Exploring ontology-enhanced bibliography databases using faceted search

Abstract

In this paper, we exploited the application of the Ontology Based Data Access (OBDA) approach, equipped with faceted search utilities, to explore bibliography databases. A bibliography database is enhanced by means of an ontology leading to a bibliography information space. We show that faceted search paradigm to explore such information space is particularly attractive. We describe an implementation of this approach in DAFO system. We focus on formulating faceted queries over the ontology, mapping the ontology to a relational database, and on transforming the query to executable forms. The final version of a faceted query is a SQL query that is executed in a relational database system. The computational results show that the usage of faceted search-oriented way of modeling and retrieving information is very promising.
