The Research On Elementary Mathematics Probability And Statistical Corpus Building

For the computer lack of corpus support in elementary mathematics problem solving like people,this paper analyzes the university entrance exam questions,review questions and the relevant knowledge of 2008-2014,aimed at completing the classification and characterization of elementary mathematical probability and statistics problems solving like people,the construction and description of problem solving rules,and the construction and application of corpus.This study not only provides support for the realization of the computer to solve the college entrance examination questions of probability and statistics like people,but also can provide the material for the relevant research of probability and statistics.The research contents of this paper mainly consists of three parts.First,the classification and representation of probability and statistics in elementary mathematics.The computer collects 432 college entrance examination questions which about probability and statistics in total.It based on the knowledge structure of probability and statistics first,then using it's mind maps to form a reliable knowledge system and establish the index table.Thus it can first label all the knowledge points of each college entrance examination questions.Then it can count and analyze all kinds of knowledge points.Next it can select two types of knowledge points as representation from the perspective of difficulty level and using times.Finally it can capture information from the relevant conditions and achieve the purpose of "comprehension".Second,the construction and description of solving rules in elementary mathematical probability and ststistics.According to the previous classification system of knowledge,the computer make the detailed regulations of problem solving based on the main knowledge points.In addition to the stratified sampling and classical subscheme questions,the other knowledge points will also be selected as the research object.For example,systematic sampling,frequency distribution histogram,classical probability and independent events and so on.And then,the computer will storage these problem solving rules as Prolog language to achieve the function of "automatic solve".Third,the construction and application of corpus in elementary mathematical probability and statistics.The corpus system which based on web technology,mainly provide a function of searching and displaying the questions.The forrground provide the function of fuzzy input of test information,rapid processing and matching display.And the background is mainly provide the function of test information input,import and management.Through the database design and function to achieve a detailed description of the role of this system,so that the computer can achieve the function of "gathering examination questions".The construction of corpus in elementary mathematical probability and statistics in this paper contains three aspects.First,the construction and storge of solving rules.Second,the construction of knowledge classification system.Third,the construction of material database.And this is different from the construction of corpus in literarure,especially on the principles and methods.Through the construction of the corpus,the computer can extract relevant questions and show their detailed information.And through automatic tagging tools to characterize the question of the topic and formulate the rules of Prolog,the computer can realize the solving process like people "gathering the examination questions"--"identifying the examination questions"--"solving the examination questions".
