Designing a semantically rich visual interface for cultural digital libraries using the UNEsCO multilingual thesaurus

User evaluation of a pilot terminologies server for a distributed multi-scheme environment

The present paper reports on a user-centred evaluation of a pilot terminology service developed as part of the High Level Thesaurus (HILT) project at the Centre for Digital Library Research (CDLR) in the University of Strathclyde in Glasgow. The pilot terminology service was developed as an experimental platform to investigate issues relating to mapping between various subject schemes, namely Dewey Decimal Classification (DDC), Library of Congress Subject Headings (LCSH), the Unesco thesaurus, and the MeSH thesaurus, in order to cater for cross-browsing and cross-searching across distributed digital collections and services. The aim of the evaluation reported here was to investigate users' thought processes, perceptions, and attitudes towards the pilot terminology service and to identify user requirements for developing a full-blown pilot terminology service

Explore the Stacks: A System for Exploration in Large Digital Libraries

Providing access to large digital library collections to novice users requires novel interfaces that are not built around the concept of search, as novice users frequently struggle to formulate appropriate queries. This paper presents the "Explore the Stacks" system, which provides a novel, browsing-focused interface for exploring digital library collections that is applicable to Big Data scale digital libraries. The system is demonstrated using a collection of approximately one million book illustrations provided by the British Library

Folks Thesauri or Search Thesauri: Why Semantic Search Engines Need Folks Thesauri?

The term ‘folks thesaurus’ was coined as a combination of ‘folks’ and ‘thesaurus’. A folks thesaurus puts terms into context by defining a variety of semantic relationships among the thesaurus terms. The objective of this study is to propose and present a conceptual basis from which it will be possible to build a folks thesaurus. The folks thesaurus takes its terminology and usage from a variety of sources (e.g., users' search queries, traditional thesauri, Wikipedia categories, folksonomies, social tagging, hashtags, and log file analysis of search engines). Folks thesaurus describing subject content can play a vital role in supporting web indexing and information retrieval. Folks thesauri are useful in bridging the gap that exists between the concepts presented by authors and the conceptual terms presented by a user/searcher. Folks thesaurus limits the terms available and increases the possibility that the query will use appropriate terms. If the folks thesaurus has structure in the form of associative or hierarchical tree structure and semantic relationships such as broader terms (BT), narrower terms (NT) or related terms (RT), these may also help the user in navigation through hierarchical semantic relationships and finding an appropriate query expression. If a query is too inclusive, then narrower terms may be substituted to refine the query. On the other hand, a query returning too few results can be broadened through the substitution of broader terms. Related terms may also be an aid in navigation and query construction

Multilingual query expansion in the Svemed+ bibliographic database : a case study

SveMed+ is a bibliographic database covering Scandinavian medical journals. It is produced by the University Library of Karolinska Institutet in Sweden. The bibliographic references are indexed with terms from the Medical Subject Headings (MeSH) thesaurus. The MeSH has been translated into several languages including Swedish, making it suitable as the basis for multilingual tools in the medical field. The data structure of SveMed+ closely mimics that of PubMed/MEDLINE. Users of PubMed/MEDLINE and similar databases typically expect retrieval features that are not readily available off-the-shelf. The SveMed+ interface is based on a free text search engine (Solr) and a relational database management system (Microsoft SQL Server) containing the bibliographic database and a multilingual thesaurus database. The thesaurus database contains medical terms in three different languages and information about relationships between the terms. A combined approach involving the Solr free text index, the bibliographic database and the thesaurus database allowed the implementation of functionality such as automatic multilingual query expansion, faceting and hierarchical explode searches. The present paper describes how this was done in practice.NoneAccepte

Retrieval features for online databases: common, unique, and expected

The aims of this study were to identify the retrieval features for online databases; difficulties faced by users; and retrieval features expected by users. A total of 25 databases were surveyed and 40 users were interviewed after the training sessions. Common retrieval features included Boolean operators,phrase searching, match of exact words or phrases, field specific and limit fields searches, truncation, and wildcard. Even though features are offered in many systems, their interpretation andimplementation are different. Unique features included lateral searching, density and frequency of terms, reference link, and searching via table of content. The expected features includedrelevance feedback and term weighting other than those already offered by ACM Digital Library and IEEE Xplore. Such expectations were influenced by the users’ background in ICT. Difficulties included application of the retrieval features in searching. Database providers must include the expected features, synonyms linked to terms in the thesaurus, and extensive search examples

The past, present, and future of accessible tourism research: A bibliometric analysis using the Scopus database

At present, it is estimated that there are more than 1 billion people with some type of disability worldwide. Against this background, it is important to reconceive every life sphere and activity to ensure the inclusion, participation and equal opportunity of people with disabilities and to promote respect for their capacities and desires as people. The tourism sector is leaving large segments of global society behind. Tourism companies need more training and guidance to address the requirements of tourists who have specific needs or require certain types of support. This study aims to analyze and map the progress in scientific research on accessible tourism. To achievethis objective, this paper presents a bibliometric analysis of scientific paperson accessible tourism published in the Scopus database between 1997 and 2021. The study used the VOSviewer and CiteSpace software to map and visualize publication trends within this field. A total of 254 articles were included, of which 95.6% were original research. These studies were published in 52 countries. Australia is among the countries with high researchproductivity in this field. The most productive journals are Tourism Management and Sustainability (Switzerland), and the most prominent author is Simon Darcy. The analysis of keywords allows us to continually review the opportunities that new information and communication technologies(specifically smartphones and virtual reality) offer for the future development of the accessible tourism sector.Peer Reviewe

Geteiltes Wissen und Retrieval: Ein Prozessmodell zur Unterstützung kollaborativer Suchprozesse

Hoher Wettbewerbsdruck wird für Unternehmen auf allen Ebenen immer stärker spürbar. Noch vor einigen Jahren gab es ganze Bereiche in Wirtschaft, Handel und öffentlicher Verwaltung, die bestenfalls auf eine technisch-inhaltliche Optimierung der jeweiligen Produkte und Leistungen orientiert waren. Dies hat weitgehend einer markt- und wettbewerbsorientierten Ausrichtung Platz gemacht, Innensicht wird durch verstärkte Außensicht ergänzt
