The Research And Implemention Of The Sub-human Judgment In The Junior High School Algebra Problem Based On The Rule Flow

With the progress of society and the development of information technology, the Internet is changing every aspect of our lives, all walks of life in the subversion of the traditional, toward the Internet model forward. From learning resources, shopping and contact details of the Internet, but now travel, meals and real estate of the Internet, our clothing, food, shelter, rows can rely on the Internet, can be resolved without leaving home. But the the education industry, the Internet is relatively slow, in recent years have done a lot of efforts in this area at home and abroad in recent years, but with little success, one reason is the cause of the education industry itself, more important is the slow development in the field of artificial intelligence, did not obtain the big breakthrough, because want to let the machine education, must let the machine is smart enough, let the machine with recognition, understanding and regeneration of human knowledge ability. This thesis is devoted to the research on the problem of the algebra problem in junior high school, which involves the formal representation of knowledge, the automatic reasoning of artificial intelligence, the definition and representation of the rule flow, the equivalence of knowledge, and the orientation of the wrong type. Research and build a junior high school algebra class people graders system, first on the basis of an understanding of the meaning of the questions in accordance with the rules defined flow automatically generate more richer standard answer form knowledge base; Secondly, students were sentenced to answer volume, a positive error in judgment after further identify the cause of the error to the students. The main research contents are as follows:1、Machine representation of algebraic knowledge. In this paper, we will study a kind of knowledge representation, which combines the algebra knowledge of junior middle school and the first order predicate logic as well as the Java class. It is convenient for computer to understand, transmit, store and regenerate.2、Automatic reasoning of artificial intelligence. The automatic reasoning of artificial intelligence is used to realize the automatic generation of the standard answer. It can generate as much as possible the complete standard answer, put in a knowledge base to store up, for the comparison of the student to answer with the standard answer.3、The definition and representation of regular flow. Rules flow definition and representation of, namely solving steps has order determined in junior high school algebra, each kind of questions are basic fixed solution, which needs combined with large data for various types of, to find the solution of the fixed and to define the order of execution of rules.4、Knowledge equivalence. Due to knowledge base impossible complete enough. In addition to comparison, we introduce the logic and computing to judge the equivalence of knowledge in the study of knowledge equivalence.5、Error type location. In addition to simple give students answers progressive judge right and wrong, this paper also study further give the wrong answer to the students find the cause of the error. So as to give the students the greatest help, let the students know where they are wrong, and avoid the next to continue to make mistakes.
