Abstract
The essential heterogeneity problem, also known as the semantic heterogeneity problem, becomes increasingly prominent as information sources expand rapidly in all kinds of subject domains, especially in the bio-informatics area which often deals with multi-terabyte datasets from various distributed sources. Traditionally, researchers use standards- or mediation-based methods to integrate heterogeneous information. This talk presents a novel approach to mitigate the essential heterogeneity for bio-informatics data sources. The approach is based on the proposition that, by monitoring, extracting, clustering, and visualizing bio-informatics metadata across disparately created data sources, patterns of practice can be identified and the definition of standards requirements can be facilitated, thereby promoting homogeneity of data sources. To instantiate the approach, a research architecture, microSEEDS, and its implementation and envisioned uses are discussed.
