Dear list members,

we are pleased to announce the public release of version 0.1.0 of UKB, a collection of programs for performing graph-based Word Sense Disambiguation and lexical similarity/relatedness using a pre-existing lknowledge base.

UKB has been developed by the IXA group <http://ixa.si.ehu.es> 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]. The algorithm can also be used to calculate lexical similarity/relatedness of words/sentences. See [2] for an application of UKB on word similarity.

The software can be downloaded from:
