Extracting lexical-semantic knowledge from the Portuguese Wiktionary

Authors

Abstract

Public domain collaborative resources like Wiktionary and Wikipedia have recently become attractive sources for information ex- traction. To use these resources in natural languague processing (NLP) tasks, efficient programmatic access to their contents is required. In this work, we have extracted semantic relations automatically from the Portuguese Wiktionary and compared our results with the relations in PAPEL, a public domain lexical network extracted from a proprietary dictionary. We have found about 44,000 relations that were not in PAPEL, which suggests that Wiktionary is a valuable alternative source for enriching existing lexical knowledge bases.
