Duplicate finder toolkit

Software documentation is a significant component of modern software systems. Each year it becomes more and more complicated, just as the software itself. One of the aspects that negatively impact documentation quality is the presence of textual duplicates. Textual duplicates encountered in software documentation are inherently imprecise, i.e. in a single document the same information may be presented many times with different levels of detail and in various contexts. Documentation maintenance is an acute problem, and there is a strong demand for automation tools in this domain. In this study we present the Duplicate Finder Toolkit, a tool which assists an expert with duplicate maintenance-related tasks. Our tool can facilitate the maintenance process in a number of ways: 1) detection of both exact and near duplicates 2) duplicate visualization via heat maps 3) duplicate analysis - comparison of several duplicate instances, evaluation of their differences, exploration of duplicate context 4) duplicate manipulation and extraction.
