| 摘 要： | 高考语文阅读理解问答相对普通阅读理解问答难度更大,问句抽象表述的理解需要更深层的语言分析技术,答案候选句抽取更注重与问句的关联分析,答案候选句排序更注重答案句之间的语义相关性。为此,该文提出借助框架语义匹配和框架语义关系抽取答案候选句,在排序时引入流形排序模型,通过答案句之间的框架语义相关度将排序分数进行传播,最终选取分数较高的Top-4作为答案句。在北京近12年高考语文阅读理解问答题上的准确率与召回率分别达到了53.65%与79.06%。 |

| Abstract: | Reading comprehension QA for Chinese College Entrance Examination is much more difficult than general reading comprehension QA in that it requires deeper linguistic analysis technology to understand the question, and the semantic correlation between the answers and questions. This paper proposes to extract the candidate answer sentences by frame semantic match and frame-frame semantic relation, and the manifold-ranking model are applied to propogate the frame semantic relevancy to decide the top-four candidate answers. The accuracy and recall on the college entrance examination of Beijing in recent twelve years is 53.65% and 79.06%, respectively. |
