Supplemented by experts answer,an automatic question-answering system is developed based on the database of agricultual operative technology information, natural language understanding,the retrieval model of improved VSM and efficiency optimization. The system has features on the simple way of inquiry, accurate replies, professional answers and high satisfaction.It is better able to meet the farmers’ need of production techniques.
