![]() Rodrigo reproduced both works, which resulted in a paper published at SANER’2018 in Italy.ĭuring that conference, Rodrigo was introduced to one of the Dupe authors, Professor Chanchal K. After a preliminary literature review, Rodrigo came across two previous works, DupPredictor and Dupe, that detect duplicate questions on Stack Overflow. He decided to investigate duplications in Stack Overflow under Professor Marcelo de Almeida Maia’s supervision. The backstory for this fascinating service begins in 2017, when Rodrigo Fernandes, a PhD student in computer science at The University of Uberlandia in Brazil, was looking for a thesis topic. This service takes the description of a programming task as a query and then provides relevant, comprehensive programming solutions containing both code snippets and their succinct explanations. Other times they find a great explanation about how one might solve the problem, but not the actual code.Įarlier this year, a team of computer science researchers published a paper with a novel solution to this problem: CROKAGE – the Crowd Knowledge Answer Generator. A lot of the time they find the relevant code, but don’t find a clear explanation of how to implement it. ![]() Software developers searching for answers might use natural language – “How do I insert an element array in a specific position?” – or they might choose a few important keywords relevant to the programming task at hand and use those as their query with the hope that the search engine would return the relevant solutions. Some use the internal SO search feature while others use search engines such as Google or Bing, narrowing down the search to the domain. When a developer is stuck on a coding problem, they search through this vast trove of information to see if a solution to their particular conundrum has already been offered. ![]() Community members have contributed more than 18 million questions and 27 million answers. One of the most powerful attributes of Stack Overflow (SO) is the accumulation of developers’ knowledge over time.
