Database Oriented Chart Parsing

We introduce the notion of parsing and translation using Database technology. The framework focuses on the notion of “Database Oriented parsing”. We describe the basic notion of linguistic representation using relational tables in SQL and we specify a set of operators on these tables for parsing and translation. The framework provides a flexible mechanism for modeling cross linguistic information about different languages in terms of relations and attributes. We are applying the model for parsing and translation of French sentences into English. In our work all the grammatical relations are specified as relations in SQL and constraints on word order are also defined in terms of relations. The work suggests a flexible multi-lingual approach to grammatical modeling and parsing.
