Research On Commonsense Knowledge Base Construction For Understanding Word Problems In Probability And Statistics Of Elementary Mathematics

In order to solve the problem of the question of the problem of solving the problems in the course of the elementary mathematics,this paper is based on the probability and statistics of elementary Mathematics from 2004 to 2016, and after the thorough analysis of the subject, the concept of commonsense is put forward, and the commonsense features are analyzed and classified to use the appropriate representation of knowledge.Moreover, the XML tags corresponding to the classification are stored in commonsense,aiming at the classification, representation and storage of elementary mathematical probability and statistical knowledge. This paper also designs and realizes the commonsense annotation tool oriented to elementary mathematics probability and statistical knowledge, in order to provide help for the understanding of the subject matter of the elementary mathematics.The main content of this paper is divided into the following three aspects:(1) Characteristic analysis and classification of commonsense in specific domain.This study is based on the probability and statistics of elementary Mathematics from 2004 to 2016. In this paper,the author makes a thorough analysis on the task of solving the problem of understanding of the subject, and then defines the concept of commonsense in the field, summarizes the characteristics of commonsense in the field,and finally forms the classification.(2) The representation and storage of the commonsense of elementary mathematics probability and statistical problem. After collecting common knowledge by artificial means, this research is characterized by different knowledge representation for different kinds of commonsense. Finally, on the basis of previous work to form an effective XML tag to store common knowledge.(3) The realization and application of the commonsense annotation tool for elementary mathematics probability and statistical problem. This article designs and develops the commonsense annotation tool, its design idea is the topic carries on the word segmentation, the entity extraction, through the retrieval function browsing commonsense knowledge base common knowledge information, realizes the commonsense storehouse application, then assists the question understanding.In this paper, the research of commonsense library construction includes three aspects. The first is the feature analysis and classification of commonsense in specific domain. The second is the representation and storage of commonsense. The third is through the design and realization of commonsense annotation tools, it can extract the commonsense entities in the topic,and then tagging, forming a Commonsense knowledge base. Finally,it can help people to comprehend the meaning in the process of computer-aided solution.
