4 Analysis of Version Selecting on Open Source Software Library Keisuke Fujino Abstract The principle aim of this paper was to provide a reliable guideline for software developers who want to use the open source software library. They should not always use the latest versions. For example, quality is important in the large scale systems. In the previous study, most popular version is recommended based on the wisdom of the crowds. However, there is the example that many users downgrade after reporting bugs in the library which they are using. Therefore, the wisdom of crowds is not always reliable when they select library. In this paper, to provide a reliable guideline, I investigate the version selection through the case study of 4 Java logging libraries (Log4j, Slf4j, Commons logging, and Logback) from the initial release to plateau. From the results, users select different version in the soon after initial release, but many users will come to use same version after a certain time. Therefore, after version selection of users converged, the wisdom of crowds is available to select version. In addition, I clear the extreme trend version increases as soon as the bug fixing curve begins to converge. Keywords: Open Source Software, Software Library, Bug Fixing Curve, Software Reliability Growth Model, The Wisdom of Crowds Master s Thesis, Graduate School of Information Science, Nara Institute of Science and Technology, NAIST-IS-MT , March 13, ii
