The definition of resources: refers to all objective forms of existence in nature and human society that can be used to create material wealth and spiritual wealth.
Definition of information resources
Broadly speaking: Information resources can be various information and corresponding talents and technologies used to create material and spiritual wealth. It is a general term for resources related to information activities.
Narrow sense: Information resources refer to all kinds of information that can be used by humans to create wealth.
The relationship between information and information resources
The relationship between information and generalized information resources: Cross-cutting relationships.
The relationship between information and narrow information resources: inclusion relationship. That is to say, not all information can become information resources. Only information that can be utilized by humans and used to create wealth and spiritual wealth can become information resources.

Distribution and change rules of information resources
Distribution law of information according to producers (Lotka's law)
Definition: There is a certain regularity between the frequency of authors writing a certain number of papers and the number of papers they write. x is the number of papers; c is a characteristic constant of a certain subject area; y(x) is the proportion of authors who wrote x papers to the total number of authors; a is a parameter, which is a constant for a specific subject area.
Formation mechanism: In the production of documentary information, there are always some producers who have a large amount of information production, and the information they produce is often cited by others. The concentration of producers is relatively high.
application
① Since Lotka’s law gives the relationship between information producers and production quantity, we can thus grasp the distribution level of information producers for the development and utilization of information resources.
② Lotka’s law reveals the ability laws of information producers, from which we can judge the laws of scientific labor results, optimize scientific labor organization, and improve scientific labor efficiency.
Word frequency distribution rules in information representation (Zipf’s law)
Definition: If you count the word frequency of each word in a long article (more than 5,000 words), sort it in descending order with high-frequency words first and low-frequency words last, and use natural numbers to number these words. That is, the most frequent word is graded 1, the next highest grade is 2...the word with the smallest frequency is graded D. If f is used to represent the frequency of a word appearing in an article, and r represents the rank number of the word, then f·r=c, and c is a constant that fluctuates up and down around a central value.
Formation mechanism: When people use words to express information, they seem to receive two opposite effects. On the one hand, they hope to be understood by the other party, and on the other hand, they hope to be as brief as possible. The distribution of natural language vocabulary is hyperbolic. No matter what kind of literature information source, the subject words or keywords are Zipf distributed.
Application: Zip's law reflects a universal law of human society. field of information science. Compilation of word lists, automatic indexing, document organization, and weighted indexing.
Distribution rules of professional papers in journals (Bradford’s law)
Definition: Within a certain time range, if scientific and technological journals are sorted in descending order according to the number of documents they publish in a certain subject field, and then divided into a core area and several other areas, each area publishes an equal amount of literature in this field. , then the number of journals in each district is 1:n:n square..., n is the Bradford constant and is greater than 1.
Formation mechanism: The development of science and technology and the publication of academic papers have created core journals and non-core journals, as well as core literature information resources and non-core literature information resources. As long as we sort the literature information resources required by users in descending order within a certain time range and divide them into several areas, we will find that when the total amount of literature demand in each area is equal, the information in the information sources in each area will The ratio of the total amount basically shows the trend of 1:n:n square... (n is a constant).
application
①Determine core journals
②Guide dynamic collections
③Comparison of subject maturity
④Judge the quality of search tools
information growth law
Exponential curve growth law: Price exponential growth curve, the curve equation is f(t)=ae (bt square) (b>0), F is the accumulation of literature at time t, t is time, a is the literature at the initial moment Accumulation amount, b is the continuous growth rate of the literature, and its value is approximately equal to the annual growth rate of the literature; e is the base of the natural logarithm.
Logic curve growth law: K is the maximum value of literature growth at a certain moment.
Formation mechanism: With the development of science and technology, the research field has expanded rapidly, there are more and more branches of disciplines, the scientific research team has continued to grow, scientific research funding has greatly increased, and scientific research activities continue to make discoveries, inventions, creations, and advances. . The emergence of a large number of scientific research results will inevitably lead to the continuous growth of scientific and technological documents recording scientific and technological achievements and knowledge.
application
①Technology management and forecasting
②Management of collection resources
Information aging rules
The so-called "half-life" of a document refers to how long it takes for the newer half of all the documents currently used in a certain discipline (major) to be published. This is roughly equivalent to the time it takes for half of the discipline's documents to expire.
Negative exponential aging law: C is the citation frequency of documents published in t years; k is a constant, which varies with different disciplines; e is the base of the natural logarithm; a is the aging rate.
Formation mechanism: Due to the rapid development of modern science and technology, as time goes by, the original immature theories are replaced by more mature theories, imperfect methods are supplemented by more complete methods, and less advanced technologies are replaced by more advanced ones. As technology is updated, erroneous and one-sided data are corrected by more objective facts, so the old literature information gradually becomes invalid.
application
① Guide the deletion of collections of documents
②Determine the scope of data collection during scientific research
③Explain the laws of scientific development
3. Information users

②Temporary users: Non-registered supernumerary users refer to users who have not established a formal relationship with the information organization and have not registered with the information organization but temporarily use the information organization.
③Potential users: refers to users who should or are likely to contact information agencies and have not yet used information agencies.
The three have a certain degree of relativity and can be transformed into each other.
User information needs
The concept and hierarchy of user information needs
Concept: Users' information needs are users' needs and requirements for information. User needs are the needs and specific requirements of information users for information content, quantity, quality and form.
The user's information needs can only be the user's request for the information itself, but cannot include the user's demand for information services. The user's demand for information services is an aspect of the user's information acquisition behavior.
level
① Deep information needs: that is, the actual information needs of users, which refers to the form of composition and nature of work of users; it is all the information required by users to achieve a certain purpose, including conscious needs and unconscious needs.
objective information needs
②Mid-level information needs: that is, information needs recognized by users, excluding information needs that have not been recognized and discovered by users.
③Surface information needs: that is, the information needs expressed by users, which refers to the information needs expressed by users orally or in writing.
Factors affecting users’ information needs (3)
①Environmental factors (6): refers to the living environment where users live, including social environmental factors and natural environmental factors.
The commonality of user information needs is the most important
①Social and political factors
②Science and technology development level

③Age and gender
④Hobbies and expertise
⑤Information awareness and information ability
The rules and characteristics of individual users’ information needs
General rules (4)
① Progressivity: People have different levels of needs and different needs for information. The higher the level of needs, the greater the demand for information and the higher the requirements for information quality.
②Multiplicity: At the same time, a user's needs for information coexist for different purposes, different content properties, and different levels of needs.
③ Phase: Users’ information needs are divided into primary and secondary at the same time. The main information content required by users always shows phased changes as time goes by.
④Matthew Effect and Robin Hood Effect: Users with large information needs will have higher and higher information needs as time goes by; users with small information needs will have lower information needs as time goes by. The demand is getting lower and lower than the average level, while the information needs of most users are always relatively balanced. The two effects reflect the distribution and development changes of user information demand.
Characteristics of information needs of different types of individual users (content, form, characteristics)
