Natural Language Processing Techniques

Spurred by the development of Universidade de Évora’s Integrated Information System (SIIUE) and on the authors' present research interests came the idea of a Natural Language Analysis System, which would provide a simple interface for getting access to existent information. This information is stored mainly in multiple object-relational databases. The system was built using a Logic Programming based approach as an application of the Logic Programming development tool ISCO. With it, the system can uniformly access heterogeneous external relational databases while doing syntactic and semantic sentence parsing. Although the main data sources accessed by the system described herein are the SIIUE databases, other existing databases can be integrated to be used by this system.
