Update Request Comments in Stack Overflow Answer Posts

Comments play an important role in updating Stack Overflow (SO) posts. They are used to point out a problem (e.g., obsolete answer and buggy code) in a SO answer or ask for more details about a proposed answer. We refer to this type of comment as update request comments (URCs), which may trigger an update to the answer post and thus improve its quality. We manually analyzed a set of 384 sampled SO answer posts and their associated 1,221 comments to investigate the prevalence of URCs and how URCs are addressed. We have provided three level of annotation: 1- If it is a URC, 2- For URCs, where is it addressed, i.e., in the next comments, in the post body, or both. 3- For URCs that are addressed by the following comments, which comment addresses it.

评论在更新堆栈溢出（Stack Overflow, SO）帖子中发挥着关键作用。此类评论可用于指出SO回答中的问题（例如过时的回答、存在缺陷的代码），或请求补充有关所提出回答的更多细节。我们将这类评论称为更新请求评论（Update Request Comments, URCs），这类评论可能会触发回答帖子的更新，进而提升回答质量。我们手动分析了384个采样的SO回答帖子及其关联的1221条评论，以探究更新请求评论的普遍性，以及这类评论的处理方式。本次标注共设三个层级：1. 判定目标评论是否为更新请求评论；2. 针对更新请求评论，明确其处理位置，即在下一条评论中、在帖子正文中，或两者兼具；3. 针对被后续评论处理的更新请求评论，确定完成该处理的具体评论。
