We describe the extension and objective eval- uation of a network1 of semantically related noun senses (or concepts) that has been au- tomatically acquired by analyzing lexical co- occurrencein Wikipedia. The acquisition pro- cess makes no use of the metadata or links that have been manually built into the ency- clopedia, and nouns in the network are auto- matically disambiguated to their correspond- ing noun senses without supervision. For this task, we use the noun sense inventory of WordNet 3.0. Thus, this work can be con- ceived of as augmenting the WordNet noun ontologywithunweighted,undirectedrelated- to edges between synsets. Our network con- tains 208,832 such edges. We evaluate our network’s performance on a word sense disambiguation (WSD) task and show: a) the network is compet...
