UKB: Graph Based Word Sense Disambiguation and Similarity

UKB is a collection of programs for performing graph-based Word Sense Disambiguation and lexical similarity/relatedness using a pre-existing knowledge base.

UKB has been developed by the IXA group in the University of the Basque Country. UKB applies the so-called Personalized PageRank on a Lexical Knowledge Base (LKB) to rank the vertices of the LKB and thus perform disambiguation. The details of the method are described in [1]. It has also been applied on WSD on specific domains [2]. The algorithm can also be used to calculate lexical similarity/relatedness of words/sentences. See [3] for an application of UKB based similarity.
