Abstract

This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

Abstract

A 1 day seminar was held in Aug 1997, in Synney, Australia, sponsored by the Information science Section of the australia Library and Information Association, on metadata. It focused on building a conceptual framework for metadata. The National Library is developing PANDORA (Preserving and Accessing Networked documentary Resources of Australia) an electronic archive designed to provide long term access to significant Australian online publications. An architecture for access to government information has been developed. The Distributed System Technology Centre's Resource Discivery Project Unit has developed an information presentation tool called HyperIndex and a meta-data searcher called HotOIL

Abstract

States that heterogeneous project groups today may be expected to use the mechanisms of the Web for sharing information. Metadata has been proposed as a mechanism for expressing the semantics of information and, hence, facilitate information retrieval, understanding and use. Presents an approach to sharing information which aims to use a semantic modeling language as the basis for expressing the semantics of information and designing metadata schemes. Functioning on the borderline between human and computer understandability, the modeling language would be able to express the semantics of published Web documents. Reporting on work in progress, presents the overall framework and ideas

Abstract

Metadata provides the human- and machine-accessible gateway to data, improves data to information, and provides the semantic context within which knowledge can be induced from information. Metadata is the means for using together scientific data from heterogeneous sources. A CRIS commonly holds data which, while useful in itself, commonly is also metadata describing more detailed data and information an projects, persons, organizations, products of R&D (patents, products, publications) equipment used for R&D and R&D funding. It is important, therefore, to classify the metadata formats used in various scientific repositories in order to understand their scope and interoperability, and their relationship to CERIF representing CRISs. Metadata formats are reviewed according to intention, abstraction level and technology criteria. The place of CERIF in CRISs in this wider sense (including scientific repositories) is considered and compared with other metadata models and formats. The superiority of CERIF (in formalism and flexibility) is demonstrated.

Abstract

For this fourth column in the IT I-V (information technology interview) series participants actively engaged or interested in the metadata harvesting protocol of the open archives initiative were interviewed. The metadata harvesting initiative targets information generally inaccessible through standard browser searches, such as information stored in databases or within library online public access catalogs. We selected this topic as an information technology-based initiative with the potential to provide information about the usefulness of metadata: in particular the Dublin Core metadata standard, but also about other metadata standards, as the protocol design supports community-specific schemas as well. The group interviewed represents developers, commercial information providers, funders, and members of the scholarly publishing community. Along with learning about the interests and concerns of each of these stakeholders and about specific applications of the protocol, we identify potential questions that will ultimately need to be addressed.

Abstract

The task of an information architect is to create web sites where users can actually find the information they are looking for. As the ocean of information rises and leaves what we seek ever more deeply buried in what we don't seek, this discipline becomes ever more relevant. Information architecture involves many different aspects of web site creation and organization, but its principal tools are information organization techniques developed in other disciplines. Most of these techniques come from library science, such as thesauri, taxonomies, and faceted classification. Topic maps are a relative newcomer to this area and bring with them the promise of better-organized web sites, compared to what is possible with existing techniques. However, it is not generally understood how topic maps relate to the traditional techniques, and what advantages and disadvantages they have, compared to these techniques. The aim of this paper is to help build a better understanding of these issues.

Abstract

Purpose - This paper aims to forecast the changing roles of librarians - especially catalogers and metadata specialists - in today's technology-driven research, teaching, and learning environments, in which information seekers behave more and more self-sufficiently and move well beyond library collections in their pursuit of information. Design/methodology/approach - Places the roles of librarians and library collections in the larger context of knowledge management and campus information network processes, which occur in every knowledge community, with or without a library. Explores and provides examples of how knowledge creators can collaborate with information technology experts and librarians to transform how faculty members teach and conduct research; how students learn; and how libraries support these activities. Findings - Librarians need to make their collections and services much more visible through human and technological interconnections and greatly improved delivery of information content. Metadata and metadata specialists are strategic assets for libraries, but the service model for cataloging faces critical challenges. Two tables list these challenges and the implications for metadata specialists. Originality/value - Offers new observations and insights into how librarians can continue to contribute to saving information seekers' time and advancing the state of knowledge in the increasingly interconnected world of the web. Drawing from the larger context of the global infosphere, information-seeking behavior, and changing roles for library collections and information systems, forecasts the role of metadata and metadata specialists in libraries.

Abstract

Metadata systems are concerned with the management of data which describes other data (datasets, catalogues, or actual database management systems) and are presently the subject of intensive research. Metadata systems can be used to store richly detailed forms of information, perform seamless wide ranging searches of information distributed across networks, and to integrate information stored in disparate repositories. Describes a model design and methods of implementation derived from the experience of the Leicester University Metadata Project. The approach utilizes the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services. Feature of the class of design is flexibility or implementation, with the ability to provide a coherent metadata system functioning above heterogeneous autonomous distributed databases

Abstract

Information professions identified the need for a set of standard metadata almost as soon as the WWW became a reality. Several initiatives have already identified the types of bibliographic information that would be necessary to describe and locate an electronic publication. The descriptors identified in the OCLC/NCSA Dublin Core are combined with those assembled by the Coalition of Networked Information and the Internet Engineering Task force to produce a list of electronic citation elements. Advocates embedding these citation elements within electrinic documents through the use of HTML<META>tags and other markup techniques. There is also a call to cataloguing librarians to contribute their expertise in information resources management to document being prepared for the WWW in order to influence the quality of electronic publication from the insides

Abstract

Metadata is a term to describe the information required to documents the characteristics of information contained within databases. Describes the elements that make up metadata. A number of software tools exist to help apply document management principles to electronic records but they have, so far, been inadequately applied. Describes 2 initiative currently under way to develop software to automate many records management functions. Understanding document management principles as applied to electronic records are vital to records managers
