基于LDA的信息资源挖掘与可视化研究
Research on Information Resources Mining and Visualization Based on LDA
摘要
Abstract
LDA is a probabilistic model for extracting topics from document resources, and it is usually effective for extracting topics from documents. Archival information resources are of high utilization value, but there are problems such as fragmentation and insufficient construction. Based on this, this paper applies LDA, clustering and hierarchical space construction technology to the construction of archival information resources, and conducts an empirical study. From the experimental results, the application of LDA to the construction of archival information resources can excavate the hidden connections between resources, clarify the hierarchy of resources, and contribute to the visual display of information resources.关键词
