Soojong Lim, Changki Lee, Myoung-Gil Jang · 2005
This paper presents a hybrid model for restoring an elided entry word for en-cyclopedia QA system. In Korean en-cyclopedia, an entry word is frequently omitted in a sentence. If the QA system uses a sentence without an entry word, it cannot provide a right answer. For resolving this problem, we combine a rule-based approach with Maximum Entropy model to use the merit of each approach. A rule-based approach uses caseframes and sense classes. The re-sult shows that combined approach gives a 20 % increase over our baseline. 1
