【摘要】：随着教育信息化的发展,教育已经进入了智能化的阶段。许多专家学者开始致力于研究类人解题器在教育领域的应用。但是,由于类人解题器涉及的关键技术:自然语言的理解技术与解题的类人推理技术等目前仍是世界上的难题,所以对解题器的研究还处于初步阶段。国内外对类人解题器的研究大多数是针对于数学学科的,比如几何解题系统、代数计算题智能解题器等,在物理学科方面,类人解题器的研究在世界范围内还是比较少的。物理学科类人解题器的开发还不够完善,开发出来的解题系统大多也只是能够解决系统设定好的物理题目或者需要人工手动进行解题,并没有完全实现"类人化"。在开发物理类人解题器的过程中,主要存在的技术问题有:物理题目的自然语言理解、解题过程的推理等。考虑到物理学科自身的独特性,本文选取了初中物理中较简单和基础的匀速直线运动类的计算题作为解题对象,初步对物理解题器进行了研究与设计。主要做了以下几项工作:(1)对初中物理匀速直线类运动计算题类人解题器的国内外研究现状以及相关理论进行了研究;(2)对类人解题器的相关技术进行了研究,包括:初中物理匀速直线类计算题知识库的构建技术、题目自然语言理解技术、解题自动推理技术等;(3)对初中物理中匀速直线类运动的一步求解计算题的类人解题器进行了设计与开发,包括:利用分词工具对题目分析,并对问题建模,建立方案库、模型库,对物理问题进行推理求解等。本文最后实现的系统能够帮助学生解答初中一步匀速直线类物理计算题,并且能够给出问题的类型、解题步骤与方法提示,对学生的自主学习有一定帮助。
[Abstract]:With the development of educational information, education has entered the intelligent stage. Many experts and scholars began to study human problem solvers in the field of education application. However, as the key technology of class solver involves: natural language understanding technology and problem solving class reasoning technology is still the world's problems so, research on the solver is still in the preliminary stage. Research on the type of problem solver at home and abroad for most of mathematics, such as algebraic geometry problem solving system, intelligent calculation problem solver, in physics, the research category of problem solver in the world is still relatively small. The development of physics the subject class solver is still not perfect, solving system developed mostly just to solve physical problems or need to set a good system manual and problem solving, not fully realized "Humanization". In the process of development of physics class of problem solver, the main technical problems are: natural language understanding of the physics problem solving process, reasoning and so on. Considering the uniqueness of physics itself, this paper selects the calculation problems in junior high school physics is relatively simple and the basis of uniform linear motion such as the object of physical problem solving, preliminary solver is studied and designed. The main work can be summarized as follows: (1) the calculation problem solver of the junior middle school physics class of uniform linear motion of the research situation at home and abroad are analyzed; (2) the relevant technology class solver is studied, including junior high school physics class uniform linear calculation problem of knowledge base construction technology, the topic of natural language understanding technology, solving automatic reasoning technology; (3) for the uniform linear motion in the junior middle school physics class step to solve the problem of calculation class problem solving For the design and development of the subject, including: analysis of the use of segmentation tool, and the problem of modeling, establish scheme database, model base, reasoning on physical problems. The system implemented in this thesis can help the students to answer questions in junior middle school are calculated step by uniform linear physics, and can be given the type of problem solving, TIPS procedures and methods of students' autonomous learning some help.
