Modern Natural Language Interfaces to Databases: Composing Statistical Parsing with Semantic Tractability
نویسندگان
چکیده
Can we leverage the advances in statistical parsing over the last fifteen years to build more powerful “transportable” Natural Language Interfaces to Databases (NLIs)? To address this question, this paper reports on the PRECISE NLI, which uses a statistical parser as a “plug in”. The paper shows how a strong semantic model enables PRECISE to correct parser errors, and map from parsed questions to the corresponding SQL queries. We discuss the challenges of using statistical parsers to build databaseindependent NLIs, and report on experimental results with the benchmark ATIS data set where PRECISE achieves 94% accuracy.

PRECISE on ATIS: Semantic Tractability and Experimental Results
The need for Natural Language Interfaces to databases (NLIs) has become increasingly acute as more and more people access information through their web browsers, PDAs, and cell phones. Yet NLIs are only usable if they map natural language questions to SQL queries correctly — people are unwilling to trade reliable and predictable user interfaces for intelligent but unreliable ones. We describe a...
متن کاملIntegrating Statistical and Relational Learning for Semantic Parsing: Applications to Learning Natural Language Interfaces for Databases
The development of natural language interfaces (NLIs) for databases has been an interesting problem in natural language processing since the 70's. The need for NLIs has become more pronounced given the widespread access to complex databases now available through the Internet. However, such systems are diicult to build and must be tailored to each application. A current research topic involves u...
متن کاملLearning Semantic Parsers for Natural Language Understanding
For building question answering systems and natural language interfaces, semantic parsing has emerged as an important and powerful paradigm. Semantic parsers map natural language into logical forms, the classic representation for many important linguistic phenomena. The modern twist is that we are interested in learning semantic parsers from data, which introduces a new layer of statistical and...
