Abstract: Today folksonomies are of increasing importance, many different platforms emerged and millions of people use them. We consider the case of a user who enters such a social platform and wants to get an overview of a particular domain. The folksonomy provides abundant information for that task in the form of documents, tags on them and users who contribute documents and tags. We propose a process that identifies a small number of thematically ”interesting objects” with respect to subject domains. Our novel algorithm CrossSense builds clusters composed of objects of different types upon a data tensor. It then selects pivot objects that are characteristic of one cluster and are associated with many objects of different types from the clusters. Then, CrossSense collects all the folksonomy content that is associated with a pivot object, i.e. the object’s world: We rank pivot objects and present the top ones to the user. We have experimented with Bibsonomy data against a baseline that select s the most popular users, documents and tags, accompanied by the objects most frequently co-occurring with them. Our experiments show that our pivot objects exhibit more homogeneity and constitute a smaller set of entities to be inspected by the user. (More)
