Research On The Behavior Space Construction,Trajectory Predicting And Guidance Of College Students' Network Information Exchange Behavior

College students are active in thinking and are open to embrace emerging information technologies.They are also an important part of the development of China's network society,a keystone to construct the political,economic and cultural aspects of China's network society.Internet provides various kinds of convenience for college students,but may also undermine the overall development of college students.When college students are exposed to the non-health information in the Internet,they are vulnerable to the influence of such negative information due to their inexperience and low emotional stability,thus resulting in anomie network information exchange behavior.College students are high-quality groups among netizens.They should play a leading role in the construction of network environment and contribute their strength to the construction of a clean cyberspace as rational network citizens.Therefore,it is of great theoretical and practical significance to study and judge the network information exchange behavior of college students.The network information exchange behavior of college students is a process of sharing,communicating and exchanging information resources according to their own information needs inside the cyberspace.It is a realistic problem for the government,society,information platform and universities to swiftly locate and respond unhealthy information exchange behavior of college students.Through literature review,the network information exchange behavior of college students could be explained as a complex aggregation of the college students,information need,information resources,information scenario and specific information exchange behaviour.Due to the nature of concealment,mutation and randomness of college students' network information exchange behavior,a new method integrating qualitative analysis and quantitative calculation is urgently needed to study and judge it,so as to improve the efficiency and effectiveness of College Students' network information exchange behavior prediction and guidance.With the in-depth thinking of the above problems,this paper attempts to provide a more objective analysis and prediction method of college students' network information exchange behavior based on the relevant theoretical and practical research of college students' networkinformation exchange behavior space construction and information exchange behavior trajectory prediction.The current research on the analysis,prediction and guidance of College Students' network information exchange behavior is relatively fragmented.Most of the researches focus on the individual students instead of a student group,and most of them focus on one specific network information exchange behavior in particular information scenarios.There is a lack of systematic research on the quantifying and judging of college students' group network information exchange behavior.In view of this,this paper synthesizes the advantages of information science,management science,computer science,statistics,ideological and political education and other disciplines to jointly to clarify the concepts and principles and to deeply analyze the mechanism of information exchange behavior space construction and trajectory prediction.The feasibility of the model is discussed by empirical research.At last,we use the relevant theories of network information exchange behavior space construction and trajectory drawing to fulfil the guidance of college students' group network information exchange behavior,therefore enrich the connotation of college students' group network information exchange behavior theory and practical application.The main contribution of this paper include the following aspects:Firstly,by combing the relevant literature at home and abroad,referring to the relevant theories and methods of information behavior,this paper discusses the connotation,extension and concept of college students' group network information exchange behavior,and concludes that the college students' group network information exchange behavior is mainly attributed to college students,college students' network information need,network information scenario and specific information exchange behavior.This paper also analyzes the characteristics of these four elements.Secondly,the concept,goal and principle of network information exchange behavior space construction of college students are put forward.Then the relationship between network information exchange behavior space construction and network information exchange behaviortrajectory drawing of college students is demonstrated.This paper expounds the attribute selection,data selection,network weighting and model construction mechanism of college students' network information exchange behavior space construction.By using the improved data envelopment analysis,centrality analysis,Page Rank algorithm,support vector machine algorithm,text clustering algorithm based on clustering validity indices,entropy weight method and other methods,the theoretical model of college students' network information exchange behavior space construction is established,the calculation methods of each measure in the index system and index system itself are summarized.Through empirical research the validity of each model is clarified.Then the college students' network information exchange behavior space is constructed and the pre-theoretical analysis for the subsequent college students' network information exchange behavior trajectory drawing and prediction is completed.Thirdly,this paper puts forward the concept,goal and principle of drawing the network information exchange behavior trajectory of college students,and puts forward four mechanisms of data selection,function fitting,similarity calculation and model construction for college students' network information exchange behavior trajectory drawing/prediction.On top of that,The function fitting method including curve fitting,background trend line,gray system and trajectory similarity calculation method are used to establish the prediction model of college students' network information exchange behavior trajectory.The effectiveness of function fitting method and trajectory similarity method is analyzed,which provides a new method for the prediction method of college students' network information exchange behavior.Finally,based on the research conclusion of college students' network information exchange behavior space construction and trajectory drawing/predicting,the author extract three defining elements of network information exchange behavior categorizing: group activity,behavior health and behavior stability.Based on these three elements,the author provide a theory support for the guidance of college students' network information behaviour.College students' network information exchange behavior space construction and trajectory drawing is an important theoretical tool for the prediction and guidance of college students' network information exchange behavior.Through mathematical model and computer programming,we can apply the theory of college students' network information exchange behavior space construction,trajectory drawing and prediction to practice,and provide new research methods for the related research of college students' group network information exchange behavior.
