NLP-Reduce: A "naive" but Domain-independent Natural Language Interface for Querying Ontologies
NLP-Reduce is a natural language query interface that allows its users to enter full English questions, sentence fragments, and keywords. It processes queries a s bag of words and only employs a reduced set of natural language processing techniques, such as stemming and synonym expansion.
Dependencies between word or phrases in the queries are only identified by the relationships that exit between the elements in a queries knowledge base. This weakness is also its major strength, as it is completely portable and robust to ungrammatical or deficient input.
