ONTOLOGICAL WAREHOUSING ON SEMANTICALLY INDEXED DATA - Reusing Semantic Search Engine Ontologies to Develop Multidimensional Schemas

Abstract

In this article we present a first experimentation of a Business Intelligence solution to dynamically develop multidimensional OLAP schemas through a reuse of ontologies, stored in concept and relations dictionaries and used by semantic indexing engines. The particular aspect of the proposed solution consists in the integration of semantic indexing techniques of non-structured documents, based on ontologies, with dynamic management techniques of unbalanced hierarchies in a Data Warehouse. As a case study, we embedded our solution into a real system, built for the analysis and management of experts’ curricula in an e-government environment. We show how it is possible to automatically build OLAP dimensions, inheriting the hierarchic structure of ontologies, with the goal of using the semantically indexed data to carry out multidimensional OLAP analyses. The first experimental results are encouraging.
