Natural Language Query Filtration in the Conceptual Query Language
نویسندگان
چکیده
Natural language (NL) interfaces for DB query formulation have always been recognized as a much needed enhancement for end-users. Poor performances with earlier NL systems had led to a lull in research in this field. However, latter-day experiments and systems appear to be sufficiently more promising to warrant continued and further research in this area. This study proposes an experimental query interface that filters NL query statements for search predicates that are derived from constructs on conceptual schemas, thereby avoiding the computational difficulty with full-fledged NL parsing. A prototype of the CQL exists as a frontend to an ORACLE relational DBMS.

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 کاملSPATIAL KNOWLEDGE EXTRACTION FROM GEOGRAPHICAL DATABASES An approach based on the Controlled English Query Language Geo-Q and Conceptual Graphs
Conceptualizing spatial relations through natural language seems to be closer to the model humans adopt for spatial reasoning. Controlled languages, which are subsets of natural ones, could be used in order to overcome the difficulties that emanate from the required experience in programming languages. In this paper, we propose a methodology in which questions are expressed in a new controlled ...

Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...

متن کاملExtending the UML Concepts to Transform Natural Language Queries with Fuzzy Semantics into SQL
Database applications tend toward getting more versatile and broader to comply with the expansion of various organizations. However, naïve users usually suffer from accessing data arbitrarily by using formal query languages. Therefore, we believe that accessing databases using natural language constructs will become a popular interface in the future. The concept of Object-Oriented modeling make...
