Abstract： [Purpose/significance] The sticky context of mobile library information is an active factor that hinders the acceptance of information. Reducing the sticky degree of information acceptance context and enhancing the adaptation effect of "Scence-Behavior-Context" of information acceptance in mobile library is the key to enhance mobile library's scene service ability and realize the innovation of mobile library services.[Method/process] Through the formation of motivation research of mobile library information acceptance context stickiness, the use of context adaptation theory and block growth model theory, the model of mobile library information acceptance context of stickiness effects was constructed; mobile library information scene elements, accept context factors and adaptation factors on mobile library information acceptance context was simulated by the Matlab dynamic viscosity.[Result/conclusion] Experimental results show that the mobile library information to accept the context of stickiness has different characteristics in different stages. Too small stickiness will make the mobile library information acceptance context to produce severe shock effect on mobile service scene, while the large viscous will make the mobile library information acceptance scene relies on the information acceptance context.

Abstract： [Purpose/significance] In order to improve the satisfaction of user information acceptance experience, it is a practical problem that needs to be solved in the mobile library to find out the user's expectation of information requirement, information search habit and preference of information acceptance, and to match the content of the user's sceneIn order to improve the user's pleasure of accepted experience in different scenes in mobile library, it is necessary to effectively excavate the users' expectation of information requirements, information search habits and information acceptance preference in different scenes, for users in the scene to accept the information content. [Method/process] Using the theory of microaggregation, the multi-dimensional analysis of user context is carried out, and the content adaptation framework of the scene based information acceptance of mobile library is built through the scene recognition. From the perspective of "Scene-Content-Context" adaptation, the mechanism model of content adaptation of information acceptance in mobile library is constructed. [Result/conclusion] Taking YunZhou knowledge service space as an example, this paper analyzes the degree of information acceptance content adaptation, and puts forward the content adaptation path of mobile library's scene information acceptance.

Abstract： [Purpose/significance] Scenario information acceptance context of mobile library affects users' information demands, and users' information demands come from the potential difference between their own comprehensive literacy and the ability to solve target problems. In the era of micro media, self media and all media, it is the key of mobile library information service to study demands and characteristics of the scenario information in mobile libraries and to excavate the rule of users' information demands. [Method/process] Firstly, we regarded mobile library as an integrated system, studied the connotations, elements and characteristics of users' scenario information demands from the perspective of system theory. Then, based on the social cognition theory, user satisfaction theory and self-regulation theory, we summarized scenario information demand rules of mobile library, and did empirical research on user scenario information demand rules though the method of log mining method. [Result/conclusion] The results show that different single users' information demands have different advantages, such as chain, branch, tree and mesh. However, for user groups, their information demands are in strict accordance with the trend of "Chain-Branch-Tree -Network".

Abstract： [Purpose/significance] The most important feature of digital reading in mobile era is its interaction. However, the existing theoretical research is less about the interaction mechanism and interaction effect of mobile social reading. It is necessary to reveal the interaction mechanism and interaction effect of digital reading in the mobile social era.[Method/process] Through combing the different dimensions of the existing mobile social interaction reading, we clarify the interaction method and interaction relation between mobile social reading from the three levels of interaction chain, interaction domain and interaction field,then we construct the interaction mechanism of mobile social networking reading and from the double perspectives of interaction process and interactive results, we analyze the interaction effect of it. Finally, we make an empirical research of mobile social reading by an example of "YunZhou" knowledge service space.[Result/conclusion] Through the study of reading interaction mechanism and effect of mobile social networking, we clarify the mobile social network interaction context,which is conducive to promote the interaction from homogeneity to heterogeneity in transformation and integration and realize the precision and personality of mobile social networking reading services.
