摘要

主题模型已被广泛用于发现文档集合中的隐藏主题。在本文中，我们建议探讨两种不同类型的关系信息，即文档关系和概念关系的作用。虽然利用文献网络可以显著提高主题连贯性，但概念及其关系的引入并不会在数量和质量上影响结果。

Which Matters Most? Comparing the Impact of Concept and Document Relationships in Topic Models

Topic models have been widely used to discover hidden topics in a collection of documents. In this paper, we propose to investigate the role of two different types of relational information, i.e. document relationships and concept relationships. While exploiting the document network significantly improves topic coherence, the introduction of concepts and their relationships does not influence the results both quantitatively and qualitatively.
