Cooperative Query Answering Using Multiple Layered Databases
نویسندگان
چکیده
How can a real-estate agent respond to inquiries quickly and intelligently? Thètrick' could be using a simple table to brieey outline the general information and a complete book to reference the details. Such a method can be generalized to the construction of a multiple layered database (MLDB), a useful database organization technique for cooperative query answering, database browsing, query optimization and querying cooperative information systems. In this paper, we study the construction of MLDBs using generalization and knowledge discovery techniques and the application of MLDBs to cooperative/intelligent query answering in database systems.

متن کاملCooperative Answering through Controlled Query Relaxation
AS KNOWLEDGE STORAGE SYStems grow in size and complexity, it becomes unreasonable to expect that users always know enough about the data and how the data are organized to construct accurate and useful queries. Even when a system has syntactic utilities for building queries, users continue to compose queries that contain misconceptions, are too general, or are bound to fail. Cooperative-answerin...
متن کاملCooperative Query Processing via Knowledge Abstraction and Query Relaxation
As database users adopt a query language to obtain information from a database, a more intelligent query answering system is increasingly needed that cooperates with the users to provide informative responses by understanding the intent behind a query. The effectiveness of decision support would improve significantly if the query answering system returned approximate answers rather than a null ...
