The Design And Implementation Of College Entrance Examination Geography Problem Automatic Solving System Based Reasoning

“Open Field Knowledge Association?Reasoning and Retrieve Key Technologies”,one of the National High Technology Research and Development Program("863" Program),aims at implementing auto question answering on the college entrance examinations of geography problem which contains a series of geography reasoning questions to answering.The geography problem has some feature which contains the standard question forms,the evidencesof answer contained in the question stem and so on.The representative part of geography problem is the development status geography problem,which accounts for the 20 percent in the geography problem.This thesis analysis the college entrance examination questions over the years.Summarizing the information about this short answer question?the expression model of problem and the extraction of problem content.We proposed a design and implemention programm of the geography problem to provide reference for relevant rearch.The main work of this thesis is about : 1)analysis the beijing geography short answer question over years and find the question type?solving process and answer pattern;2)design the question understanding model of the development status type geography problem and design the Question Information Extraction model(QSIRM)of the outside knowledge;3)design and implement the problem explanation algorithmn based on AMR(abstract Meaning representation)and ASP text knowledge representation model;4)design and implement a knowledge expansion method for knowledge graph and outer query database;5)design and implement one kind of method for answer generated 6)design and implement a QA system for the college entrance examinations of geography problem named AMRR.This thesis uses the development status short answer question from 2010 to 2016 as test case,and the result shows that AMRR is useful to the college entrance examination questions.
