Mining for semantic information in search engine query logs bears great potential for both the optimization of search engines and bootstrapping Semantic Web applications. The interaction of a user with a search engine (more specifically clicklog information) has recently been viewed as implicit ta ...

Recent research has demonstrated how the widespread adoption of collaborative tagging systems yields emergent semantics. In recent years, much has been learned about how to harvest the data produced by taggers for engineering light-weight ontologies. For example, existing measures of tag similarity ...

Social bookmarking systems are becoming increasingly important data sources for bootstrapping and maintaining Semantic Web applications. Their emergent information structures have become known as folksonomies. A key question for harvesting semantics from these systems is how to extend and adapt trad ...
