How Developers and Tools Categorize Sentiment in Stack Overflow Questions - A Pilot Study

The paper presents results from a pilot questionnaire-based study on ten Stack Overflow (SO) questions. Eleven developers were tasked with determining if the SO question sentiment was positive, negative or neutral. The results from the questionnaire indicate that developers mostly rated the sentiment of SO questions as neutral, stating that they received little or no emotional feedback from the questions. Tools that were designed to analyze Software Engineering related texts (SentiStrength-SE, SentiCR, and Senti4SD) were on average more closely aligned with developer ratings for a majority of the questions than general purpose tools for detecting SO question sentiment. We discuss cases where tools and developer sentiment differ along with implications of the results. Overall, the sentiment tool output on the question title and body is more aligned with the developer rating than just the title alone. Since SO is a very common medium of technical exchange, we also report that adding code snippets, short titles, and multiple tags were top three features developers prefer in SO questions in order for it to be answered quickly.
