Understanding User’s Interests in NoSQL Databases in Stack Overflow

Abstract

NoSQL (Not only SQL) has gained popularity with emerging demands of scalable database with big data. Despite the great interest of users toward NoSQL technology, an attempt to analyze how the actual users react to NoSQL has not been made yet. Thus, the present work utilizes question-answer data acquired from Stack Overflow, a question and answer site that works as a large knowledge repository to understand how people perceive NoSQL technology. To this end, LDA topic modeling techniques are used to find out the trend of NoSQL databases. In addition, we proposed topic discrimination value in attempt to find topics that distinguish each NoSQL databases.
