Abstract

Models administrative and operating costs surrounding a hypermedia database and determines 7 conditions for the cost justification of hypermedia; higher linking costs proportionately reduce the total number of links implemented; increasing the benefits from using the database increases the total number of links proportionately; increasing database size results in an increase in the total number of links implemented; if the database user learns from the database slowly, then a larger number of links need to be provided: the maximum size of databases which is justified on cost will increase as the average cost of linking each node becomes smaller; the total benefit from usage required in order to cost justify a database will decrease as the average cost of linking each node becomes smaller and the maximum size of database which is cost justified will increase rapidly as the learning rate increases. The learning rate can be increased by construction of links and nodes so that they are maximally informative

Abstract

Hypermedia and multimedia have been placed rather uncritically at the centre of current developments in learning technology. This paper seeks to ask some fundamental questions about how learning is best supported by hypermedia, and concludes that the most successful aspects are not those normally emphasized. A striking observation is that the best learning experience is enjoyed by hypermedia courseware authors rather that students. This is understandable from a constructivist view of learning, in which the key aim is to engage the learner in carrying out a task which leads to better comprehension. Deep learning is a by-product of comprehension. The paper discusses some approaches to designing software - cognitive tools for learning - which illustrate the constructivist approach

Abstract

In this article, we introduce a user preference model contained in the User Interaction Tools Clause of the MPEG-7 Multimedia Description Schemes, which is described by a UserPreferences description scheme (DS) and a UsageHistory description scheme (DS). Then we propose a user preference learning algorithm by using a Bayesian network to which weighted usage history data on multimedia consumption is taken as input. Our user preference learning algorithm adopts a dynamic learning method for learning real-time changes in a user's preferences from content consumption history data by weighting these choices in time. Finally, we address a user preference-based television program recommendation system on the basis of the user preference learning algorithm and show experimental results for a large set of realistic usage-history data of watched television programs. The experimental results suggest that our automatic user reference learning method is well suited for a personalized electronic program guide (EPG) application.

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

Reviews studies showing that multimedia may be able to help people learn more information more quickly compared to traditional classroom lectures. Redundant multimedia does not always improve learning compared to monomedia. Specific situations in which multimedia information may help people to learn include: when the media encourage dual coding of information, when the media support one another, and when the media are presented to learners with low prior knowledge or aptitude in the domain being learned. Specific multimedia can be used to help people learn specific kinds of information

Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.

Abstract

Describes a hypermedia application that provides students reading German texts with advance organizers in the form of a movie clip designed to facilitate global comprehension and glosses for words in the form of text, graphics, video, and sound. Results of testing indicate that studuents not only reported the photograph and movie links as most helpful for learning vocabulary, but in fact chose them more than text. Performance on vocabulary tests showed that when links were accessed, words were recalled correctly approximately 75% of the time. Learner behaviour data showed that so called visualizers and verbalizers performed equally well on the vocabulary tests but accessed different modes of information (links) corresponding to their respective cognitive styles

Abstract

Multimedia information systems, supplied on CD-ROM, are fast becoming a popular consumer product. A huge and growing range of titles is available from high street computer, electronic goods and book shops. Provides a compact set of evaluation criteria for these products, using established methods in the fields of human-computer interaction (HCI), computer-assisted learning (CAL), and information retrieval. The needs and desires of the home user are substantially different from those of the workplace or education user. Observation from product use, and an interview study with home multimedia users, suggests that factors such as aesthetics, levels of interactivity and information content may be crucially important in user satisfaction. Factors such as interface clarity and consistency may be less important than in workplace systems

Abstract

Purpose - The aim of this paper is to ask why the libraries and the computer and media centres of German universities are picking up too little to improve the conditions for learning, teaching and research. Design/methodology/approach - With the founding of the Information, Communication and Media Center/Informations-, Kommunikations- und Medienzentrums (ICMC/IKMZ), the central services of the Brandenburg Technical University of Cottbus (BTU Cottbus) library, computer center, multimedia center and administrative data processing were combined on a common management level, and the prerequisites for the development of integrated information management were created. Findings - On this basis the following goal was set: the realization of more efficient organizational structures for a broad spectrum of customer- and service-oriented information, communications and media (ICM) offers for research, teaching and administration. Originality/value - The paper gives an overview of German discussion on the convergence of services, and presents the ICMC/IKMZ of Cottbus University as an example of a converged institution.

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.
