Research On The Order Measure Model And Evolution Laws Of Collaborative Knowledge Structure

As an effective tool which can reveal knowledge flowing and internal relations of knowledge, the knowledge structure has always been widely concerned. With the development of Web2.0, People's growing social demands promote mutual integration of group wisdom, and a number of group knowledge structure which grow rapidly have been formed through self-organization, such as Wikipedia category knowledge structure, Folksonomy in social tagging system,etc., which will be defined as collaborative knowledge structure in this paper.The most existing researches have built the knowledge structure of a discipline or a field, make analysis of the development process and research emphasis using statistical analysis, knowledge mapping, but very few scholars are concerned about the formation mechanism and development mode of collaborative knowledge structure, or the further exploration of the measure of the overall knowledge structure, or the evolution degree of knowledge structure. Existing methods also exist in the time lag and can not reflect the real-time knowledge structure.Therefore, this paper regards Wikipedia as an example. Firstly, according to cognitive coordination theories, this paper gives us an analysis of collaborative cognition mechanisms and cognitive processes. Secondly, structural entropy model and measure indicators of Wikipedia information quality have been introduced, and the order measure model of collaborative knowledge structure in Wikipedia has been designed. Through experiments, the evolution laws of the whole collaborative knowledge structure and the intersection between them have been summarized. Finally, the influencing factors of structural stability have been further studied.This research has not only enriched collaborative cognition theory, but also found the evolution law of collaborative knowledge structure from the perspective of order, the model mentioned above provides a good foundation of quantitative measurement in collaborative knowledge structure. In addition, the study on influencing factors provides a theoretical basis on controlling of the orderly development of collaborative knowledge structure in Wikipedia.
