Isolating code related to a certain functionality in a reuse re-engineering process

Software re-engineering and reusability are two areas of growing interest in the last years. However, while many researchers have focused their interest in the classification of reusable modules proposing meaningful examples of reusable components repositories and software packages libraries, the problem of potential reusable chunks searching and extracting is still opened. In this paper, after a brief discussion of the re-engineering issues, we examine the problems related to the difficulty of identifying various subfunctionality in a module and isolating them.
