The Quest for Information Retrieval on the Semantic Web (2009)
David Vallet, Miriam Fernández, Pablo Castells
Abstract. Semantic search has been one of the motivations of the Semantic Web since it was envisioned. We propose a model for the exploitation of ontology-based KBs to improve search over large...

Using Historical Data to Enhance Rank Aggregation (2008)
Miriam Fernández, David Vallet, Pablo Castells
Rank aggregation is a pervading operation in IR technology. We hypothesize that the performance of score-based aggregation may be affected by artificial, usually meaningless deviations consistently...
Iván Cantador, Miriam Fernández, Pablo Castells, Escuela Politécnica
In this work, we present an extension of CORE [2], a tool for Collaborative Ontology Reuse and Evaluation. The system receives an informal description of a specific semantic domain and determines...
