Fuzzy Clustering of Open-Source Software Quality Data: A Case Study of Mozilla

The Role of Local Open Source Communities in the Development of Open Source Projects

“…OSPs begins with a developer/organizer setting the vision or the goal of the project and creating the architecture design for the project and preparing the project before opening up to the public [2,14,17]. Also, on the contribution of the members, it was suggested in the literature that members of open source communities contribute to OSP by efforts which included adding new features, improving old ones, updating, maintenance work and advertising OSP [7].…”

“…Examples of famous OSPs include Mozilla Firefox and Linux Ubuntu [7,14]. Even though open source organizations depend on ultra-distribution, it was observed that many organizations depend on the efforts of local communities that meet face to face to work on OSPs.…”

A method of relational fuzzy clustering based on producing feature vectors using FastMap

“…Another paper that studies fuzzy clustering without prototypes is by Borgelt (Dick and Sadia [21]). An iterative update rule is derived from an objective function that only involves the proximities between data points and the membership degrees of the data points in the various clusters.…”
