Semantic Analysis of Natural Language Queries for an Object Oriented Database (Report‪)‬

1. Introduction On the earliest and most widely studied areas of natural language processing is the development of a Natural language interfaces to databases (NLIDB) [1-7]... A NLIDB allows users to input a query in a natural language such rather than in a formal query language and in conceptual terms particular to their understanding of the database application domain. In most works, the underlying database is assumed to be relational. In our work, we are interested in building a NLI for an object-oriented database (OODB). Unfortunately, the relational model and the object model are fundamentally different. Relational database (RDB) systems are based on two-dimensional tables in which each item appears as a row. Relationships among the data are expressed by comparing the values stored in theses tables. The object model is based on the tight integration of code and data, flexible data types, hierarchical relationships among data types, and references [8].
