Extending the E-R Concepts to Capture Natural Language Semantics for Database Access

[[abstract]]Entity-relationship (E-R) concepts are extended to capture natural language semantics and develop a logical form to represent natural language queries. The logical form can be efficiently transformed into relational algebra for query execution. The whole process provides a clear and natural framework for processing natural language queries to retrieve data from database systems[[fileno]]2030208030097[[department]]資訊工程學
