| Abstract | We describe an experiment wherein a word space model is used to automatically extract lexico-semantic relations from specialized corpora. Results show that an unstructured model, which exploits basic word cooccurrence information, can effectively identify paradigmatically related terms (near synonyms, antonyms, hyponyms) given a target term. We discuss the parameter selection and evaluation methodologies, which rely on data extracted from a specialized dictionary. We analyze the impact of parameters such as the shape and size of the context window, the weighting scheme and the use of dimensionality reduction. We also compare the relations identified in two specialized corpora, one dealing with the environment and the other pertaining to natural language processing. Mots-cles : Semantique distributionnelle, semantique computationnelle, relations lexico-semantiques, corpus spe- cialise, terminologie. |
