基于LDA-BERT模型的智慧图书馆主题演化研究

Research on Theme Evolution of Smart Library Based on LDA-BERT Model

近年来,图书馆正不断朝“智慧化”方向迈进,智慧图书馆也逐渐走进研究者的视野。本文将LDA主题模型和BERT模型相结合,构建主题相似性测度模型,量化智慧图书馆领域主题之间的关联关系,并以此为基础绘制主题演化图谱,分析中外智慧图书馆领域研究主题的演化趋势,探究中外研究的异同。基于主题演化图谱可以看出,智慧图书馆领域的研究主要聚焦于智慧图书馆理论研究、智慧图书馆服务、智慧图书馆技术与实践研究、智慧图书馆管理、图书馆资源获取与知识产权等5个领域。其中,中文研究侧重智慧图书馆服务;外文研究则侧重图书馆的资源获取与管理。

In recent years,the library is constantly moving towards the“intelligent”,the smart library has gradually come into the vision of researchers.This paper combines the LDA topic model and BERT model,builds a topic similarity measurement model,quantifies the correlation between topics in the field of smart library,and draws the topic evolution map based on this,analyzes the evolution trend of topics in the field of smart library at home and abroad,and explores the similarities and differences between Chinese and foreign studies.Based on the theme evolution graph,we can see that the research in the field of smart library mainly focuses on the theory research of smart library,smart library service,smart library technology and practice research,smart library management,library resource acquisition and intellectual property rights.Among them,Chinese research focuses on the smart library service;Foreign language studies focus on the acquisition and management of library resources.
