Peer reviewedSrinivasan, Uma; Ngu, Anne H. H.; Gedeon, Tom – Journal of the American Society for Information Science, 2000
Introduces a conceptual integration approach to heterogeneous databases or information systems that exploits the similarity in metalevel information and performs metadata mining on database objects to discover a set of concepts that serve as a domain abstraction and provide a conceptual layer above existing legacy systems. Presents results of…

Peer reviewedChen, Hsinchun; Houston, Andrea L.; Sewell, Robin R.; Schatz, Bruce R. – Journal of the American Society for Information Science, 1998
This study found that a Kohonen self-organizing map (SOM) algorithm for browsing can categorize a large and eclectic Internet-information space into manageable sub-spaces that users can navigate to find relevant home pages. An automatically generated concept-space algorithm for searching was shown to enhance keyword-based Internet searching.…
