A measure of semantic relatedness for resolving ambiguities in natural language database requests

摘要

Semantic relatedness measures based on distance between objects in the database schema have previously been used for solving a variety of natural language understanding problems including word sense disambiguation, resolution of semantic ambiguities, and attachment of post noun modifiers. The use of cardinality values which are usually recorded as part of the process of designing the database schema is proposed for solving some of the given problems as they arise in natural language database requests. The cardinalities provide a richer source of knowledge for resolving ambiguities and a semantics for understanding previous semantic relatedness measures.
