    The emergence of information highways and multimedia computing has resulted in redefining the concept of libraries. It is widely believed that in the next few years, a significant portion of information in libraries will be in the form of multimedia electronic documents. Many approaches are being proposed for storing, retrieving, assimilating, harvesting, and prospecting information from these multimedia documents. Digital libraries are expected to allow users to access information independent of the locations and types of data sources and will provide a unified picture of information. In this paper, we discuss requirements of these emerging information systems and present query methods and data models for these systems. Finally, we briefly present a few examples of approaches that provide a preview of how things will be done in the digital libraries in the near future.published or submitted for publicatio

    The Mirror MMDBMS architecture

    Get PDF
    Handling large collections of digitized multimedia data, usually referred to as multimedia digital libraries, is a major challenge for information technology. The Mirror DBMS is a research database system that is developed to better understand the kind of data management that is required in the context of multimedia digital libraries (see also URL http://www.cs.utwente.nl/~arjen/mmdb.html). Its main features are an integrated approach to both content management and (traditional) structured data management, and the implementation of an extensible object-oriented logical data model on a binary relational physical data model. The focus of this work is aimed at design for scalability

    Resource selection and data fusion for multimedia international digital libraries: an overview of the MIND project

    Get PDF
    The inspiration for MIND grew out of the problems which users face when they have remote access to thousands of heterogeneous and distributed multimedia digital libraries. A user must know where to search, how to query different media, and how to combine information from diverse resources. As digital libraries continue to proliferate, in a variety of media and from a variety of sources, the problems of resource selection, query formulation and data fusion become major obstacles to effective search and retrieval. The key goal of MIND is to develop a common system for identifying, searching and combining results from multiple digital libraries. MIND, therefore, is investigating methods for resource description and selection (i.e., gathering and updating information about digital libraries to assist in selecting those which are most likely to contain the information sought), query processing (i.e. modifying the terms contained in a query and transforming the query into the local command language), data fusion (i.e., the merging of different data retrieved from different digital libraries) and information visualisation (in particular, the automatic generation of surrogates and presentation of fused retrieved data)

    Mobile Exploring of Bulgarian Cultural and Scientific Assets

    The paper introduces an ecosystem of digital libraries and mobile applications for presenting Bulgarian cultural and science assets. The digital libraries concerned constitute valuable sources of cultural heritage and related scientific results. They include the Bulgarian Iconographical Digital Library (BIDL), the BellKnow multimedia archive on bells and the web site of the International Conference on Digital Presentation and Preservation of Cultural and Scientific Heritage (DIPP). These digital libraries can be accessed online through a Web interface. Due to the spread of mobile devices, there is a need to present the contents through mobile platforms as well. The GUIDE@HAND application family was integrated with the digital libraries for presenting the cultural and scientific assets offline in mobile applications. Interactive multimedia components (e. g., games, panorama pictures, maps etc.) make the presentation more attractive. The developed mobile applications facilitate learning, presentation and preservation of cultural and scientific objects

    The design and implementation of an infrastructure for multimedia digital libraries

    Get PDF
    We develop an infrastructure for managing, indexing and serving multimedia content in digital libraries. This infrastructure follows the model of the Web, and thereby is distributed in nature. We discuss the design of the Librarian, the component that manages meta data about the content. The management of meta data has been separated from the media servers that manage the content itself. Also, the extraction of the meta data is largely independent of the Librarian. We introduce our extensible data model and the daemon paradigm that are the core pieces of this architecture. We evaluate our initial implementation using a relational database. We conclude with a discussion of the lessons we learned in building this system, and proposals for improving the flexibility, reliability, and performance of the syste

    Purpose: The purpose of this paper is to know the user perspective regarding various methods of dissemination, to ascertain frequency and purpose of use of different multimedia resources and to analyze the barriers in providing access to them in selected libraries of Delhi viz. Sangeet Natak Akademi (SNA), National School of Drama (NSD) and Eternal Gandhi Multimedia Museum (EGMM). Methodology/Design/Approach: An effort has been taken to record the feedback of the users by way of questionnaires duly filled up by them in order to analyze the use/retrieval of different multimedia resources available in the libraries under study. Hence this paper is based on survey method which is done by the authors with the help of questionnaires and their own observation. Findings: The study explores the utilization of multimedia resources, in digital format, made available online by the libraries under study. Further, it identifies the issues in the usage of multimedia resources in the libraries. Use of other multimedia resources on internet by the users of the libraries has been also recognized. Findings of the study show that TIFF, MP3 and MPEG are the most retrieved file format of multimedia resources. Originality/Value: This type of research oriented studies for understanding the user’s point of view on available library resources and services has not been performed till now in the libraries selected by the authors. In this paper, original and detailed study of multimedia resources as observed by the authors is presented
