For tasks like synonym detection and discovery of concept hierarchies, many researchers introduced measures of tag similarity. Eventhough most of these measures appear very natural, their design often seems to be rather ad hoc, and the underlying assumptionson the notion of similarity are not made explicit. A more systematic characterization and validation of tag similarity interms of formal representations of knowledge is still lacking. Here we address this issue and analyze several measures oftag similarity: Each measure is computed on data from the social bookmarking system del.icio.us and a semantic grounding isprovided by mapping pairs of similar tags in the folksonomy to pairs of synsets in Wordnet, where we use validated measuresof semantic distance to characterize the semantic relation between the mapped tags. This exposes important features of theinvestigated similarity measures and indicates which ones are better suited in the context of a given semantic application.Thu Apr 03 11:17:43 CEST 2008Lexical Chains as representation of context for the detection and correction malapropisms1997hirst lexical relatedness semantic similarity Wed Oct 31 22:01:56 CET 2007Distributional measures as proxies for semantic relatednessSubmitted for publicationdistributional measure measures relatedness semantic similarity text Wed Oct 31 21:25:02 CET 2007OxfordStudies in Linguistic Analysis (special volume of the Philological Society)1-32A synopsis of linguistic theory 1930-55.1952-591957distributional measure measures relatedness similarity theory Reprinted in: Palmer, F.
