| Along with the development of technologies such as the Internet of Things,cloud computing and mobile Internet,web-based reading and learning has become one of the main ways to acquire knowledge in the Internet era.Knowledge sharing,creation,and management based on virtual communities and knowledge sharing communities are important research areas in computer and library intelligence disciplines.In response to the lack of active user sharing,the short life cycle of knowledge communities,and the insufficient quantity and quality of knowledge community content that still exist in knowledge community online operations and knowledge sharing community research.and relatively little research has been conducted on the construction of knowledge sharing communities based on specific objects of university faculty and students.Guided by knowledge sharing theory from three perspectives of sociology,psychology and technology acceptance,this paper analyzes and designs the core elements of dynamic knowledge sharing communities in colleges and universities,constructs a model of dynamic knowledge sharing communities in colleges and universities,and designs a prototype system of dynamic knowledge sharing community platform.In order to build a knowledge exchange,sharing and creation platform centered on the users of university teachers and students.The main work of this paper includes the following aspects:(1)Design of core elements for dynamic knowledge sharing communities in higher education.Firstly,a model of two types of community user subjects,students and staff,was specifically designed in terms of basic reader information and book lending behavior data;secondly,a model of factors influencing dynamic knowledge sharing communities in universities was explored and designed in three dimensions and14 aspects of knowledge sharing subjects,environment and content;Finally,according to the data mining of book themes of book lending data every six months,the KMeans++ algorithm is used to cluster the book title data etc.that have been divided into words,and the category with the largest number of cluster samples is selected through analysis so as to determine the current theme,and the shared community theme is set dynamically in a six-month cycle.(2)Model construction of dynamic knowledge sharing communities in higher education.It integrates the user subject elements,influencing factors and knowledge sharing theme community elements of dynamic knowledge sharing communities in universities,gives the principles of community construction,formulates the community management strategy,sets the community dynamic incentive mechanism,and builds a community based on knowledge sharing theory and knowledge sharing community support technology.A model of dynamic knowledge sharing community in universities with interconnection among three core elements of knowledge sharing community.(3)Prototype system design for dynamic knowledge sharing communities in higher education.The prototype system of college knowledge sharing community platform is designed based on the core elements of college knowledge sharing community and the constructed model,and the functions of thematic community recommendation,you-ask-me-answer and community creation of the knowledge sharing community are designed. |
