Interpretation, Bug Detection and Bug Diagnosis in Normal Logic Programs

Euschistus servus (Say), Nezara viridula (L.), and Chinavia hilaris (Say) (Hemiptera: Pentatomidae) are economic pests of cotton in the coastal plain of the southeastern United States. The objective of this 2-yr study was to determine the ability of trap cropping systems, pheromone-baited stink bug traps, and a synthetic physical barrier at the peanut-to-cotton interface to manage stink bugs in...

Large open source software projects receive abundant rates of submitted bug reports. Triaging these incoming reports manually is error-prone and time consuming. The goal of bug triaging is to assign potentially experienced developers to new-coming bug reports. To reduce time and cost of bug triaging, we present an automatic approach to predict a developer with relevant experience to solve the n...

If a bug gets fixed in duplicated code, often all duplicates (so called clones) need to be modified accordingly. In practice, however, fixes are often incomplete, causing the bug to remain in one or more of the clones. In this paper, we present an approach to detect such incomplete bug-fixes in cloned code. It analyzes a system’s version history to reveal those commits that fix problems. It the...

Bug triage, deciding what to do with an incoming bug report, is taking up increasing amount of developer resources in large open-source projects. In this paper, we propose to apply machine learning techniques to assist in bug triage by using text categorization to predict the developer that should work on the bug based on the bug’s description. We demonstrate our approach on a collection of 15,...

Changes, a rather inevitable part of software development can cause maintenance implications if they introduce bugs into the system. By isolating and characterizing these bug introducing changes it is possible to uncover potential risky source code entities or issues that produce bugs. In this paper, we mine the bug introducing changes in the Android platform by mapping bug reports to the chang...

The number of bug reports in complex software increases dramatically. Since bugs are still triaged manually, bug triage or assignment is a labor-intensive and time-consuming task. Without knowledge about the structure of the software, testers often specify the component of a new bug incorrectly. Meanwhile, it is difficult for triagers to determine the component of the bug only by its descriptio...

When a new bug report is received, developers usually need to reproduce the bug and perform code reviews to find the cause, a process that can be tedious and time consuming. A tool for ranking all the source files with respect to how likely they are to contain the cause of the bug would enable developers to narrow down their search and improve productivity. This paper introduces an adaptive ran...

Bugzilla is an online software bug reporting system. It is widely used by both open-source software projects and commercial software companies and has become a major source to study software evolution, software project management, and software quality control. In some research studies, the number of bug reports has been used as an indicator of software quality. This paper examines this represen...

The interaction of feeding by a grass bug, Ir"bisia pacifica (Uhler), and drought stress on growth of Great Basin wildrye, Leymus cinereus (Scrih. & Merr.) Love, and intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D. R. Dewey, was studied in the greenhouse. At peak production, control plants of Great Basin wildrye had more than twice as much green leaf area per tiller than bug-i...
