Classifying Software Problem Reports

In this presentation I will talk about the task of classifying problem reports, regarding the operation of a telephone switch software, to a fixed set of problem types. While the intention of using a problem type is to aid the software engineers in finding the cause of the problem, in practice, due to different reasons, many times the type is not assigned to a problem.

The talk will discuss issues surrounding modeling this task as a text classification problem, and decisions that one has to make regarding the nature of the training sets, and their impact on measures such as accuracy, precision, recall. We will present some of the results obtained by altering different parameters and factors in this particular learning task. N.B. This will be the last TAMALE seminar this season.
