Naphtali David Rishe, Rukshan Athauda, Jun Yuan, Shu‐Ching Chen · 2000
Obtaining useful, complete, accurate information from on-line web data sources has become a challenging issue with multiple heterogeneous data sources on-line. With the increase of structured data sources moving on-line, collective integrated access to such information sources requires resolving semantic heterogeneity using innovative techniques for integration and query processing. In this paper, we provide a theoretically sound, complete and unambiguous approach to resolving semantic heterogeneity using semantic knowledge. Advantages of using such knowledge in integration and query processing, such as acquiring additional information, complete answers to queries and techniques for intelligent query optimization are outlined. 1. Introduction With the advent of the Internet, multiple heterogeneous structured data sources available online has increased, and thus created a need for access to these heterogeneous data sources in a collective manner. The World-Wide Web (WWW), usually, ca...
