Popis: | This paper presents a study on analyzing questions in legal domain for Vietnamese language, which is an important step in building an automated question answering system for the domain. We focus on questions about transportation law — the law with arguably the largest number of violations and thus is the most asked about. Given a legal question in natural language, our goal is to extract important information such as Type of Vehicle, Action of Vehicle, Location, and Question Type. We model the question analysis task as a sequence labeling problem and present a CRF-based method to deal with it. Experimental results on a corpus consisting of 1678 Vietnamese questions show that our method can extract 16 types of information with high precision and recall. |
