Unsupervised Knowledge Extraction for Taxonomies of Concepts from Wikipedia
Unsupervised Knowledge Extraction for Taxonomies of Concepts from Wikipedia - scientific work related to Wikipedia quality published in 2009, written by Eduard Barbu and Massimo Poesio.
Overview
A novel method for unsupervised acquisition of knowledge for taxonomies of concepts from raw Wikipedia text is presented. Authors assume that the concepts classified under the same node in a taxonomy are described in a comparable way in Wikipedia. The concepts in 6 taxonomies extracted from WordNet are mapped onto Wikipedia pages and the lexico-syntactic patterns describing semantic structures expressing relevant knowledge for the concepts are automatically learnt.
