DocMIR: An automatic document-based indexing system for meeting retrieval

This paper describes the DocMIR system which captures, analyzes and indexes automatically meetings, conferences, lectures, etc. by taking advantage of the documents projected (e.g. slideshows, budget tables, figures, etc.) during the events. For instance, the system can automatically apply the above-mentioned procedures to a lecture and automatically index the event according to the presented slides and their contents. For indexing, the system requires neither specific software installed on the presenter's computer nor any conscious intervention of the speaker throughout the presentation. The only material required by the system is the electronic presentation file of the speaker. Even if not provided, the system would temporally segment the presentation and offer a simple storyboard-like browsing interface. The system runs on several capture boxes connected to cameras and microphones that records events, synchronously. Once the recording is over, indexing is automatically performed by analyzing the content of the captured video containing projected documents and detects the scene changes, identifies the documents, computes their duration and extracts their textual content. Each of the captured images is identified from a repository containing all original electronic documents, captured audio-visual data and metadata created during post-production. The identification is based on documents' signatures, which hierarchically structure features from both layout structure and color distributions of the document images. Video segments are finally enriched with textual content of the identified original documents, which further facilitate the query and retrieval without using OCR. The signature-based indexing method proposed in this article is robust and works with low-resolution images and can be applied to several other applications including real-time document recognition, multimedia IR and augmented reality system

Implementation and Assessment of a Blended Learning Environment in Postgraduate Education

The article is devoted to the description of information technology (IT) tools in teaching foreign languages to PhD students in a digital environment. The authors describe the methodological basis for designing an assessment system that is relevant to the specific character of digital education, clarify the main functions of new assessment tools and determine the peculiarities of this activity in connection with information technology. The article deals with explaining the use of IT tools with an emphasis on the study of the educational content of the student and the development of personal soft skills. The results include monitoring the performance achieved in the learning process, authors’ observations and research based on post graduates’ outcomes and aimed at monitoring the development of their own perspective. The findings were confirmed by prognostic simulation and experimental learning. According to the authors, the use of information technology tools, as well as technology-based assessment, is based on principles which tend to challenge traditional learning and teaching practices and, thus, affect education policies and systems. On the other hand, piloting this technology has outlined a promising range of problems that need to be addressed in further research related to higher education. Keywords: digital environment, technology-based assessment, blended learning, a postgraduate course, soft skills, professional developmen

WLAP the Web Lecture Archive Project: The Development of a Web-Based Archive of Lectures, Tutorials, Meetings and Events at CERN and at the University of Michigan

This paper summarizes the results of a project to develop an electronic repository of "content-rich" lectures, talks, and training activities on the World-Wide Web. The work was carried out from July 1999 to July 2001 by a collaboration consisting of the University of Michigan ATLAS Collaboratory Project, the University of Michigan Media Union, the CERN HR Division, supported by the CERN IT and ETT Divisions and the CERN Academic and Summer Student Programs. In this document, we describe the software application chosen to synchronize the slide presentations to the video recordings, provide technical solutions to the various recording and archival challenges encountered during the project, and propose a set of research and development issues we feel merit further investigation. We also present the concept of a "Lecture Object" and suggest the adoption of standards so that lectures at multiple institutes can be seamlessly shared and incorporated into federated databases world-wide

Trendswatch 2013: Back to the Future

TrendsWatch 2013 highlights six trends that CFM's staff and advisors believe are highly significant to museums and their communities, based on our scanning and analysis over the past year. For each trend, we provide a brief summary, list examples of how the trend is playing out in the world, comment on the trend's significance to society and to museums specifically, and suggest ways that museums might respond. We also provide links to additional readings. TrendsWatch provides valuable background and context for your museum's planning and implementation
