Abstract

This essay proposes a model called information genetics (IG) to elaborate on the origin of information generating. The model builds on a broad information generating force that is both cause and effect. Part I of this essay postulates this information generating force as the result of the interaction and intermediation among four subforces: Query, command, statement, and term-term bond. These subforces are described by a process called twisting-bonding/clipping-jointing. The effect of this process is elaborated by: (1) Analyzing the Information Generating Model (IGM); (2) Transfiguring the Möbius Strip into the Möbius Twist Model; and (3) Demonstrating the process of the Clipping-Jointing Model. These three models are defined, exemplified, and described in detail. In Part II, a Fuzzy Commonality Model (FCM) is introduced to describe and explain the formation of a network curvature and to measure the dynamics of the twisting-bonding/clipping-jointing process within any special subject information field. In Part III, a software program is developed through the FCM for citation data mining, infomapping, and information repackaging--the three key elements in total quality knowledge management (TQKM). The conceptual and data models are supported by practical examples and statistical data. Several information flows are displayed in parallel to show their twisting-bonding/clipping-jointing interaction and intermediation relationships. This paper discusses the significance and advantages of the information genetics models and their approachability and applicability for TQKM in infomapping and Web information representation. The meaning of the information genetics models is also examined from a global perspective.

Abstract

Information landscaping--an integration of information mapping, charting, querying and reporting techniques--has been developed to enable the construction of a total quality knowledge management system focusing on a particular subject information field. The techniques apply five major parameters of the Fuzzy commonality model (FCM) including unionization, quantity, continuity or stability, changeability, and critical probability, to construct a series of information maps (infomaps) and a set of chronological-statistical charts (infocharts). The infomaps and infocharts are used as the blueprints and navigation agents for building and developing a web-based subject experts depository and query-report system. Focusing on the subject experts/expertise, this system enables a researcher to expedite a query search through infomaps (qualitative reference) and infocharts (quantitative reference). The entropy measurement and the entropy constant (the square root of the average entropy measure) are calculated to compare with the critical probability of the FCM. This leads to the finding of a set of regression straight lines and the establishment of an information oscillogram. The tropics (upper limit, middle range, lower limit), and the potential/solstitial population and its growth rate within a subject information domain during a particular time period can be determined. They can effectively and efficiently guide librarians and information professionals towards the construction and the continuous development of an electronic collection. The cultivation of a virtual learning and referencing environment can also be created by utilizing this data.

Abstract

Capability and capacity in handling the topology of a special subject information field has made infomapping techniques and systems instrumental in information searching, monitoring and navigation. Applying the technique to communication networks can reveal the intellectual relationships among junior and senior researchers in the field, and can also show the continuing popularity of a particular researcher's citation record over time. Reports the use of Java in making a cartoon series of chronological maps based on citation analysis on a special subject field (nutrition and dietetics). The map making methods, Java programming, and statistical analysis of the map data are presented, and the advantage and significance of constructing Java maps in enhancing information retrieval discussed. Further technical developments in applying VRML to link together a 3-D spatial indexing system and a 2-D HTML Web site are suggested
