Cooperative Query Answering for Approximate Answers with Nearness Measure in Hierarchical Structure Information Systems
COOPERATIVE QUERY ANSWERING FOR APPROXIMATE ANSWERS WITH NEARNESS MEASURE IN HIERARCHICAL STRUCTURE INFORMATION SYSTEMS Thanit Puthpongsiriporn, Ph.D. University of Pittsburgh Cooperative query answering for approximate answers has been utilized in various problem domains. Many challenges in manufacturing information retrieval, such as: classifying parts into families in group technology implem...
متن کاملN 93 - 32153 Cooperative Answers in Database Systems
A major concern of researchers who seek to improve human-computer communication involves how to move beyond literal interpretations of queries to a level of responsiveness that takes the user's misconceptions, expectations, desires, and interests into consideration. At Maryland, we are investigating how to better meet a user's needs within the framework of the cooperative answering system of Ga...
متن کاملAdvanced Relaxation for Cooperative Question Answering
Advanced reasoning for Question Answering (QA) systems, as described in a recent roadmap (http://www-nlpir.nist.gov/projects/duc/papers/qa.Roadmappaper_v2.doc), raises new challenges since answers are not only directly extracted from written texts or structured databases but also constructed via several forms of reasoning in order to generate answer explanations and justifications. These system...
متن کاملCooperative Explanation in Deductive Databases
1 Motivation As knowledge-based systems become more complex in design and capability, their ability to communicate with their users must keep pace. Otherwise, the typical user will be unable to take full advantage of the sophisticated tools that modern knowledge base technology can and will make available. A major concern of researchers who seek to improve human-computer communication involves ...
متن کاملAn Integrated Query Relaxation Approach Adopting Data Abstraction and Fuzzy Relation
This paper proposes a cooperative query answering approach that relaxes query conditions to provide approximate answers by utilizing similarity relationships between data values. The proposed fuzzy abstraction hierarchy (FAH) represents a similarity relationship based on the integrated notion of data abstraction and fuzzy relations. Based on FAH, the authors develop query relaxation operators l...
