- 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
- An electronic classroom with computer workstations and multimedia offers tremendous potential for interactive instruction. To support such instruction, HyperCourseware was developed as an environment and authoring system that recreates on a computer network familiar objects of instruction, such as the syllabus, lecture notes, class rolls, seating chats, exams, and grade lists. In addition, it provides interactive and collaborative tools for group discussion, anonymous feedback, student polling, and shared collaborative wirkspaces. Applications in statistics and cognitve psychology are discussed along with the specific advantages due to hypermedia links, structure of course materials, integration of parts, and classroom interactivity. Student and faculty evaluation have supported the positive educational benefits of both the electronic classroom and HyperCourseware in general

- Abstract
- Develops an integrated conceptual representation scheme for multimedia documents that are viewed to comprise an object-oriented database. Develops the necessary abstractions for the conceptual model and extensions to the RM/T relational model used as the search structure. Develops a retrieval model in which the database search space is 1st narrowed down, based on user query, by an associative search. The associative search is followed by semantic and media-specific searches. A query langugae called SQLX is introduced to fomulate these searches directly from the conceptual model. In SQLX, connector attributes replace join, and abstract data type enables use of objects and their methods in query formulation. Describes a temporal model for time-dependent presentations and with the directions for future work

- Abstract
- A database management system is a general-purpose software system that facilitates the processes of defining, constructing, and manipulating databases for various applications. This article investigates the role of data management in multimedia digital libraries, and its implications for the design of database management systems. The notions of content abstraction and content independence are introduced, which clearly expose the unique challenges (for database architecture) of applications involving multimedia search. A blueprint of a new class of database technology is proposed, which supports the basic functionality for the management of both content and structure of multimedia objects

- Abstract
- Film, videotape and multimedia archive systems must address the issues of editing, authoring and searching at the media (i.e. tape) or sub media (i.e. scene) level in addition to the traditional inventory management capabilities associated with the physical media. This paper describes a prototype of a database design for the storage, search and retrieval of multimedia and its related information. It also provides a process by which legacy data can be imported to this schema. The Continuous Media Index, or Comix system is the name of the prototype. An implementation of such a digital library solution incorporates multimedia objects, hierarchical relationships and timecode in addition to traditional attribute data. Present video and multimedia archive systems are easily migrated to this architecture. Comix was implemented for a videotape archiving system. It was written for, and implemented using IBM Digital Library version 1.0. A derivative of Comix is currently in development for customer specific applications. Principles of the Comix design as well as the importation methods are not specific to the underlying systems used.
