Construction And Application Of Knowledge Map For Chinese Poetry In Primary And Secondary Schools

With the development of education informatization and wisdom,more and more emerging technologies have started to try to explore in the field of education and have been actively applied.In order to face the new era of intelligent education,the research and application of a number of emerging technologies,represented by knowledge graphs and deep learning,has become one of the main elements of basic science research in education.Education,as a means of knowledge expression and dissemination,is naturally and inextricably linked to knowledge mapping which can express the structure of knowledge.As an important part of Chinese education with rich cultural connotations and historical value,poetry is widely known for the profound significance it plays in cultural education and has always occupied a very important place in the learning content of language subjects in primary and secondary schools,where the learning of poetic knowledge lays the foundation for humanistic education.The learning,dissemination and expression of poetic knowledge has rarely been integrated with the development of emerging technologies such as knowledge mapping.In this paper,based on the study of the characteristics of learning poetry knowledge and the characteristics of identifying poetry knowledge entities in primary and secondary schools,a knowledge graph for language poetry in primary and secondary schools is constructed,and a query platform for the structured display of poetry knowledge in primary and secondary schools is designed and developed.The specific research of this paper is as follows.Firstly,this paper acquires and cleans the data of primary and secondary school language poetry and constructs a multi-source poetry corpus.Using secondary school language textbooks as reference samples,this paper uses web crawler tools to collect relevant subject information from poetry websites such as Baidu Encyclopedia,AncientPoetry.com and PoetryQuotes.com to obtain semi-structured data and unstructured text data of poetry knowledge.The data is supplemented with third-party databases to obtain part of the structured data related to poetry knowledge.Through data cleaning and analysis processing of the semi-structured,unstructured and structured poetry data,the construction of a multi-source primary and secondary school poetry corpus is completed.Then,this paper designs the general architecture of poetry knowledge graph construction by analysing and studying the characteristics of poetry query services and poetry knowledge entity recognition.The process of constructing the poetry knowledge graph for primary and secondary schools is divided into four parts:data acquisition,information extraction,knowledge storage and visualisation.The most crucial part,information extraction,is divided into three aspects:poetry knowledge entity identification,poetry attribute acquisition and poetry relationship identification.A two-way long and short-term memory network-conditional random field model is used to train the poetry corpus,and a network information wrapper and syntax-based analysis are employed to identify entities,relationships and attributes of the primary and secondary school poetry corpus.By disambiguating and aligning the identified poetry knowledge triads,the construction and acquisition of poetry knowledge graph triads for primary and secondary schools is completed.The data storage and visualisation of the poetry knowledge graph were realised based on the graph data Neo4j.Finally,based on the constructed poetry knowledge map for primary and secondary schools and the storage of poetry knowledge content by the graph database Neo4j,a query platform that can structurally display poetry knowle dge relations is designed and developed for application in teaching practice.The platform provides an entry point for poetry knowledge queries and supports the query of poetry knowledge entities,the structured display of query content and the structured graph display of knowledge,facilitating the learning of poetry knowledge.
