Bug Triaging is a vital part of issue management systems. Bug triaging deals with assigning a developer the task of an incoming bug. This activity is error prone and time consuming if done manually. There is a need for automated support to accelerate this process. The current automated bug triaging systems exploits the text contents of the bug and the tossing relations among the developers. The...

Although bug tracking systems are fundamental to support virtually any software development process, they are currently suboptimal to support the needs and complexities of large communities. This dissertation first presents a study showing empirical evidence that the traditional interface used by current bug tracking systems invites much noise— unreliable, unuseful, and disorganized information...

Bug Triaging is an important aspect of Bug Management in Open Source Systems. Bug Triaging pertains to assignment of a newly opened bug to an appropriate developer for resolution. This task is complicated in an open source environment because of the nature of the Open Source Development. Open Source Software Development comprises of the developers who are volunteers. The volunteers are distribu...

In the bug triage we have an unavoidable step of fixing the bugs which helps in correctly assigning a developer to a new bug. Text classification and binary classification techniques are applied to decrease the time cost in manual work and to enhance the working of automatic bug triage. We address the problem of data reduction and hence we combine the instance selection and the feature selectio...

A typical bug fixing cycle involves the reporting of a bug, the triaging of the report, the production and verification of a fix, and the closing of the bug. However, previous work has studied two phenomena where more than one fix are associated with the same bug report. The first one is the case where developers re-open a previously fixed bug in the bug repository (sometimes even multiple time...

The bed bug resurgence in North America, Europe, and Australia has elicited interest in investigating the causes of the widespread and increasing infestations and in developing more effective control strategies. In order to extend global perspectives on bed bug management, we reviewed bed bug literature in China by searching five Chinese language electronic databases. We conducted telephone int...

This work presents threshold tracing schemes. Tracing schemes trace the source of keys which are used in pirate decoders for sensitive or proprietary data (such as pay-TV programs). Previous tracing schemes were designed to operate against any decoder which decrypts with a nonnegligible success probability. We introduce threshold tracing schemes which are only designed to trace the source of ke...

Many illegal copies of digital movies by camcorder capture are found on the Internet or on the black market before their official release. Due to the angle of the camcorder relative to the screen, the copied movies are captured with perspective distortion. In this paper, we present a watermarking scheme for tracking the pirate using local auto-correlation function (LACF) to estimate geometric d...

With the increasing number of bug reports coming into the open bug repository, it is impossible to triage bug reports manually by software managers. This paper proposes a novel approach called En-LDA (Entropy optimized Latent Dirichlet Allocation (LDA)) for automatic bug report assignment. Specifically, we propose entropy to optimize the number of topics of the LDA model and further use the ent...

Software bug classification is a precondition for bug fixation and it plays a vital role in software maintenance. It is found that bug fixation often takes long due to the distribution of misclassified or non-classified bugs by the triager among the developers. In this paper, we propose an adaptive bug classification approach on CVE dataset that involves two Bayesian classifiers such as Naive B...
