Assigning defects is a task that is not so much fun. Companies need to do that, but the persons who do it often change as the task is quite labor intensive and tiresome. There is, of course, a significant body of research about this and here is one example of it.

What is interesting in this article is that the authors use temporal data about the defect reports to assign teams. From the abstract: “In this article, we describe a new BA approach that relies on two key intuitions. Similar to traditional BA methods, our method constructs the expertise profile of project developers, based on the textual elements of the bugs they have fixed in the past; unlike traditional methods, however, our method considers only the programming keywords in these bug descriptions, relying on Stack Overflow as the vocabulary for these keywords. The second key intuition of our method is that recent expertise is more relevant than past expertise, which is why our method weighs the relevance of a developer’s expertise based on how recently they have fixed a bug with keywords similar to the bug at hand.

The method uses text similarity measures to match defects and performs better than existing methods based on the meta-parameters. What it means in practice is that the only thing that is needed is the actual defect description, or actually a failure report in order to make the predictions.

Very interesting work to apply, it seems that the entry level is not that high for new companies.
