Attribute Value Acquisition through Clustering of Adjectives

In the paper we analyse Polish descriptive adjectives which occur in domain related texts. The experiments were done on data obtained from hospital discharge records. Prenominal adjectives selected from these texts were filtered out of presumably relative adjectives and clustered on the basis of a set of context related features and interword relations derived from Wordnet. We tested if this procedure can be used to automatically identify concept features, i.e. whether adjectives representing different values of one feature will form one cluster. The obtained results proved to be useful as a preprocessing step in a specialized subdomain ontology creation procedure.
