基于通用信息抽取模型的年鉴大事记知识图谱构建研究——以林业大事记知识图谱为例

Research on the Construction of Knowledge Graph of Yearbook Memorabilia Based on Unified Information Extraction Model: Take Forestry Memorabilia Knowledge Graph as an Example

针对大事记数据的特点,以及各行业对于大事记的信息化需求,本文尝试提出一种利用知识图谱来整理大事记中的信息的方法,从而有效抽取领域年鉴大事记中的多元主体,厘清主体间复杂关系,并用于查阅及宣传工作。首先,根据大事记中各类事件的特点,进行事件分类和概念建模,从整体的角度,对大事记的信息化处理方案进行设计;其次,对知识图谱进行顶层设计,选取通用信息抽取模型进行信息抽取、知识图谱构建与存储的工作;最后,以《中国林业年鉴》的林业大事记部分为例,说明知识图谱的构建过程和应用。本文提出的知识图谱的构建过程和方法能够通过少量人工标注数据将大事记转化为结构化的知识库形式,便于高效便捷地检索大事记记录的事件信息,为挖掘大事记档案文本的价值提供了基础。

In view of the characteristics of memorabilia and the informatization needs of various industries,this paper tries to propose a method of using knowledge graph to organize the information in memorabilia,so as to effectively extract the multiple subjects in the yearbook of specific field,clarify the complex relationship between subjects,and use it for access and publicity work.Firstly,according to the characteristics of various events in memorabilia,event classification and conceptual modeling are carried out,and the information processing scheme of the memorabilia is designed from the overall perspective;then the top-level design of the knowledge map is carried out,and the unified information extraction model is selected for the work of information extraction,knowledge graph construction and storage;finally,the construction process and application of the knowledge graph are illustrated by taking the Chinese Forestry Memorabilia,which is a part of the China Forestry Yearbook,as an example.The proposed knowledge graph construction process and method can transform the memorabilia into a structured knowledge base through a small amount of manually annotated data,which facilitates the efficient and convenient retrieval of event information recorded in the memorabilia and provides a basis for mining the value of the archival texts of the memorabilia.
