Content oriented visual interface using video icons for visual database systems

Abstract: This paper clarifies the importance of content oriented visual user interfaces using video icons for visual database systems. Effectiveness of both still and live video images, especially for user's browsing and interaction, is shown by usage of the 'MediaBENCH' (hyperMedia Basic ENvironment for Computer and Human interactions) which is a basic prototype multimedia database system. Various methods of handling video data on the MediaBENCH are introduced and discussed to show how video data can be manipulated on visual database systems which deal with spatial and temporal factors. A visual interface using video icons is quite suitable to video editing systems, video mail systems, or other electronic video document systems. Brief application profiles are shown for guidance.

Trademark: Multimedia image database system with intelligent human interface

Abstract: An experimental multimedia database system TRADEMARK is being developed. This system includes image processing facilities as the primitive data operations. It provides (a) automatic image data registration and automatic indexing by abstracted image representation, (b) similarity retrieval from actual visual examples, and (c) multimedia document formatting of retrieved data. Similarity retrieval in this system also permits handwritten and rough sketches as visual examples. Its ability in similarity operations is also evaluated experimentally. The design principle proposed here is based on a hyperobject-oriented model which has the following features: (i) knowledge base-like representation of object world, (ii) extensive architecture by deduction of logic database, and (iii) AI-oriented human interface.

Intelligent Multimedia Computer Systems: Emerging Information Resources in the Network Environment

Abstract: A multimedia computer system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full‐motion video, and text information. This paper surveys four possible types of multimedia computer systems: hypermedia, multimedia database, multimedia message, and virtual reality systems. The primary focus is on advanced multimedia systems development projects and theoretical efforts that suggest long‐term trends in this increasingly important area.

Design and Implementation of a Multimedia DBMS: Catalog Management, Table Creation and Data Insertion

Abstract: : Current Database Management Systems (DBMS) manage only alphanumeric data but not multimedia data. In order to have a DBMS that can handle both alphanumeric data and multimedia data, one can either build a new system or modify an existing system. The decision was to build such a system on top of an existing system, namely INGRES, using the abstract data type (ADT) concept. Unfortunately the INGRES system used does not support ADT. As a result the Multimedia Database Management System (MDBMS) prototype must design data structures that would allow the capture and retrieval of the information relating to the data in the database. Further, to implement the ADT concept for the multimedia data, additional tables need to be created that would hold information relating to the multimedia data. This process of dealing with the management of information, generally referred to as catalog management, in the MDBMS prototype is a major part of this thesis. The design of the data structures and their applications are explained. In addition, to be able to insert data into the database, operations for the creation of tables and the insertion of the data are needed. These operations are not simple, single SQL statement. Because of the potential presence of multimedia data, the generation of multiple statements may be required from one simple user statement. The thesis also discusses the design and implementation of these operations.

The implementation of a visual language interface for an object-oriented multimedia database system

Abstract: This paper documents the ongoing implementation of the VILD visual language interface to the object-oriented multimedia database system, MDBMS. We set forth the infrastructure on which VILD has been developed, and describe in detail the three sections of the language system which have been completed: the Schema Editor to define the database, the Frame Editor to edit and enter data, and the Browser to view the data. We conclude with the query implementation of VILD.

OMEN - An Object-Oriented Database Management System for Non-Standard Database Applications

Abstract: Object-oriented Database Management Systems (ooDBMS) gain a lot of attention in the database research area, because they offer much promising facilities to support non-standard database applications like CAD/CAM, office automation, multimedia databases or data-intensive knowledge bases. Conventional database technology (i.e., relational or network) is not well-suited in these fields, because of their poor structural and behavioral modeling capabilities.

Multimedia database design and architecture in radiology communications

Abstract: Multimedia database is a fundamental component in the Multimedia Radiology Information System It provides mean by which different classes of documents (diagnostic reports, images, patient information, etc), involving several media (text, image, graphics, voice), are structured, represented, stored, manipulated and retrieved In this paper, we first present the requirements for a multimedia database along with the data model used to describe the radiology information and procedures Then, we describe our approach to the multimedia database design and architecture, and the corresponding prototype instance in terms of implementation and storage strategies Finally, we give a conclusion with an overview of the research undertaken for enhanced multimedia data management

Intelligent search and retrieval of a large multimedia knowledge base for the Hubble Space Telescope

Abstract: A document-retrieval assistant (DRA) in a microcomputer format is described which incorporates hypertext and natural language capabilities Hypertext is used to introduce an intelligent search capability, and the natural-language interface permits access to specific data without the use of keywords The DRA can be used to access and 'browse' the large multimedia database that is composed of project documentation from the HST

Mapping data schemas to MDBMS architecture layers

Abstract: The architecture of a multimedia database system (MDBMS) should directly reflect the characteristics of multimedia data on different abstraction levels. By distinguishing single-media objects, structurally composed multimedia objects, and multimedia objects with complex behavioral relationships, they identify three abstraction levels for multimedia objects. Appropriate data schemas are developed for each of these abstraction levels. The data schemas are then mapped in a straightforward manner to architectural layers of an MDBMS. Consequently, each architectural layer has to implement the functionality described by its corresponding data schema. In this way, MDBMS architecture can be regarded as derived from data schemas. >

Design and Implementation of a Multimedia DBMS. Retrieval Management

Abstract: : Current conventional Database Management Systems (DBMS) manage only alphanumeric data. However, data to be stored in the future is expected to include some multimedia form, such as images, graphics, sounds or signals. The structure and the semantics of the media data and the operations on that data are complex. It is not clear what requirements are needed in a DBMS to manage this kind of data. It is also not clear what is needed in the data model to support this kind of data; nor what the user interface should be for such a system. The goal of the Multimedia Database Management System project in the computer science department of the Naval Post Graduate School is to build into a Database Management System (DBMS) the capability to manage multimedia data, as well as the formatted data, and define operations on multimedia data. This thesis, focusing only on the media data of image and sound, first describes the operations of such a system, then discusses the general design of it, and finally outline the detailed design and implementation of the retrieval operation.

A caption-based natural-language interface handling descriptive captions for a multimedia database system

Abstract: : This research examined the grammar structure of descriptive English captions on multimedia data. The research was composed of three phases. The first phase was to investigate the grammar structure of example descriptive captions from a variety of subject domains. The second phase was to develop a set of domain independent binary grammar rules to be used in the Caption-Based Interface (CBI) which is a natural language interface for the Multimedia Database System. The third phase of the research was to implement and test the grammar rules in the CBI. The program was implemented in C-prolog on a Sun SPARC workstation. The testing phase also includes timing and memory comparisons between C-Prolog an interpretive programming language and a compiled version of the code using Quintus Prolog. This thesis was able to show that the grammar rules that were developed could correctly identify their intended structures. Another accomplishment of this thesis was to demonstrate that the CBI could parse 25 out of 30 example captions and that it could correctly handle some semantic interpretations of the parsed captions.
