Learning through multimedia

Abstract: The creation of multimedia composition tools for young learners is addressed. The factors to consider in designing composing tools are discussed. Such a set of tools, called the Multimedia Works software environment, is described. It consists of three programs: Media Space, a multimedia database and research program; Multimedia Works Composer, a storyboarding and presentation program; and Video Light Table, a direct manipulation video-clip editor. The use of student participation in developing the tools is also described. Some problems that are being worked on are examined. >

An architecture for a multimedia database management system supporting content search

Abstract: Advanced applications frequently require the management of multimedia data like text, images, graphics, sound, etc. While it is practical for today's computers to store these types of data, managing them requires the search of them based on their contents. Database management systems should be extended to organize these new types of data and to enable content search. However, the complexity of the contents and their semantics makes content search of these data a very difficult problem. This paper proposes to have multimedia data accompanied by natural language descriptions that will be used for content search of these data. A parser is used to interpret the descriptions and to later match them semantically with queries. Implications and difficulties of such an approach are discussed.

Cognitive view mechanism for multimedia database system

Abstract: Describes a cognitive human interface for visual interaction with image database systems. The authors' approach gives a general framework of visual interaction. They adopt both an image model and a user model to interpret and operate the contents of image data from the user's viewpoint. The image model describes the physical constraints of image data, while the user model reflects the visual perception processes of the user. They propose the algorithms for typical visual interaction styles; a query by visual example (QVE) and a query by subjective descriptions (QBD). The former includes a sketch retrieval function, and a similarity retrieval function and the latter includes a sense retrieval function. These algorithms are developed for their experimental database system, the TRADEMARK and the ART MUSEUM. These functions use a pictorial index created by image analysis and a personal index automatically learned as the user model. >

A Friendly and Intelligent Approach to Data Retrieval in a Multimedia DBMS

Abstract: Manipulation of multimedia data is not straightforward as in conventional databases. One main problem is the retrieval of multimedia data from the database with the need to match the contents of multimedia data to a user query. In order to achieve a content based retrieval, in our approach, we use natural language captions which allow the user to describe the contents of multimedia data In a similar manner, users will specify their queries on multimedia data contents in natural language form. A problem is that different or even the same user describe the same thing differently at different times which results in the descriptions of the contents of multimedia data to rarely exactly match the descriptions of the user queries. Hence, partial or approximate match between descriptions of multimedia data and user queries is generally required during multimedia data retrieval. We propose an intelligent approach to approximate match by integrating both object-oriented and natural language understanding techniques. In order to make the query specification process easier we also develop a graphical user interface supporting incremental query specification and a natural way of expressing joins. The Multimedia Database Management System (MDBMS) described in this paper incorporates the capabilities as mentioned above.

A Graphical Database Interface for a Multimedia DBMS

Abstract: : In this paper we describe the GRAphical Database Interface (GRADI) of a Multimedia Database Management System. As generally true, the user interface is an important part of a system which strongly determines the effectiveness of using it. In order to find a natural way of interacting with the MDBMS system we examined the query specification process used by humans. We found that incremental query specification, natural ways of expressing joins and an additional 'all'-operator are important to improve the query specification process making it considerably easier to use in comparison with query languages like SQL. The Graphical Database Interface described in this paper incorporates the mentioned capabilities as part of the MDBMS system. We think that the principles are of general use not only for multimedia systems but for any database query interface.

Exploiting Captions for Access to Multimedia Databases

Abstract: : Descriptive captions help organize noncompetitive media. But automated use of captions in retrieval from computerized multimedia databases has not been much examined because it would seem to require significant natural language processing. We argue that captions can be naturally expressed in a restricted language whose interpretations is easier than general natural- language understanding. We describe a multimedia database system that stores interpreted captions in predicate calculus for each media datum; it then interprets restricted-language queries, and finds matching media objects.

Multilingual aspects of a multimedia database of learning materials

Abstract: This article presents a summary of approaches to the development of multilingual software and relevant multicultural issues. It gives a definition of multilinguality and moves on to present a framework for a multilingual database of learning materials. In this context, a general specification of multilingual aspects of a browser system are presented. In addition, the article considers the multicultural aspects of a database of learning materials. A number of problems are identified which need to be dealt with in this context.

HOLOTHEQUE: A Multimedia Database System for Ethnology Studies.

Abstract: The National Museum of Ethnology was established in 1974 as an Inter-Universfty Research institute. The principal functions of the Museum are: (1) to conduct research and investigatlon In ethnology; (2) to collect, maintain, and exhibit ethnological rnaterials; and (3) through these activities, to deepen the general public's understanding and awareness of the various societies, cultures, and peoples of the world.

Map Summarization using Analogical Matching of Schema

Abstract: Recently in public enterprise companies, the demand for utilizing the multimedia database (MMDB) is rising. Such MMDB is used in the strategy information system (SIS) not only for special purposes such as facility management but also for the more general office sections. But there exists structural mismatch between user specified schema and a priori memolized schema of MMDB. Therefore, we express multimedia as object oriented structures and investigate analogical matching method of extracting the part of the structure that resembles the user specified scheme structure from this multimedia database. This new method is applied to an example that automatically summalize map for guidance from the residential map. As a result, we can get a prospect that an effective automatic summarization of map.

Three dimensional data architecture in a multimedia database on cardiac arrhythmia

Abstract: The authors discuss three-dimensional text, the architecture developed to organize a large amount of information in a hypertext system so that it is easily accessible by a diverse group. Information is divided into topics, sections, and level of detail; this organization can be represented as a three-dimensional knowledge space. This methodology has been applied to the Entropy Multimedia Database on cardiac arrhythmias. Three-dimensional text can be applied to many large information systems, resulting in improved organization and ease of navigation. >
