Enriching Concept Search across Semantic Web Ontologies

Chetana Gavankar, Vishwajeet Kumar, Yuan-Fang Li, Ganesh Ramakrishnan
2013 International Semantic Web Conference  
Towards this objective, we propose a novel approach of indexing concepts using ontology axioms in an inverted file structure and ranking them using a dynamic ranking algorithm.  ...  A preliminary evaluation indicates that our proposed method is effective, outperforming the search function of BioPortal, a large and widely-used ontology repository.  ...  In future we plan to learn these weights using machine learning algorithms. The weight of concept c in the ontology corpus, denoted W c , is calculated as follows: W c = λ.  ...
