Grammar-Based Automatic Extraction of Definitions

This paper presents part of our work in the LT4eL project [1] regarding the grammar developed by the Romanian team in order to extract definitions from texts. Some qualitative results come in order to evaluate our grammar rules. Among the applications of this kind of grammar we will discuss the possible inclusion of the grammar rules into a question answering system in order to extract answers for definition type questions. Another possible usage of those rules envisages the extraction of supplementary knowledge from linguistic resources like Wikipedia. The benefits of such an extra-knowledge resource are evident in textual entailment systems, where some resources like WordNet, Acronyms database or Dirt cannot cover all the requirements of the system. Keywords Definition Extraction, Question Answering, Textual Entailment.
