A semantic integration system for heterogeneous bioinformatics data

A data integrating system, designed to provide unified access to multiple, heterogeneous biological and medical data sources, is proposed in this paper. Compared with other analogous systems, a linear regression model is used to improve the efficient of ontology alignment by results of string-based ontology alignment algorithms. We build domain ontology from object-oriented perspective to integrate bioinformatics information stored in relational databases, and describe the detailed process of heterogeneous data integration.
