From University Video Communications' catalog:"The ability to gain access to information stored in databases by expressing a request in natural language is desirable, but not widely available for serious applications. After weighing the advantages of natural language vs. formal query languages, we review some of the reasons why NL interfaces are difficult to develop for serious applications. In our work on natural language understanding at Hewlett-Packard Labs, we are addressing these challenges, and are also working to develop metrics for evaluating both our progress and that of our colleagues in the field. We present one such set of metrics that is used to track our progress in coverage of English grammatical constructions, and we outline a more general framework for measuring the quality of NL interfaces for database query."
