Background and Objective

Bugzilla is a bug tracking system from Mozilla. It is used to develop and maintain hundreds of software products, consisting of thousands of components. As new bugs are submitted into the system, their triaging (categorization by products and software components) becomes time and resource consuming, as many bug reporters are not closely familiar with internal division of software they use into products and component. Thus, members of the Mozilla development team are assigned to be gatekeepers, who categorize and prioritize incoming bugs. This manual bug triaging consumes the time of experienced engineers, which may be spent better, otherwise.

In this Marathon Match, we will give you real data from the bug tracking system and ask to implement an algorithm for automatic bug triaging. Given the details of a submitted bug, your algorithm will deduce the software component that bug belongs to, and the confidence score of this deduction.

Mozilla LP - Scoring


In a few words: to score your predictions, we’ll sort them by decrease of the confidence score; then we go along the predictions, from the highest to the lowest confidence score, and we sum-up scoring_weights of the bug categories for all correctly categorized bugs, reducing each element of the sum proportionally to the sum of scoring_weights for incorrectly categorized bugs seen so far. Finally, we normalize the result so that 1 000 000 is the maximum possible score, and 750 000 is the threshold to be eligible for a prize.
