About

OnAIR (Ontology Aided Information Retrieval) is a system developed for searching within digital video databases. The systems indexes these databases, using a domain ontology. The user then, enters a query in Natural Language and the system uses the domain ontology to improve the quality of the retrieved data. The first version of the system (v1.0) was developped by Christian Paz-Trillo and Paula Braga under the supervision of Renata Wassermann at the Computer Science Department of the Mathematics and Statistics Institute - IME at the University of São Paulo - USP. We are currently working at the user interface improvement (including the development of a new Web 2.0 interface) and the domain ontology building process (including research on Ontology Alignment, Ontology Learning, Ontology Merging and Conflict Management).
