Collaborative tagging as a knowledge organisation and resource discovery tool

Purpose – The purpose of the paper is to provide an overview of the collaborative tagging phenomenon and explore some of the reasons for its emergence.Design/methodology/approach – The paper reviews the related literature and discusses some of the problems associated with, and the potential of, collaborative tagging approaches for knowledge organisation and general resource discovery. A definition of controlled vocabularies is proposed and used to assess the efficacy of collaborative tagging. An exposition of the collaborative tagging model is provided and a review of the major contributions to the tagging literature is presented.Findings – There are numerous difficulties with collaborative tagging systems (e.g. low precision, lack of collocation, etc.) that originate from the absence of properties that characterise controlled vocabularies. However, such systems can not be dismissed. Librarians and information professionals have lessons to learn from the interactive and social aspects exemplified by colla...

Taking stock of open access: progress and issues

Purpose - Aims at providing a broad overview of some of the issues emerging from the growth in open access publishing, with specific reference to the use of repositories and open access journals. Design/methodology/approach - A paper largely based on specific experience with institutional repositories and the internationally run E-library and information science (LIS) archive. Findings - The open access initiative is dramatically transforming the process of scholarly communication bringing great benefits to the academic world with an, as yet, uncertain outcome for commercial publishers. Practical implications - Outlines the benefits of the open access movement with reference to repositories and open access journals to authors and readers alike and gives some food for thought on potential barriers to the complete permeation of the open access model, such as copyright restrictions and version control issues. Some illustrative examples of country-specific initiatives and the international E-LIS venture are given. Originality/value - An attempt to introduce general theories and practical implications of the open access movement to those largely unfamiliar with the movement.

Challenges and issues in terminology mapping: a digital library perspective

Purpose – In light of information retrieval problems caused by the use of different subject schemes, this paper provides an overview of the terminology problem within the digital library field. Various proposed solutions are outlined and issues within one approach – terminology mapping are highlighted.Design/methodology/approach – Desk‐based review of existing research.Findings – Discusses benefits of the mapping approach, which include improved retrieval effectiveness for users and an opportunity to overcome problems associated with the use of multilingual schemes. Also describes various drawbacks such as the labour intensive nature and expense of such an approach, the different levels of granularity in existing schemes, and the high maintenance requirements due to scheme updates, and not least the nature of user terminology.Originality/value – General review of mapping techniques as a potential solution to the terminology problem.

Digital Natives and Specialised Digital Libraries: A Study of Europeana Users

The alignment of user needs with the technical capabilities of modern digital libraries is an area attracting the interest of researchers and practitioners. Europeana, conceived with the intention of offering a single access point to European cultural heritage, has been developed in recent years with a continuous effort to identify and respond to the needs of a range of users. This paper presents a study of two user communities – young people and the general public. The study, conducted between October 2009 and January 2010, comprised a series of focus groups and media labs in Bulgaria, Italy, the Netherlands and the UK. A distinctive aspect of this study is that it combines questionnaire-based and verbal feedback gathered from users with evidence of user actions whilst undertaking a well-defined task. The paper presents the context and the methodology of the study, and some of the data gathered within the study which helps to understand better the attitude of digital natives towards specialised digital libraries. The data analysis supports several conclusions: specialised digital libraries require strong advocacy to target the “digital natives” generation which tends to prefer general purpose search engines to specialised resources; young users are confident that they know how to use advanced search yet there is little evidence of their applying these skills in contrast to general public users; the perception of digital libraries differs in groups from different countries. The study contributes to the better understanding of some behavioural characteristics of users of digital libraries.

Analysis of equivalence mapping for terminology services

This paper assesses the range of equivalence or mapping types required to facilitate interoperability in the context of a distributed terminology server. A detailed set of mapping types were examined, with a view to determining their validity for characterizing relationships between mappings from selected terminologies (AAT, LCSH, MeSH, and UNESCO) to the Dewey Decimal Classification (DDC) scheme. It was hypothesized that the detailed set of 19 match types proposed by Chaplan in 1995 is unnecessary in this context and that they could be reduced to a less detailed conceptually-based set. Results from an extensive mapping exercise support the main hypothesis and a generic suite of match types are proposed, although doubt remains over the current adequacy of the developing Simple Knowledge Organization System (SKOS) Core Mapping Vocabulary Specification (MVS) for inter-terminology mapping.

Multiple terminologies: an obstacle to information retrieval

An issue currently at the forefront of digital library research is the prevalence of disparate terminologies and the associated limitations imposed on user searching. It is thought that semantic interoperability is achievable by improving the compatibility between terminologies and classification schemes, enabling users to search multiple resources simultaneously and improve retrieval effectiveness through the use of associated terms drawn from several schemes. This column considers the terminology issue before outlining various proposed methods of tackling it, with a particular focus on terminology mapping.

Thesauri: practical guidance for construction

Purpose – With the growing recognition that thesauri aid information retrieval, organisations are beginning to adopt, and in many cases, create thesauri. This paper offers some guidance on the construction process.Design/methodology/approach – An opinion piece with a practical focus, based on recent experiences gleaned from consultancy work.Findings – A number of steps can be taken to ensure any thesaurus under construction is fit for purpose. Due consideration is therefore given to aspects such as term selection, structure and notation, thesauri standards, software and Web display issues, thesauri evaluation and maintenance. This paper also notes that creating new subject schemes from scratch, however attractive, contributes to the plethora of terminologies currently in existence and can limit user searching within particular contexts. The decision to create a “new” thesaurus should therefore be taken carefully and observance of standards is paramount.Practical implications – This paper offers advice to ...

Subject searching requirements: the HILT II experience

The HILT Phase II project aimed to develop a pilot terminologies server with a view to improving cross‐sectoral information retrieval. In order to inform this process, it was first necessary to examine how a representative group of users approached a range of information‐related tasks. This paper focuses on exploratory interviews conducted to investigate the proposed ideal and actual strategies of a group of 30 users in relation to eight separate information tasks. In addition, users were asked to give examples of search terms they may employ and to describe how they would formulate search queries in each scenario. The interview process undertaken and the results compiled are outlined, and associated implications for the development of a pilot terminologies server are discussed.

HILT IV: subject interoperability through building and embedding pilot terminology web services

A report of work carried out within the JISC-funded HILT Phase IV project, the paper looks at the projects context against the background of other recent and ongoing terminologies work, describes its outcome and conclusions, including technical outcomes and terminological characteristics, and considers possible future research and development directions. The Phase IV project has taken HILT to the point where the launch of an operational support service in the area of subject interoperability is a feasible option and where both investigation of specific needs in this area and practical collaborative work are sensible and feasible next steps. Moving forward requires detailed work, not only on terminology interoperability and associated service delivery issues, but also on service and end user needs and engagement, service sustainability issues, and the practicalities of interworking with other terminology services and projects in UK, Europe, and global contexts.
