| Research Abstract |
This research focused on fundamental techniques for information linkage to enable users to quickly identify and learn necessary information in a chaotic and fragmented mass of information. The proposed techniques include search indexes for efficient similarity search, an approximate calculation of tree similarity for large scale semi-structured data, a versatile record matching method for heterogeneous database linkage. We also developed a linkage system for scientific papers and researchers the usefulness of which we demonstrated using a nationwide academic content service provided by NII.
