Abstract

The focus of this paper is the provision of terminology- and classification-based terminologies interoperability data via web services, initially using interoperability data based on the use of a Dewey Decimal Classification (DDC) spine, but with an aim to explore other possibilities in time, including the use of other spines. The High-Level Thesaurus Project (HILT) Phase IV developed pilot web services based on SRW/U, SOAP, and SKOS to deliver machine-readable terminology and crossterminology mappings data likely to be useful to information services wishing to enhance their subject search or browse services. It also developed an associated toolkit to help information services technical staff to embed HILT-related functionality within service interfaces. Several UK information services have created illustrative user interface enhancements using HILT functionality and these will demonstrate what is possible. HILT currently has the following subject schemes mounted and available: DDC, CAB, GCMD, HASSET, IPSV, LCSH, MeSH, NMR, SCAS, UNESCO, and AAT. It also has high level mappings between some of these schemes and DDC and some deeper pilot mappings available.

Abstract

The JISC-funded HILT project is looking to make contact with staff in information services or projects interested in helping it test and refine its developing terminology services. The project is currently working to create pilot web services that will deliver machine-readable terminology and cross-terminology mappings data likely to be useful to information services wishing to extend or enhance the efficacy of their subject search or browse services. Based on SRW/U, SOAP, and SKOS, the HILT facilities, when fully operational, will permit such services to improve their own subject search and browse mechanisms by using HILT data in a fashion transparent to their users. On request, HILT will serve up machine-processable data on individual subject schemes (broader terms, narrower terms, hierarchy information, preferred and non-preferred terms, and so on) and interoperability data (usually intellectual or automated mappings between schemes, but the architecture allows for the use of other methods) - data that can be used to enhance user services. The project is also developing an associated toolkit that will help service technical staff to embed HILT-related functionality into their services. The primary aim is to serve JISC funded information services or services at JISC institutions, but information services outside the JISC domain may also find the proposed services useful and wish to participate in the test and refine process.

Abstract

My presentation is about the HILT, High Level Thesaurus Project, which is looking, very roughly speaking, at how we might deal with interoperability problems relating to cross-searching distributed services by subject. The aims of HILT are to study and report on the problem of cross-searching and browsing by subject across a range of communities, services, and service or resource types in the UK given the wide range of subject schemes and associated practices in place

Abstract

This article provides an overview of the work carried out by the HILT Project <http://hilt.cdlr.strath.ac.uk> in making recommendations towards interoperable subject access, or cross-searching and browsing distributed services amongst the archives, libraries, museums and electronic services sectors. The article details consensus achieved at the 19 June 2001 HILT Workshop and discusses the HILT Stakeholder Survey. In 1999 Péter Jascó wrote that "savvy searchers" are asking for direction. Three years later the scenario he describes, that of searchers cross-searching databases where the subject vocabulary used in each case is different, still rings true. Jascó states that, in many cases, databases do not offer the necessary aids required to use the "preferred terms of the subject-controlled vocabulary". The databases to which Jascó refers are Dialog and DataStar. However, the situation he describes applies as well to the area that HILT is researching: that of cross-searching and browsing by subject across databases and catalogues in archives, libraries, museums and online information services. So how does a user access information on a particular subject when it is indexed across a multitude of services under different, but quite often similar, subject terms? Also, if experienced searchers are having problems, what about novice searchers? As information professionals, it is our role to investigate such problems and recommend solutions. Although there is no hard empirical evidence one way or another, HILT participants agree that the problem for users attempting to search across databases is real. There is a strong likelihood that users are disadvantaged by the use of different subject terminology combined with a multitude of different practices taking place within the archive, library, museums and online communities. Arguably, failure to address this problem of interoperability undermines the value of cross-searching and browsing facilities, and wastes public money because relevant resources are 'hidden' from searchers. HILT is charged with analysing this broad problem through qualitative methods, with the main aim of presenting a set of recommendations on how to make it easier to cross-search and browse distributed services. Because this is a very large problem composed of many strands, HILT recognizes that any proposed solutions must address a host of issues. Recommended solutions must be affordable, sustainable, politically acceptable, useful, future-proof and international in scope. It also became clear to the HILT team that progress toward finding solutions to the interoperability problem could only be achieved through direct dialogue with other parties keen to solve this problem, and that the problem was as much about consensus building as it was about finding a solution. This article describes how HILT approached the cross-searching problem; how it investigated the nature of the problem, detailing results from the HILT Stakeholder Survey; and how it achieved consensus through the recent HILT Workshop.

Abstract

The HILT High Level Thesaurus Project aims to study and report an the problern of cross-searching and browsing by subject across a range of communities, services, and service or resource types in the UK given the wide range of subject schemes and associated practices in place in the communities in question (Libraries, Museums, Archives, and Internet Services) and taking the international context into consideration. The paper reports an progess to date, focusing particularly an the inter-community consensus reached at a recent Stakeholder Workshop.

Abstract

Purpose - To report on initial work carried out on a Metadata Options Appraisal undertaken for the Loch Lomond and Trossachs National Park in the context of plans to create and manage complex digital objects called Interpretive Journeys, PDA-based multimedia guides to Park tours. Design/methodology/approach - After some initial work, a phased approach was adopted. In Phase I (reported here), metadata schema for managing structurally complex digital objects were researched to provide a range of appropriate options. Their characteristics were then matched against the Park's general requirements as determined through discussions with staff and an examination of relevant documentation. Findings - It was determined that the METS metadata schema met Park requirements for managing Interpretive Journeys at a general level and could be used both, to inform the development of the planned Digital Asset Management System (an early priority), and to act as the main basis of a framework for determining a detailed metadata solution for the Park. Research limitations/implications - Further work is required in Phase II to determine the detailed metadata requirement for the Park. Practical implications - A useful guide to dealing with a range of management and metadata issues associated with managing complex digital objects, and to managing projects where guidance on metadata requirements is needed before the objects to be described are available. Originality/value - This paper offers an introduction to the management and metadata issues raised by Interpretive Journeys and digital composites of similar complexity, and an indication of how METS addresses these at a general level.
