Towards Effective Bug Triage with Software Data Reduction Techniques

International audienceSoftware companies spend over 45 percent of cost in dealing with software bugs. An inevitable step of fixing bugs is bug triage, which aims to correctly assign a developer to a new bug. To decrease the time cost in manual work, text classification techniques are applied to conduct automatic bug triage. In this paper, we address the problem of data reduction for bug triage, i.e., how to reduce the scale and improve the quality of bug data. We combine instance selection with feature selection to simultaneously reduce data scale on the bug dimension and the word dimension. To determine the order of applying instance selection and feature selection, we extract attributes from historical bug data sets and build a predictive model for a new bug data set. We empirically investigate the performance of data reduction on totally 600,000 bug reports of two large open source projects, namely Eclipse and Mozilla. The results show that our data reduction can effectively reduce the data scale and improve the accuracy of bug triage. Our work provides an approach to leveraging techniques on data processing to form reduced and high-quality bug data in software development and maintenance

A Survey on Bug Triage Using Data Reduction Technique

Most of the software companies needs to deal with software bug in every day. Software companies spend most if their cost in dealing with software bugs. The process of fixing bug is bug triage, which aims to assign a expert developer to a new bug. To reduce the time and cost in manual work, we apply text classification technique to conduct automatic bug triage. In proposed system we apply data reduction techniques on bug data set to improve the scale and quality of bug data. We use instance selection and feature selection simultaneously to reduce the scales on bug dimension and word dimension and improve the accuracy of bug triage. In this paper, we investigate the use of five term selection methods on the accuracy of bug assignment. In addition, we re-balance the load between developers based on their experience

Effective Bug Assortment Using Data Reduction Techniques

Software companies spend over 48% of their total cost to fix the bugs. An effective way to automatically fix the bugs to the correct developer is called Bug Triage or Bug Assortment. Data sets containing the bug reports are collected from two large open source projects like Mozilla and Firefox. These projects consist of open source bug repositories. Bug repositories are large repositories which stores all the details of bugs. The details are stored in the form of a bug report. These bug report are saved as a document and a related developer is mapped to the label of the document. Software companies spend most of their total cost in fixing these bugs. In bug repositories the two main challenges faced is the large quantity of the data set and the low quality. Noise and redundancy are the main cause for the low quality of the data set. However, irrespective of all these difficulties assigning a proper developer to fix the bug is not an easy task without knowing the actual class of the bug. In this paper we propose data reduction technique which reduces the high scale of the data but it retains the quality of the data set. We also propose domain wise bug solution

A Survey Paper on Software Bug Classification Techniques using Data Mining

A Software bug is a blunder, blemish, disappointment or deficiency in a PC project or framework that causes it to deliver an off base or surprising result. At the point when bugs emerge, we need to settle them which is difficult. The greater part of the organizations burn through 40% of expense to settling bugs. The procedure of altering bug will be bug triage or bug collection. Triaging this approaching report physically is blunder inclined and tedious .programming organization pays the greater part of their expense in managing these bugs. In this paper we arranging the bugs with the goal that we can decide the class of the bug at which class that bug is has a place and in the wake of applying the order we can dole out the specific bug to the precise designer for altering them. This is effective. In this paper we are utilizing mix of two grouping strategies, guileless bayes (NB) and k closest neighbor (KNN).In advanced days organization utilizes programmed bug triaging framework yet in Traditional manual Triaging framework is utilized which not effective and setting aside an excess of time .For is triaging the bug we require bug subtle element which is called bug store. In this paper we likewise diminishing the bug dataset in light of the fact that on the off chance that we having more information with unused data which causes issue to relegating bugs. For actualizing this we utilize occasion determination and highlight choice for lessening bug information. This paper portray the entire methodology of bug assignment from beginning to end and finally result will appear on the premise of chart .Graph speaks to the most extreme plausibility of class means at which class the bug will has a place

Framework for Automatic Bug Classification in Bug Triage System

A Software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result. When bugs arise, we have to fix them which is not easy. Most of the companies spend 40% of cost to fixing bugs. The process of fixing bug is bug triage or bug assortment. Triagingthis incoming report manually is error prone and time consuming .Software companies spend most of their cost in dealing with these bugs. In this paper we classifying the bugs so that we can determine the class of the bug at which class that bug is belongs and after applying the classification we can assign the particular bug to the exact developer for fixing them. This is efficient. In this paper we are using combination of two classification techniques ,na�ve Bayes (NB) and k nearest neighbor(KNN).In modern days company uses automatic bug triaging system but in Traditional manual Triaging system is used which is not efficient and taking too much time .For triaging the bug we require bug detail which is called bug repository. In this paper we also reducing the bug dataset because if we having more data with unused information which causes problem to assigning bugs. For implementing this we use instance selection and feature selection for reducing bug data. This paper describe the whole procedure of bug allotment from starting to end and at last result will show on the basis of graph .Graph represents the maximum possibility of class means at which class the bug will belongs

Survey on Automated Bugs Triage System

Nowadays IT companies is spending more than 40 percent of their cost in fixing software bugs, traditonally these bugs are fixed by manual assignement to a particular developer , this approach causes too much dependency, the new and alternative approach is the bug triage system which fix the bug automatically , which automatically assign the reported bug to a develop which decreases the time and cost in in manual work, different classification techniques are used to conduct automatic bug triage. In this paper, we propose to apply machine learning techniques to assist in bug triage to predict which developer should be assigned on the bug based on its description by applying text categrorization . We will address the problem of data reduction for bug triage, i.e. How the quality of bug data would be improved
