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

Web search engines are beginning to offer access to multimedia searching, including audio, video and image searching. In this paper we report findings from a study examining the state of multimedia search functionality on major general and specialized Web search engines. We investigated 102 Web search engines to examine: (1) how many Web search engines offer multimedia searching, (2) the type of multimedia search functionality and methods offered, such as "query by example", and (3) the supports for personalization or customization which are accessible as advanced search. Findings include: (1) few major Web search engines offer multimedia searching and (2) multimedia Web search functionality is generally limited. Our findings show that despite the increasing level of interest in multimedia Web search, those few Web search engines offering multimedia Web search, provide limited multimedia search functionality. Keywords are still the only means of multimedia retrieval, while other methods such as "query by example" are offered by less than 1% of Web search engines examined.

Abstract

Traditional query methods are good at retrieving items an the basis of a precise specification, but they are not useful when the user wants to explore an information base in order to find interesting items. Dynamic Taxonomies were recently proposed for guided browsing and retrieval from heterogeneous information bases. We discuss their application to multimedia information bases and provide an example of interaction.

Abstract

Multimedia is proliferating on Web sites, as the Web continues to enhance the integration of multimedia and textual information. In this paper we examine trends in multimedia Web searching by Excite users from 1997 to 2001. Results from an analysis of 1,025,910 Excite queries from 2001 are compared to similar Excite datasets from 1997 to 1999. Findings include: (1) queries per multimedia session have decreased since 1997 as a proportion of general queries due to the introduction of multimedia buttons near the query box, (2) multimedia queries identified are longer than non-multimedia queries, and (3) audio queries are more prevalent than image or video queries in identified multimedia queries. Overall, we see multimedia Web searching undergoing major changes as Web content and searching evolves.

Abstract

Reviews the current state of the art in the field of electronic publishing of periodical articles in full text, with particular reference to the experiences of Elsevier Science. Distinguishes between 4 types of full text electronic publishing: bibliographic data, for example CAPCAS, with SGML type electronic bibliographic records for articles in Elsevier journals; electronic access to an existing periodical on a single title basis, similar to the way in which Elsevier provides access to articles in the well established printed periodical Nuclear Physics; enhancement of an existing periodical through expanded hypertext links, in the same way that Immunology Today Online is provided with value added features impossible to emulate in a printed periodical; and the TULIP model, an Elsevier initiative which enables large scale full text document delivery of electronic periodicals via unedited ASCII full text created by OCR and cover to cover 300 dpi bitmapped page images. Pays tribute to other initiatives in the field, including: document delivery services such as UnCover and the British Library's Inside Information; Digital Libraries Initiative; Informedia Digital Video Library Project; Stanford Integrated Digital Library Project; California University at Berkeley Digital Library Project and Alexandria Digital Library Project. Discusses the future of the information and publishing industries in the light of these developments, noting the implications and problems likely to be encountered and the opportunities for new, multimedia publications
