The DChanges series of workshops focuses on changes in all their aspects and applications: algorithms to detect changes, models to describe them and techniques to present them to the final users are only some of the topics we investigate. The workshop is open to researchers and practitioners from industry and academia. In this edition, we will follow up on the discussion of DChanges 2014 about algorithms and interfaces to better understand and exploit detected changes, and about standards for modeling and transmitting changes. Particular attention will also be given to the use of these techniques in digital humanities - for instance in the studies of collation, text genetics and plagiarism detection - and for real-time collaborative editing.

We introduce a new concept in document layout optimization. In our approach, paraphrase-based~layout~optimization, layout issues (e.g. widows due to poor page breaking) are automatically fixed by rewording the neighboring sentences. Techniques of paraphrasing are borrowed from the field of natural language processing towards this goal, which is the first attempt in the field of document engineering. We implemented a prototype TeX pre/post-processing system that includes two simple paraphrase generators. The experiment shows that our approach is promising and effective for improving document layout.

This paper presents and discusses the internal operation of NCLSC (NCL Stereo Converter): a tool to convert a 2D interactive multimedia application annotated with depth information to a stereoscopic-multimedia application. Stereoscopic-multimedia applications are those that codify both the left-eye and right-eye views, as required by stereoscopic 3D displays. NCLSC takes as input an NCL (Nested Context Language) document and outputs an NCL stereoscopic application codified in side-by-side or top-bottom format (both common input formats for 3DTV sets). NCL is the declarative language adopted in most Latin America countries for terrestrial digital TV middleware systems and the ITU-T H.761 Recommendation for IPTV services. However, the proposed approach is not restricted to NCL and can be used by other languages. The depth annotation allows for positioning each 2D graphical component in a layered (2.5D or 2D+depth) user interface. It is used by NCLSC to compute the screen parallax (offset) between the graphical elements in the left and right views of the resulting stereoscopic application. When the resulting application is presented on stereoscopic 3D displays, such screen parallax induces retinal disparity, which creates the illusion of floating flat-2D graphical elements. NCLSC does not require any additional native middleware support to run in currently available 3D-enabled TV sets. Moreover, NCLSC can adapt, at run-time, the output application to different display sizes, viewer distances, and viewer preferences, which are usually required for a proper balance between artistic effects and user experience.

This work is concerned with the digitization and analysis of historical documents. The investigation of the documents has been conducted in three successive interdisciplinary projects. The team involved in the projects consists of philologists, chemists and computer scientists specialized in the field of digital image processing. The manuscripts investigated are partially degraded since they have been infected by mold, are corrupted by background clutter or contain faded-out or even erased writings. Since these degradations impede a transcription by scholars and worsen the performance of automated document image analysis techniques, the documents have been imaged with a portable multispectral imaging system. By using this non-invasive investigation technique, the contrast of the faded out characters can be increased, compared to ordinary white light illumination. Post-processing techniques, such as dimension reduction tools, can be used to gain a further legibility increase. The resulting images are used as a basis for further document analysis methods. These methods have been especially designed for the historical documents investigated and involve Optical Character Recognition and writer identification. This paper presents an overview on selected methods that have been developed in the projects.
