Abstract

With the proliferation of digitized resources accessible internationally via Internet and Intranet knowledge bases and a pressing need to develop more sophisticated tools for the identification and retrieval of electronic resources, both general purpose and domain-specific metadata schemes have assumed a particular prominence. This has resulted in a growing number of online repositories that must be accessed using terminology that would be considered unfamiliar to most searchers. Assuming that a natural language "gateway" requiring no prior knowledge of specific metadata tagging could facilitate cross-repository searching, end-users were engaged in focus group testing of a "namespace" of common categories derived from nine metadata schemes. Findings and their implications within an international context are presented.

Abstract

With the explosion of digitized resources accessible via networked information systems, and the corresponding proliferation of general purpose and domain-specific schemes, metadata have assumed a special prominence. While recent work emanating from the World Wide Web Consortium (W3C) has focused on the Resource Description Framework (RDF) to support the interoperability of metadata standards - thus converting metatags from diverse domains from merely "machine-readable" to "machine-understandable" - the next iteration, to "human-understandable," remains a challenge. This apparent gap provides a framework for three-phase research (Howarth, 1999) to develop a tool which will provide a "human-understandable" front-end search assist to any XML-compliant metadata scheme. Findings from phase one, the analyses and mapping of seven metadata schemes, identify the particular challenges of designing a common "namespace", populated with element tags which are appropriately descriptive, yet readily understood by a lay searcher, when there is little congruence within, and a high degree of variability across, the metadata schemes under study. Implications for the subsequent design and testing of both the proposed "metalevel ontology" (phase two), and the prototype search assist tool (phase three) are examined

Abstract

Given the paucity of research addressing client preferences for metadata content and display in knowledge access systems, a three-year study involving a sample of Canadian public and academic libraries and their end-users, was undertaken. Gaps between user preferences and the availability and presentation of metadata elements in some current Canadian web-based knowledge access systems were identified. Ideal displays were subsequently prototyped and evaluated. Overall, end-users favoured systems containing brief, concise, and focused metadata elements, restricted to a one-screen, uncluttered display, and enhanced by a variety of hierarchical, associative, and equivalent relationship links.

Abstract

Even as the number of Web-enabled resources and knowledge repositories continues its unabated climb, both general purpose and domain-specific metadata schemas are in vigorous development. While this might be viewed as a promising direction for more precise access to disparate metadata-enabled resources, semantically-oriented tools to facilitate cross-domain searching by end-users unfamiliar with structured approaches to language or particular metadata schema conventions have received little attention. This paper describes findings from a focus group assessment of a natural language "gateway" previously derived from mapping, then categorizing terminology from nine metadata schemas. Semantic ambiguities identified in relation to three core metadata elements, namely, "Names", "Title", and "Subject", are discussed relative to data collection techniques employed in the research. Implications for further research, and particularly that pertaining to the design of an Interlingua gateway to multilingual, metadata-enabled resources, are addressed.
