中文摘要:
      本文针对农业问答系统中方式型问句的答案抽取,提出了利用语义文摘方式从相关文档中抽取方式型问句的答案? 首先,由于同一类问句的答案中包含大量相同词语,利用一个主题词选择方式型问题主题段落;然后基于语义摘要抽取候选答案;最后,采用计算问句和答案中谓语动词的语义相似度对答案排序? 实验结果表明,本文基于语义摘要的农业方式型问句答案抽取方法的有效性,能够满足用户的需求?
英文摘要:
      Aiming at searching the answer of how to questions in the agricultural question answering system, the answer extraction based on the semantic summary is proposed in this paper. Firstly, because there are the many same words in the answers of the same type how to questions, we used the subject words to select the subject paragraph of the question. Then, the candidate answers were extracted using the semantic summary. Finally, the answers were sorted by the semantic similarity between the verbs of the question and the answers. The experimental results show that the method is efficient and can meet the need of the users.
