Handling Domain Specific Document Repositories for Application of Query Languages

摘要

Domain specific information is increasingly available on the Web in form of document repositories. In specialized domains such as agriculture, bio-medical sciences and health-care, this information is required by various domain experts. Health-care experts such as researchers and practitioners require it during health-care delivery and for educational purposes. These users differ from the Web users and database users. Most of the existing document repositories on the Web have alphabetical and keyword based searches. These are not sufficient for the expert users with precise and complex queries, who require in-depth results within time constraints. Their information needs can be supported by providing user-level schema. Such a schema can support database-style high-level query languages over these repositories. Seeking specialized domain-specific information through queries is gaining importance. In this paper, a model for on-line document repositories is proposed. Queries can be performed with in-depth results. The model can be replicated to similarly structured document repositories in any given domain.
