| 摘 要： | 本文提出了一种基于浅层语义的FAQ检索模型.该模型以自然语言为接口,利用"知网"和农业本体,首先从用户输入中抽取农业领域概念词,然后根据这些概念词从系统数据库中检索出一个候选QA对的小集合,通过计算输入问句与候选QA对的语义相似度,选择一些与输入问句接近的问题,以及对应的答案返给用户.

| Abstract: | A FAQ Search model based on the latent semantic was presented.The model provides a natural language interface,a small pool of the candidate question-answering pairs retrieved from the system for the follow-up work according to the concept of the agriculture domain extracted from user input.The probabilities estimated from several parts are integrated and used to choose the most likely answer for the input query. |

| Keywords: | FAQ retrieval ontology candidate question-answering pairs |
