English Intelligent Question Answering System Based on elliptic fitting equation

Abstract The elliptic equation intelligent question answering system based on the is an device that combines natural language and data retrieval technology. Knowledge domains used for different purposes are divided into open restricted domains. In order to simplify existing knowledge of English intelligence answer algebra reduce efficiency questionnaire, a similar algorithm designed implemented in process answer, method distance ellipse switching adopted. experimental results show accuracy questionnaire questions described this paper 17% higher than general research answers, which confirms authenticity mentioned paper. not only provides accurate answers primary school students, but also plays important role cultivation skills secondary schools.
