This project developed a tool to assist scholars in identifying and selecting resources from within a Digital Library Corpus. Current access to this resource is available via text-based search in fulltext and metadata.
Our Capisco System analyzes documents by the semantics of their content. Traditional access to the digitized document collections is available primarily via string-based search in the documents’ full-text and metadata. Such a text-based search identifies documents purely according to lexicographical analysis. Most research questions and areas of scholarly interest, however, can rarely be described by simple textual keywords and instead, they encompass larger concepts.
Capisco avoids the need for complete semantic document markup using ontologies by leveraging an automatically generated Concept-in-Context (CiC) network. The network is seeded by a priori analysis of Wikipedia texts and identification of semantic metadata, implementing a annotate-to-wikipedia (A2W) approach. Our Capisco system disambiguates the semantics of terms in the documents by their semantics and context and identifies the relevant CiC concepts.
We further developed means to harness the results of our developed semantic analysis and disambiguation, while retaining the existing keyword-based search and lexicographic index. We engineer this so the output of semantic analysis (performed off-line) is suitable for import directly into existing digital library metadata and index structures, and thus incorporated without the need for architecture modifications.
Capisco was developed in collaboration with the HathiTrust Research Center.
