Using ontologies and the web to learn lexical semantics
Aarti Gupta, Tim Oates · 2007
A variety of text processing tasks require or bene-fit from semantic resources such as ontologies and lexicons. Creating these resources manually is te-dious, time consuming, and prone to error. We present a new algorithm for using the web to de-termine the correct concept in an existing ontology to lexicalize previously unknown words, such as might be discovered while processing texts. A de-tailed empirical comparison of our algorithm with two existing algorithms (Cilibrasi & Vitanyi 2004, Maedche et al. 2002) is described, leading to in-sights into the sources of the algorithms ’ strengths and weaknesses. 1
