Download or read book Combining Information Retrieval Modules and Structural Information for Source Code Bug Localization and Feature Location written by Peng Shao and published by . This book was released on 2011 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bug localization and feature location in source code are software evolution tasks in which developers use information about a bug or feature present in a software system to locate the source code elements, such as classes or methods. These classes or methods must be modified either to correct the bug or implement a feature. Automating bug localization and feature location are necessary due to the size and complexity of modern software systems. Recently, researchers have developed static bug localization and feature location techniques using information retrieval techniques, such as latent semantic indexing (LSI), to model lexical information, such as identifiers and comments, from source code. This research presents a new technique, LSICG, which combines LSI modeling lexical information and call graphs to modeling structural information. The output is a list of methods ranked in descending order by likelihood of requiring modification to correct the bug or implement the feature under consideration. Three case studies including comparison of LSI and LSICG at method level and class level of granularity on 25 features in JavaHMO, 35 bugs in Rhino, 3 features and 6 bugs in jEdit demonstrate that The LSICG technique provides improved performance compared to LSI alone.

Download or read book Effective Bug Detection and Localization Using Information Retrieval written by Ripon Kumar Saha and published by . This book was released on 2016 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software bugs pose a fundamental threat to the reliability of software systems, even in systems designed with the best software engineering (SE) teams using the best SE practices. Detecting bugs early and fixing them quickly are extremely important. However, they are very expensive and challenging, especially at-scale. While the sciences of bug detection (e.g., software testing) and localization via static and dynamic program analyses have been explored considerably, text-based Information Retrieval (IR) techniques for bug detection and localization are interesting and promising new approaches for these problems. One advantage of text-based approaches is that it can utilize a lot of (implicit) semantic information about a program’s functionality from the program text, which is almost impossible to extract using program analysis based techniques. This dissertation builds a deeper understanding of current bug triaging and fixing processes via mining software repositories, and introduces new techniques for effective bug detection and localization. The dissertation has three main parts. First, we perform a number of empirical studies to investigate the extent of and reasons for long lived bugs, their severities, and time spent in different phases of bug fixing process. We demonstrate that many bugs remain unfixed for inordinate period of time due to numerous reasons, including difficulties in detecting, localizing, and fixing them. Second, we demonstrate that developers use very similar program text in source code and their corresponding test cases, which could be utilized to implement powerful test prioritization techniques. We introduce a novel IR based regression test prioritization technique called REPiR that embodies our insight, and show that REPiR is more efficient than program analysis based or dynamic coverage based techniques. Third, we demonstrate that fine grained program text such as class names, method names, variable names, and comments carry different levels of information, and it can be utilized to improve IR based bug localization. We introduce a structured retrieval technique called BLUiR that embodies our insights and show that BLUiR outperforms the existing state-of-the-art IR-based bug localization approaches. Finally, we further improve BLUiR by natural language processing. We make four contributions in this dissertation. One, we provide empirical evidence that there are considerable numbers of non-trivial bugs in software projects that survive for a long time. We describe the reasons for delay in fixing, the nature of fixes, and overall fixing process of these long lived bugs in a great detail. Two, we introduce the notion of IR-based regression test prioritization based on program changes. Three, we introduce the notion of structured retrieval for bug localization. Four, we provide an in-depth analysis of the extent to which natural languages processing can play an important role in improving IR-based bug localization further. The central ideas are embodied in a suite of prototype tools. Rigorous empirical evaluation is performed to validate the efficacy of the proposed techniques using datasets containing a variety of real-world Java and C programs.

Download or read book Knowledge Technology and Systems written by Yoshiteru Nakamori and published by Springer Nature. This book was released on 2023-07-15 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses technology and systems to create valuable ideas from data through the construction of knowledge. The primary concern is to make better decisions about economic and management issues in today’s information-flooded society. Human creative activity is in the realm of soft technology, with no physical entity to operate. Focusing on the ability of knowledge as judgment power, this definition results: “Knowledge technology is soft technology that underpins the human creative activities of converting data and information into knowledge, creating new ideas based on that knowledge and validating those ideas.” That definition includes a wide range of soft technologies developed in informatics, management studies, and systems science. The knowledge system creates ideas from data and knowledge through knowledge technologies. Based on the proposition that knowledge emerges by the interaction between explicit and tacit knowledge, another definition is possible: “The knowledge system is a system that promotes interaction between codified and personalized knowledge and creates ideas for solving a specific problem.” Codified knowledge includes data and information, while personalized knowledge is empirical knowledge or wisdom that is difficult to put into words. Building a knowledge system requires mathematical or intelligent knowledge technology and participatory knowledge technology to create or manage codified knowledge and personalized knowledge. For example, a company builds cross-sectional knowledge systems by gathering human resources from various departments, according to the purpose, as in new product development or sales promotion. Chapter 1 defines knowledge technology and the knowledge system and organizes the challenges in their development, while Chapters 2 through 9 introduce mathematical or intelligent knowledge technologies by researchers at the forefront of knowledge technology development.
