An Approach for the Extraction of Information from Heterogeneous Sources of Textual Data
Sonia Bergamaschi, Claudio Sartori · 1997
Extracting informations from multiple sources of textual data and integrating them in order to provide information is a challenging research topic in the database area. This paper presents a Description Logics approach to provide solutions both for data integration and data querying. The approach includes: a common description of sources, compliant with a subset of ODMG93; Description Logics techniques to optimize information extraction and to implement mediators (i.e. components which integrate and refine the data coming from the different sources).
