The paper “The People's Web meets Linguistic Knowledge: Automatic Sense Alignment of Wikipedia and WordNet” by Elisabeth Niemann and Iryna Gurevych has been accepted at the International Conference on Computational Semantics (IWCS) 2011.

Abstract:

We propose a method to automatically align WordNet synsets and Wikipedia articles to obtain a sense inventory of higher coverage and quality. For each WordNet synset, we first extract a set of Wikipedia articles as alignment candidates; in a second step, we determine which article (if any) is a valid alignment, i.e. is about the same sense or concept. In this paper, we go significantly beyond state-of-the-art word overlap approaches, and apply a threshold-based Personalized PageRank method for the disambiguation step. We show that WordNet synsets can be aligned to Wikipedia articles with a performance of up to 0.78 F1 -Measure based on a comprehensive, well-balanced reference dataset consisting of 1,815 manually annotated sense alignment candidates. The fully-aligned resource as well as the reference dataset is publicly available.
