The book "Mining Software Engineering Data for Software Reuse" offers a comprehensive analysis of software reuse and its application in various phases of the software development process. It addresses different types of data and levels of granularity, examining challenging hypotheses using novel data-driven methods. The goal is to solve problems in requirements gathering, specification extraction, software design, implementation, and quality assurance. The work is complemented by a variety of tools, libraries, and functioning prototypes that illustrate how the phases of the software engineering lifecycle can benefit from the use of data. It is aimed at software engineering researchers, experts, and practitioners who can utilize the presented methods to extract knowledge from software data and make effective decisions. Master's level students in software engineering will also find valuable information in this book.
