USING DEPENDENCY PATHS FOR ANSWERING DEFINITION QUESTIONS ON THE WEB
Alejandro Figueroa, John Atkinson · 2009
This work presents a new approach to automatically answer definition questions from the Web. This approach learns n-gram language models from lexicalised dependency paths taken from abstracts provided by Wikipedia and uses context information to identify candidate descriptive sentences containing target answers. Results using a prototype of the model showed the effectiveness of lexicalised dependency paths as salient indicators for the presence of definitions in natural language texts.
