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 [3,4] for applications of UKB to similarity.
