Research On The Contextual Influence Factors Of Mobile Knowledge As Service

With the rapid development of mobile communication technology,the innovative knowledge services of multi-level,multi-form,multi-node and multi-agent emerge as the times require.Under the mobile background,the user's demand for knowledge service changes with the dynamic change of the surrounding situation.The changing situation factors will affect the user's different demand for knowledge service.Therefore,meets the real-time and situational sensitivity of users' knowledge service demand,and improves the quality of user access to mobile knowledge service.It will be an important research topic in this paper.Mobile knowledge Service(MKS)refers to the sum of interactive knowledge service processes that users can obtain personalized,accurate and situational knowledge services at anytime and anywhere with the help of mobile devices and mobile networks.The related researches at home and abroad mainly introduce the acceptance models of mobile Internet services,and the key factors that influence users to use mobile services.There are few literatures devoted to the empirical study of mobile knowledge services and situational factors.Based on this,this paper firstly reviews related literatures on knowledge service,mobile knowledge service,situational factors and theoretical basis.Secondly,on the basis of literature research and expert interview,this paper constructs a theoretical model of situational influence factors of mobile knowledge service,and then selects the knowledge service of university mobile library as the research object,and through the questionnaire survey method and the structural equation modeling method,this paper empirically discusses the influence of the situation factors on the quality of mobile knowledge service.The degree of interaction between situational factors,between situations and mobile knowledge services is also discussed.Finally,a modified model of situational factors for mobile knowledge services is obtained in this paper.The conclusions are as follows: the mobile knowledge service is directly or indirectly influenced by equipment situation,network situation,service situation,resource situation and user cognition situation;the direct impact of service context on mobile knowledge service is greater than that of resource context and user cognition context;user activity context has no significant impact on the quality of mobile knowledge service.This paper expands the theoretical research of the situation in the field of mobile knowledge service,constructs the situational influence factor model of mobile knowledge service,and integrates the "situation" factor into the mobile knowledge service field,and improves the efficiency and quality of user acquiring knowledge service Under the mobile background.It improves users' satisfaction with mobile knowledge services and improves user experience.
