The Impact Of Natural Language Access On Database Design And Implementation
نویسنده
چکیده
This is perhaps the broadest category. Among Ehe particular demands of natural language access are: treatment of lexicon and lexical ambiguities; use of parenthetical expressions which may require simultaneous update and query; support for the generation of natural language responses; storage of discourse information; representation of text structure models; accurate processing of natural language updates; and other interactions that, though not unique to natural language access, have special problems in that context, such as natural language queries to dynamic databases requiring natural language statements of alerting conditions, or answering "metaquestions" questions about structure. Current work in all these areas suggests the need to augment data models in particular ways.

متن کاملExtending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths
Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...
متن کاملSemantic Analysis of Natural Language Queries Using Domain Ontology for Information Access from Database
This paper describes a method for semantic analysis of natural language queries for Natural Language Interface to Database (NLIDB) using domain ontology. Implementation of NLIDB for serious applications like railway inquiry, airway inquiry, corporate or government call centers requires higher precision. This can be achieved by increasing role of language knowledge and domain knowledge at semant...
