- 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
- Ein Problem der Erstellung von Multimediaanwendungen in Unternehmen ist, dass die Sachkompetenz bezüglich der darzustellenden Inhalte nicht immer bei denjenigen Mitarbeitern liegt, die die Kompetenz für die mediengerechte Aufbereitung haben. Um umfangreiche Hypertextanwendungen - ggf. auch mit interaktiven Aufgaben Lind Multimediaelernenten - zu erzeugen, können Sachautoren von dem Umgang mit Multimediasoftware weitgehend entlastet werden. Der von den Sachautoren verfasste Text ist dazu von vornherein mit minimalen Textauszeichnungen zu versehen. Dazu braucht er seine Textverarbeitung nicht zu verlassen. Um jetzt einen interaktiven Hypertext oder eine 1 lypermediaanwendung mit einzelnen Einträgen und zusätzlichen umfangreichen Navigationskomponenten zu erzeugen und weitere Medien an den jeweils richtigen Stellen einzufügen, ist ein Programm erforderlich, das die Anwendung erzeugen hilft (Engine). Zu den Themen "Hypertext" und "Multimedia" erscheinen etliche Publikationen. Eine Vielzahl von ihnen hat theoretische und konzeptionelle Aspekte zum Inhalt (z. B. Lobin 1999, Brusilovsky 1998, Rouet 1996). Manche betonen den Anwendungsbezug (Gerdes 1997, Hofinann/Simon 1995), der unter besonderer Berücksichtigung für Information oder Ausbildung gesehen werden kann (vgl. Glowalla 1992). Andere sind von historischem Interesse (Nelson 1992), klären die Begrifflichkeit und die Grundlagen (Schnupp 1992, Kuhlen 1991, Seyer 1991, Nielsen 1990, Hashim 1990) oder geben Hinweise auf die Benutzung (MacGrew 1989). Ferner gibt es programmspezifische Literatur, die die technische Handhabung bei der Erstellung unterstützt. Solche Literatur kann genutzt werden, um Aspekte zu gewinnen, die für die Anlage und Ausrichtung einer Hypertextanwendung sinnvoll sind. Werden hingegen existierende Hypertextanwendungen betrachtet, so bleibt der damit verbundene Aufwand und die Organisationsstruktur oft im Dunkeln

- Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.

- 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
- This article provides an overview of our experiments in using MPEG-7 in a television news retrieval application. Our study is based on a survey of professional users in the Television Suisse Romande (TSR) television news production environment. We present here two main issues. First, we describe the way the generic and voluminous MPEG-7 Schema can be exploited in the context of a specific application domain. Second, we discuss the problem of how to search MPEG-7 descriptions, which are detailed and complex by nature, via a high-level user-oriented retrieval model.

- Abstract
- Various kinds of knowledge organisation, such as thesauri, are routinely used to label or tag multimedia content such as images and music and to support information retrieval, i.e. user search for such content. In this paper, we outline why this is the case, in particular focusing on the semantic gap between content and concept based multimedia retrieval. We survey some indexing vocabularies used for multimedia retrieval, and argue that techniques such as thesauri will be needed for the foreseeable future in order to support users in their need for multimedia content. In particular, we argue that artificial intelligence techniques are not mature enough to solve the problem of indexing multimedia conceptually and will not be able to replace human indexers for the foreseeable future.
