Information management mind map
This is a mind map about information management mind map university. Information management is a science that studies the basic laws, universal principles and universal methods of information management activities in human society. The extensiveness and complexity of social information management phenomena require systematic and comprehensive research on it.

Way
Diachronic communication: CDs, documents, etc.
Eliminate time barriers
Simultaneous communication: telephone, fax, etc.
Eliminate spatial barriers
main body
The information transmitter S is also the producer of information
The information receiver R is also the user of information
communication process
Direct communication, face to face
Indirect communication: when someone participates, we also call this method an information chain
Single transfer, irreversible
It is stipulated that both parties in the communication have cognitive ability and have purpose
the act of exchanging information
Subjective information is objectified, objective information is subjectified
human behavior
purpose behavior
information behavior
non-informational behavior
Non-purpose behavior: behavior in a subconscious state
information exchange behavior
Output behavior: writing, speech
Receptive Acts: Reading, Artwork Acts

Meaning and characteristics
Information exchange is condensed and integrated, functional role elements are downplayed, and the entire communication activity is dominated by information flow.
The flow of information is accelerated, and the flow of information is increased.

information distribution
Distribution Law of Information Producers
Lotka's law
inverse square formula
X^nYx=C (Yx is the number of authors who published x papers
C=60.79%
The number of authors producing n papers is approximately 1/n^2 of the number of authors producing 1 paper.
Price's Law
m is the dividing line between core authors and non-core authors
Accumulate n(x) from i to m 1=N under the root sign
I=nmax is the number of papers produced by the most prolific authors in the discipline within a specified period.
Distribution of generators of network information
exponential growth rate
The distribution of producers is closely related to the degree of specialization of information content
Literature growth is an exponential function of time
F(t)=ab^bt (t is the doubling time of the literature volume, b is the sustained growth rate
Growth curve
F(t)=k/(1 ae^(-knt))
As time goes by, the growth rate becomes slower and slower, and K is the maximum value of literature growth.
Literature growth period
Birth and Development Period
period of rapid growth
stable period
Information aging
aging stage
The document is still useful but may be included in other new works
Still useful, but people are no longer interested
surpassed by later works
no longer useful
The larger the Price index, the smaller the half-life, and the faster the literature ages.
C=(t)=ke^(-at)(c(t) represents the number of citations of the document in year t, k is a constant, and a is the aging rate
Factors affecting aging
Literature growth
Subject differences
Differences in subject development stages
information environment and needs
Matthew effect
Core trends and focused orientations
Advantages: Highlight key points and improve efficiency
Disadvantages: Ignoring valuable information published in other information sources, limiting the dissemination of new ideas and knowledge

Internet information half-life
duration half life
synchronic half-life
How recently was the newer half of all the information cited or linked to a site in a certain time period published?
The life cycle of network information
growth stage, maturity stage, decline stage
The length of segment A-B will be much smaller than the length of segment C-D
Discrete distribution law
Bradford's Law
Laws of Dispersion and Concentration
Core area: related to: non-related area=1: a:a^2
The curved drooping part BD, we call it Grouse drop

Four dimensions of evaluation
Accuracy, completeness, consistency, timeliness
evaluate
