Logsonomy - A search engine folksonomy

In social bookmarking systems users describe book-marks by keywords called tags. The structure be-hind these social systems, called folksonomies, can be viewed as a tripartite hypergraph of user, tag and re-source nodes. This underlying network shows specific structural properties that explain its growth and the pos-sibility of serendipitous exploration. Search engines filter the vast information of the web. Queries describe a user’s information need. In response to the displayed results of the search engine, users click on the links of the result page as they expect the answer to be of relevance. The clickdata can be represented as a folksonomy in which queries are descriptions of clicked URLs. This poster analyzes the topological character-istics of the resulting tripartite hypergraph of queries, users and bookmarks of two query logs and compares it two a snapshot of the folksonomy del.icio.us
