摘要

A system for natural language (NL) analyzis is provided which comprises apparatus and method. It has the capability to analyze NL expressions and to resolve ambiguities and present them to the user for verification of correct interpretation. The invention is based on a language independent model of the contents of a data base. The model contains records of information defining entity types and relations between such entity types. The model is created (customizing the system) by the user, and is stored as a conceptual schema. The entities of the schema are linked or connected to natural language terms in a vocabulary. The entities represent objects in the data base, and there is a link or connection between the entities and those objects of the data base. The actual analysis of NL expressions is performed by a Natural Language Engine (NLE) in cooperation with an Analysis Grammar and the schema. The analysis results in an intermediate, language independent logic form representation of the input, which is paraphrased back to NL for verification, and if the input is a query, there is a translation into a query language such as SQL.
