In practice, however, they are always imperfect. This work analyzed whether the negative effect of ontology imperfection is higher than the positive effect of exploiting the ontology features for IR. To answer this question, a complete ontology-based information retrieval system was implemented and thoroughly evaluated.Fuzzy Mengeautomatic metadata generationOntologie <Wissensverarbeitung>fuzzy setprobability theoryInformation-Retrieval-SystemGenerierungUnvollkommenheitpossibility theoryMetadatenSemantic Webautomatische MetadatengenerierungWahrscheinlichkeitstheorieInformation RetrievalimperfectionontologyNagypál Gáborauth1283227BOOK9910346936903321Possibly imperfect ontologies for effective information retrieval3018995UNINA
