SemKey: A Semantic Collaborative Tagging System
Andrea Marchetti, Maurizio Tesconi, Francesco Ronzano, Marco Rosella, Salvatore Minutoli · 2007
By analysing the current structure and the usage patterns of collaborative tagging systems, we can find out many important aspects which still need to be improved. Problems related to synonymy, polysemy, dierent lexical forms, mispelling errors or alternate spellings, dierent levels of precision and dierent kinds of tag-to-resource association cause inconsistencies and reduce the eciency of content search and the eectiveness of the tag space structuring and organization. They are mainly caused by the lack of semantic information inclusion in the tagging process. We propose a new way to describe resources: the semantic tagging. It allows user to state semantic assertions: each of them expresses a defined characteristic of a resource associating it with a concept. We present SemKey, a semantic collaborative tagging system, describing its global architecture and functioning along with the most relevant organizational issues faced. We explore the adequacy of the support oered by the entries of Wikipedia and WordNet in order to access to and reference concepts.
