Augmenting domain-specific thesau with knowledge from wikipedia is a 2008 conference paper written in English by Medelyan O., Milne D. and published in New Zealand Computer Science Research Student Conference, NZCSRSC 2008 - Proceedings.
We propose a new method for extending a domain-specific thesaurus with valuable information from Wikipedia. The main obstacle is to disambiguate thesaurus concepts to correct Wikipedia articles. Given the concept name, we first identify candidate mappings by analyzing article titles, their redirects and disambiguation pages. Then, for each candidate, we compute a link-based similarity score to all mappings of context terms related to this concept. The article with the highest score is then used to augment the thesaurus concept. It is the source for the extended gloss, explaining the concept's meaning, synonymous expressions that can be used as additional non-descriptors in the thesaurus, translations of the concept into other languages, and new domain-relevant concepts.
