Automatic Eztraction of Definitions
The task of definition extraction aims to acquire definitions of terms from texts. This task is a subtask of terminology extraction, ontology construction, semantic relation learning, and question answering and so on. This paper presents a bootstrapping approach to automatic extracting definitions of domain-specific terms from unannotated Chinese free texts. Experimental results in three domains of computer, military, and archaeology show effectiveness of our algorithm. As an application of definition extraction, definitions identified by our method have been used to answer factual questions in a question answering system.
