Query Processing for Partial Information Databases in QUIXOTE
نویسندگان
چکیده
In advanced knowledge processing, partial information plays an important role in coping with complex data and knowledge. To handle such information, we developed the knowledge representation language (which may be regarded as a deductive object-oriented database language) QUIXOT E. The language has the features of both logic and object-orientation concepts, as well as database features. In this paper, we introduce the query processing mechanism for partial information databases in QUIXOT E, as a tool for e ective data processing, taking the example of legal reasoning, and show its applicability to many applications in arti cial intelligence.

Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...

Deductive Database systems are designed based on a logical data model. Data (as opposed to Relational Databases Management System (RDBMS) in which data stored in tables) are saved as facts in a Deductive Database system. Datalog Educational System (DES) is a Deductive Database system that Datalog mode is the default mode in this system. It can extract data to use outer joins with three query la...
متن کاملAn Effective Path-aware Approach for Keyword Search over Data Graphs
Abstract—Keyword Search is known as a user-friendly alternative for structured languages to retrieve information from graph-structured data. Efficient retrieving of relevant answers to a keyword query and effective ranking of these answers according to their relevance are two main challenges in the keyword search over graph-structured data. In this paper, a novel scoring function is proposed, w...
