Evolution of Stack Overflow Discussions Using Sentimental Analysis on Comments in Stack Overflow Posts Presented by Norbert Eke and Saraj Manes
Motivation ● SOTorrent 2018 : Reconstructing and Analyzing the Evolution of Stack Overflow Posts.
Motivation ● SOTorrent 2018 : Time Span between edits. ● “If we focus on the comments, we see that 64.4% of them happened on a day where the post had either been created or edited.”
Motivation Questions: Is there any relation between Comments and edits? Does one cause the other? Do edits cause more number of comments OR Do comments lead to edits?
Our Previous Work How Often and What StackOverflow Posts Do Developers Reference in Their GitHub Projects? ● What type of posts are most popular/referred in GitHub projects ● How many versions for referred posts
Data Selection ● Initial data set is same as from our previous paper/work (21k SO Posts) ● Further, selection is based on following characteristics: ○ Post should be an accepted Answer on SO ○ Post should have been edited at least 5 times ○ Post should have at least 10 comments ● Resultant Data Set: ○ 684 SO Posts, referred in GH Projects ○ 14283 number of comments, ~21 average
Research Questions RQ1: For all edited posts on SO, what is the overall sentiment of comments w.r.t to edit timeline ? Does the overall sentiment in discussions improve with edits? RQ2: If quality of SO answers improves with edits, does the sentiment of comments indicate this trend? RQ3: How does sentiment of SO discussions vary with topics? (RQ4): Knowing if a post is reliable/stable (unlikely to be edited in future) is important for software engineers. How could it be detected if a post will likely be edited in the future ?
