periods, it highlights that the new challenge of information work in the information 3.0 era is to study and judge the massive information on the Internet, and accordingly proposes that intelligence agencies should establish intelligent analysis tools to assist analysts in information analysis.
