Knowledge graph construction method for Tang poetry knowledge and Tang poetry knowledge question-answering system

Abstract

The invention provides a knowledge graph construction method for Tang poetry knowledge and a Tang poetry knowledge question-answering system. An ontology model of a Tang poetry knowledge graph is constructed by adopting a top-to-bottom and bottom-to-top combined method. Therefore, the constructed knowledge graph aiming at the Tang poetry knowledge has a more reasonable structure, and the definition of the ontology is richer, so that the completeness and accuracy of the knowledge graph can be ensured, and the Tang poetry knowledge graph which is higher in automation degree, more reasonable in ontology model and stronger in question and answer ability can be constructed. Therefore, the knowledge graph constructed based on the preset ontology structure has a more perfect structure, more accurate information and a more refined knowledge level. The poem entities in the entity objects are subjected to entity alignment and entity disambiguation, knowledge fusion of the poem entities is achieved, the redundancy of the knowledge graph can be reduced, knowledge conflicts can be avoided, and therefore the knowledge accuracy of the constructed knowledge graph for the Tang poem knowledge can be further guaranteed.

Description

technical field [0001] The present application relates to the technical field of data processing, and specifically relates to a method for constructing a knowledge map for knowledge of Tang poetry and a question-and-answer system for knowledge of Tang poetry. Background technique [0002] The achievements of ancient Chinese civilization are as brilliant as the stars, and the poetry of the Tang Dynasty (hereinafter referred to as "Tang poetry") is undoubtedly a bright pearl in the field of literature. As a treasure of the Chinese nation and a representative form of ancient Chinese literature, Tang poetry has an important historical status and literary and artistic value. [0003] In ancient times, the collation of Tang poetry was mainly to compile Tang poetry anthologies of various standards. According to the statistics of Sun Qin'an, a researcher at the Shanghai Academy of Social Sciences, in the book "Summary of Anthologies of Tang Poetry", from the Tang Dynasty to the Qin...

AI Technical Summary

Problems solved by technology

Taking "Tang Poetry Bieyuan" as an example, many Tang poems only have basic information such as title, author, and poem content, which shows that the degree of automatic construction of its knowledge graph is not high, and the automatic classification of Tang poetry themes and imagery and emotion have not been fully realized. extract

On the other hand, judging from the structure of the ontology model of the knowledge map, both of them center on poetry and poets, and only use imagery as the attribute of poetry, and do not store the relevant interpretations of imagery, and do not pay enough attention to imagery. Inconsistent features centered on imagery

At the same time, the platform supports fewer types of questions, and the accuracy of question and answer is not high
