Abstract
Conference Title: 2015 IEEE 9th International Conference on Research Challenges in Information Science (RCIS) Conference Start Date: 2015, May 13 Conference End Date: 2015, May 15 Conference Location: Athens, Greece On-Line Analytical Processing (OLAP) has generated methodologies for the analysis of structured data. However, they are not appropriate to handle document content analysis. Because of the fast growing of this type of data, there is a need for new approaches abling to manage textual content of data. Generally, these data exist in XML format. In this context, we propose an approach of construction of our Diamond multidimensional model, which includes semantic dimension to better consider the semantics of textual data In addition, we propose new aggregation operators for textual data in OLAP environment.
