Abstract

Discusses the features of multimedia products and those features which allow interaction, and considers the key differences between home and work use of information CD-ROMs. Sets out the criteria for the evaluation of products that are likely to contribute to the overall evaluation. These include: the information itself; methods of access; output of information; the quality and appropriateness of the media objects presented; interactive features; aesthetics and creativity; and performance, reliability and robustness

Abstract

Colours, icons, graphics, hypertext links and other multimedia elements are variables that affect information search strategies and information seeking behaviour. These variables are culturally constructed and represented and are subject to individual and community interpretation. Hypothesizes that users in different communities (in intercultural or multicultural context) will interpret differently the meanings of the multimedia objects on the Internet. Users' interpretations of multimedia objects may differ from the intentions of the designers. A study in this area is being undertaken

Abstract

Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

Abstract

Recent technological developments have increased the use of machine learning to solve many problems, including many in information retrieval. Multimedia information retrieval as a problem represents a significant challenge to machine learning as a technological solution, but some problems can still be addressed by using appropriate AI techniques. We review the technological developments and provide a perspective on the use of machine learning in conjunction with knowledge organization to address multimedia IR needs. The semantic gap in multimedia IR remains a significant problem in the field, and solutions to them are many years off. However, new technological developments allow the use of knowledge organization and machine learning in multimedia search systems and services. Specifically, we argue that, the improvement of detection of some classes of lowlevel features in images music and video can be used in conjunction with knowledge organization to tag or label multimedia content for better retrieval performance. We provide an overview of the use of knowledge organization schemes in machine learning and make recommendations to information professionals on the use of this technology with knowledge organization techniques to solve multimedia IR problems. We introduce a five-step process model that extracts features from multimedia objects (Step 1) from both knowledge organization (Step 1a) and machine learning (Step 1b), merging them together (Step 2) to create an index of those multimedia objects (Step 3). We also overview further steps in creating an application to utilize the multimedia objects (Step 4) and maintaining and updating the database of features on those objects (Step 5).

Abstract

The MPEG-7 standard supports the description of both the structure and the semantics of multimedia; however, the generation and consumption of MPEG-7 structural and semantic descriptions are outside the scope of the standard. This article presents two research prototype systems that demonstrate the generation and consumption of MPEG-7 structural and semantic descriptions in retrieval applications. The active system for MPEG-4 video object simulation (AMOS) is a video object segmentation and retrieval system that segments, tracks, and models objects in videos (e.g., person, car) as a set of regions with corresponding visual features and spatiotemporal relations. The region-based model provides an effective base for similarity retrieval of video objects. The second system, the Intelligent Multimedia Knowledge Application (IMKA), uses the novel MediaNet framework for representing semantic and perceptual information about the world using multimedia. MediaNet knowledge bases can be constructed automatically from annotated collections of multimedia data and used to enhance the retrieval of multimedia.

Abstract

Reviews the future possibilities of convergence of digital image storage and dissemination techniques, cable and high resolution television and networks such as the Internet, in bringing sophisticated multimedia information services into the home and businesses. Predicts the future of these systems in publishing, entertainment, education, health care, telephone systems, computer software use, and business and suggests that the ultimate converged system could provide homes and businesses with the means of sending and receiving information by facsimile transmission, making copies, and accessing information from CD-ROM and CD-I drives
