| Abstract | Much recent research effort has been devoted to designing efficient code clone detection techniques and tools. However, there has been little human-based empirical study of developers as they use the outputs of those tools while performing maintenance tasks. This paper describes a study that investigates the usefulness of code clone information for performing a bug localization task. In this study 43 graduate students were observed while identifying defects in both cloned and non-cloned portions of code. The goal of the study was to understand how those developers used clone information to perform this task. The results of this study showed that participants who first identified a defect then used it to look for clones of the defect were more effective than participants who used the clone information before finding any defects. The results also show a relationship between the perceived efficacy of the clone information and effectiveness in finding defects. Finally, the results show that participants who had industrial experience were more effective in identifying defects than those without industrial experience. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
