Sintagma Nominal em Estrutura Hierárquica Temática na Recuperação de Informação

Marco GonzalezVera Lúcia Strube de Lima

Noun phrase (NP) is essentially the part of a sentence with subject or object behavior. NP had been viewed as a referring expression and in this paper its components are analyzed. The semantic function of each one is considered for constructing a thematic hierarchical structure for NP representation. This is a NP format that can be tractable by information retrieval (IR) systems as index and query term. With this approach and with thesaurus utilization, benefits are obtained in IR: (a) query in natural language, (b) use of the same process to identify themes on indexing and query, and (c) improvement on the similarity evaluation in the documents search.
