Importing/exporting a bibliography in VisualBib

VisualBib is a Web platform conceived for supporting researchers who wish to create, modify, visualize and share bibliographies; it is freely available for research and teaching, not for commercial purposes, at http://visualbib.uniud.it. Since VisualBib queries the Scopus APIs and Scopus is a commercial service, the user MUST navigate from a subscriber's domain; this restriction does not apply to the other used indexes, OpenCitations and CrossRef/Orcid, being open access. The document (biblio-example-in.bib) in BibTeX format contains minimal metadata; it can be imported by the VisualBib using the button "Import BibTeX", which visualizes the bibliography in a narrative view. Then, applying the seek metadata and the match author wizards is it possible to enrich the bibliography with metadata. Finally, the bibliography can be saved and shared on the cloud in visual format, or in BibTeX format. Here we uploaded the bibliography, enriched by metadata, in BibTeX format (biblio-example-out.bib). Furthemore, this is the link http://bit.ly/2SdPGag for opening the same bibliography in a narrative view of VisualBib

Organizing and evaluating resources and tools for active learning approaches

Innovative teaching and learning practices towards active approaches, require digital tools for creating digital artifacts (such as infographics, mental maps, timelines), for improving the interaction between teachers/students and organizing work groups, for aggregating documents and sources. Although the Web proposes a large offer of applications useful for these aims, there is a lack of knowledge about their existence, their functions and their potential in educational settings. In this paper, we present AppInventory, a visual catalog of 271 applications, organized in a purpose-based taxonomy; starting from a general view that groups the applications in three main macro-categories, users can apply different zooming levels for visualizing the details of the macro-categories, then of the categories, applications, and finally the detailed cards of applications . Users can explore the catalog following personal contextual paths, supported by zz-structures, assigning ratings for each visited application and leaving comments and suggestions

Authoring and Reviewing Bibliographies: Design and Development of a Visual Analytics Online Platform

Researchers are daily engaged in bibliographic tasks concerning literature search and review, both in the role of authors of scientific papers and when they are reviewers or evaluators. Current indexing platforms offer powerful tools for searching bibliographic references, but in general they poorly support the integration, visualization and comparative analysis of metadata coming from subsequent searches. To address these issues, we designed and realized VisualBib(va), an online analytics solution, where a visual environment includes analysis control, bibliography exploration, automatic metadata extraction and metrics visualization for real-time scenarios. Starting from an analysis of tasks, associating them to different user roles, this study enabled us to define a taxonomy of tasks, strictly linked to a set of system requirements for our platform. We introduce and discuss here some relevant functions through two usage scenarios related to the creation and the review of a bibliography. The maturity of the system implementation has allowed us to propose a set of evaluation activities, both carried out by two groups of users with different levels of experience in managing bibliographies, and to collect detailed results based on specific tasks and on general aspects of our framework. VisualBib(va) proved an effective and efficient system for the authoring and reviewing processes of a bibliography

SSD Disparity Estimation for Dynamic Stereo

We analyse experimentally some subpixel-accuracy disparity and uncertainty estimators based on the SSD method, frequently used in stereo and motion analysis. We identify key inadequacies, and introduce new, practical algorithms. We discuss results and performance tests, and demonstrate the effective use of the new estimators in a complete, working system reconstructing dense depth maps using dynamic stereo. The system achieves good accuracy (average percentage errors smaller than few percents) and reliable uncertainty discrimination without any expensive smoothing or regularisation of disparity maps, adopted commonly. 1 Introduction This paper analyses the estimation of subpixel-accuracy disparity and its uncertainty in the context of dynamic stereo for computing dense depth maps [3, 4, 7, 9, 10]. Careful solutions to this problem, supported by adequate solutions to resampling and drop ins/outs, allow us to achieve good reconstructions without expensive smoothing or regulari..
