Abstract
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
