NEW YORK, May 22, 2013 /PRNewswire/ -- Special issue 3D Object Retrieval captures executable codes within online article frameworkensuring easy reproducibilityElsevier, a world-leading provider of scientific, technical and medical information products and services, is pleased to announce that its journal Computers & Graphics for the first time has published executable papers in its special issue on 3D Object Retrieval within the online article framework on ScienceDirect. An executable paper combines the narrative of a traditional scholarly paper with embedded data sets and computer code that underlie the reported results. Readers can inspect code, change parameters, upload their own test data, and re-run code to probe the paper's computational methods and verify the author's results. In 2011 Elsevier launched its Executable Papers Grand Challenge for the computer science community to address the question of how to reproduce computational results within the confines of the research article. First-place winner the Collage Authoring Environment, from a Polish team affiliated with CYFRONET, proposed a web-based tool that allows authors to capture their computational methods and interweave those with the online article. Computers & Graphics has now incorporated this wining methodology within the online article framework of ScienceDirect for the articles published in its most recent special issue on 3D Object Retrieval. Professor Joaquim Jorge of INESC-ID / Instituto Superior Técnico in Portugal and Editor-in-Chief of Computers & Graphics, as well as guest editors Dr. Michela Spagnuolo and Prof. Remco Veltkamp were instrumental in building support for the project from within the graphics community and the resulting pilot has longer term applications across multiple disciplines. "Most experiments in the field of computer science are difficult or impossible to reproduce without full access to data and coding", said Ann Gabriel, Publishing Director of Computer Science Journals at Elsevier. "Executable papers allow authors to create a numerical experiment that belongs with their article. This experiment contains one or more pieces of computer code, together with all the data sets that may be necessary to execute the code. By capturing the full methodology, the Collage system ensures that results are fully reproducible. Elsevier is proud to launch this breakthrough development: a fully integrated, seamless user experience that allows the reader to explore full computational elements and coding while reading the article." Publishing these first executable papers on ScienceDirect forms a part of the Article of the Future, Elsevier's program to continuously improve and innovate the online article format.
