C-Phrase: A System for Building Robust Natural Language Interfaces to Databases
Umeå University, Sweden .ORCID iD: 0000-0001-7088-3070
2010 (English)In: Data & Knowledge Engineering, ISSN 0169-023X, E-ISSN 1872-6933, Vol. 69, no 3, 290-302 p.Article in journal (Refereed) Published
Abstract [en]

This article presents C-PHRASE, a natural language interface system that can be configured by normal, non-specialized, web-based technical teams. C-PHRASE models queries in an extended version of Codd's tuple calculus and uses synchronous context-free grammars with lambda-express ions to represent semantic grammars. Given an arbitrary relational database, authors rapidly build an NLI using what we term the narm-tailor-define protocol. We present a small study demonstrating the effectiveness of this approach for the CEO corpus and we introduce the evaluation metric of willingness that complements the standard metrics of precision and recall. However our true evaluation comes as we open-source C-PHRASE.
