Abstract
This work presents the results of the application of a technique for automatic extraction of semantic relations among words from a corpus. The technique used is the one proposed by Grefenstette in [1]. We brought contributions to the syntactic context notion in [1], aiming to improve the identification of semantically related words. Then, we carried on three different experiments using a Portuguese language corpus: the first one compares the original Grefenstette's technique with the technique modified with our contributions, the second experiment investigates which syntactic relation is more relevant when identifying semantic relations, and the last experiment investigates the influence of the parser errors on the quality of the extracted semantic relations. Results and their analyses are detailed in this article.
