Monolingual and bilingual dictionary approaches to the enrichment of the Spanish WordNet with adjectives

We report on two different approaches to the incorporation of adjectives in Spanish WordNet based on automatic extraction techniques using EuroWordNet and machine-readable dictionaries. We show that a monolingual dictionary approach enables to exploit relations between different parts of speech and enrich the internal structure of the Spanish WordNet, while the methods based on bilingual dictionaries allow to connect the new items with the rest of the wordnets through the EuroWordNet InterLingual Index.
