摘要

With the rapid development of Web2.0 technology,more and more social annotation systems are emerging,such as Del.icio.us,Flickr,YouTube,and CiteULike.These systems help users to manage and share their digital resources,and have attracted a lot of users to annotate the resources with tags and bookmarks,which result in a large scale of tag data.Due to the exponential increase of social annotations,all the users are facing the same problem:How can we explore the desired resources efficiently in such a large tag dataset?Since the traditional methods such as tag cloud view and annotation match work well only in small annotation dataset,this paper studies the relationships of tag-tag,tag-resource and resource-resource through the co-occurrences and proposes a new efficient way for users to organize and explore the literature resources.Our research mainly focuses on two aspects:1)The hidden semantic relationships of popular tags and their relevant literature resources;2)the computing of literature resources similarity given a specific literature.A prototype system named PKUSpace is implemented and shows promising results.
