随着便携式设备的日益普及和社区问答 (cQA) 网站的普及，用户可以无缝地发布和回答许多问题。为了有效组织信息以实现精准推荐和轻松搜索，这些平台要求用户为他们提出的问题选择主题。然而，由于经验有限，某些用户未能为他们的问题选择合适的主题。因此，自动问题标记成为 cQA 站点的一个紧迫而重要的问题，但由于以下挑战，它并非微不足道。一方面，有大量且有意义的主题可供使用，但尚未在 cQA 站点中使用；如何对它们进行建模并将其标记到相关问题是一个极具挑战性的问题。另一方面，cQA 站点中的相关主题可以组织成有向无环图。有鉴于此，如何利用主题之间的关系来增强……。

On the other hand, related topics in the cQA sites may be organized into a directed acyclic graph. In light of this, how to exploit relations among topics to enhance their ….
