ExpOLAP: Towards exploratory OLAP

Traditionally, OLAP tools have been performed on static and structured data sources. Nowadays, there is plenty of data in different formats, such as the Resource Description Framework (RDF), a semi-structured and semantically-rich format external to the BI infrastructure. Although such data formats are enriched by semantics, performing data analysis is challenging. As a result, the Exploratory OLAP field has emerged for discovery, acquisition, integration and querying such data, aiming at performing a complete and effective analysis on both internal and external data. In this paper, we propose an innovative Exploratory OLAP approach that integrates on the fly semantic semi-structured and structured data sources.
