  Hider, P.: Towards a sociology of KOS and more basic KO research.
  In: Knowledge organization. 47(2020) no.6, S.501-510.
  
  Abstract: It is suggested that the knowledge organization (KO) field places greater emphasis on basic research that examines the sociology of KO systems (KOS) and the broader, environmental reasons for the development of both formal and informal KOS. This approach is contrasted with applied KO, which focuses on the practical construction or improvement of specific KOS. The preponderance of applied research in the field of KO is confirmed, at least within the document-centric strand more closely aligned with library and information science, through a survey of articles in the Knowledge Organization journal published between 2009 and 2018. The survey utilized the Frascati Manual definitions for basic and applied research, and referenced Tennis's classification of KO research (2008). There is considerable potential for building on the critical tradition of KO, with various areas ripe for further sociological investigation. A sociology of KOS could also be accommodated in the popular KO approach of domain analysis.

  Hider, P.: ¬The search value added by professional indexing to a bibliographic database.
  In: Knowledge organization. 45(2018) no.1, S.23-32.
  
  Abstract: Gross et al. (2015) have demonstrated that about a quarter of hits would typically be lost to keyword searchers if contemporary academic library catalogs dropped their controlled subject headings. This article reports on an investigation of the search value that subject descriptors and identifiers assigned by professional indexers add to a bibliographic database, namely the Australian Education Index (AEI). First, a similar methodology to that developed by Gross et al. (2015) was applied, with keyword searches representing a range of educational topics run on the AEI database with and without its subject indexing. The results indicated that AEI users would also lose, on average, about a quarter of hits per query. Second, an alternative research design was applied in which an experienced literature searcher was asked to find resources on a set of educational topics on an AEI database stripped of its subject indexing and then asked to search for additional resources on the same topics after the subject indexing had been reinserted. In this study, the proportion of additional resources that would have been lost had it not been for the subject indexing was again found to be about a quarter of the total resources found for each topic, on average.

  Hider, P.: ¬The search value added by professional indexing to a bibliographic database.
  In: http://www.iskocus.org/NASKO2017papers/NASKO2017_paper_33.pdf [NASKO 2017, June 15-16, 2017, Champaign, IL, USA].
  
  Abstract: Gross et al. (2015) have demonstrated that about a quarter of hits would typically be lost to keyword searchers if contemporary academic library catalogs dropped their controlled subject headings. This paper reports on an analysis of the loss levels that would result if a bibliographic database, namely the Australian Education Index (AEI), were missing the subject descriptors and identifiers assigned by its professional indexers, employing the methodology developed by Gross and Taylor (2005), and later by Gross et al. (2015). The results indicate that AEI users would lose a similar proportion of hits per query to that experienced by library catalog users: on average, 27% of the resources found by a sample of keyword queries on the AEI database would not have been found without the subject indexing, based on the Australian Thesaurus of Education Descriptors (ATED). The paper also discusses the methodological limitations of these studies, pointing out that real-life users might still find some of the resources missed by a particular query through follow-up searches, while additional resources might also be found through iterative searching on the subject vocabulary. The paper goes on to describe a new research design, based on a before - and - after experiment, which addresses some of these limitations. It is argued that this alternative design will provide a more realistic picture of the value that professionally assigned subject indexing and controlled subject vocabularies can add to literature searching of a more scholarly and thorough kind.

  Hider, P.: ¬A critique of the FRBR user tasks and their modifications.
  In: Cataloging and classification quarterly. 55(2017) no.2, S.55-74.
  
  Abstract: The four FRBR user tasks have become widely accepted as functions of the library catalog, but there have been only sporadic discussions concerning their validity and sufficiency, despite their modification in the models subsequently presented in the FRAD, FRSAD, and draft FRBR-LRM reports. This article presents a critique of the four variant sets of user tasks, and proposes an extended set of six generic end-user tasks, applicable to both bibliographic and authority data: locate, collocate, connect, identify, select, and obtain. The article also outlines their interrelationships and suggests those tasks that may be particularly well supported by professional cataloging.

  Hider, P.: ¬The functional requirements for community information.
  In: Journal of documentation. 72(2016) no.1, S.81-102.
  
  Abstract: Purpose - The purpose of this paper is to consider the nature of community information (CI) and proposes a data model, based on the entity-relationship approach adopted in the Functional Requirements for Bibliographic Records (FRBR), which may assist with the development of future metadata standards for CI systems. Design/methodology/approach - The two main data structure standards for CI, namely the element set developed by the Alliance of Information and Referral Systems (AIRS) and the MARC21 Format for CI, are compared by means of a mapping exercise, after which an entity-relationship data model is constructed, at a conceptual level, based on the definitions of CI found in the literature. Findings - The AIRS and MARC21 data structures converge to a fair degree, with MARC21 providing for additional detail in several areas. However, neither structure is systematically and unambiguously defined, suggesting the need for a data model. An entity-relationship data modelling approach, similar to that taken in FRBR, yielded a model that could be used as the basis for future standards development and research. It was found to effectively cover both the AIRS and MARC21 element sets. Originality/value - No explicit data model exists for CI, and there has been little discussion reported about what data elements are required to support CI seeking.

  Hider, P.: ¬A survey of the coverage and methodologies of schemas and vocabularies used to describe information resources.
  In: Knowledge organization. 42(2015) no.3, S.154-163.
  
  Abstract: Riley's survey (2010) of metadata standards for cultural heritage collections represents a rare attempt to classify such standards, in this case according to their domain, community, function and purpose. This paper reports on a survey of metadata standards with particular functions, i.e. those of schemas and vocabularies, but that have been published online for any domain or community (and not just those of the cultural heritage sector). In total, 53 schemas and 328 vocabularies were identified as within scope, and were classified according to their subject coverage and the type of warrant used in their reported development, i.e. resource, expert or user warrant, or a combination of these types. There was found to be a general correlation between the coverage of the schemas and vocabularies. Areas of underrepresentation would appear to be the humanities and the fine arts, and, in the case of schemas, also law, engineering, manufacturing and sport. Schemas would appear to be constructed more by consulting experts and considering endusers' search behaviour; vocabularies, on the other hand, are developed more by considering the information resources themselves, or by combining a range of methods.

  Hider, P. ; Liu, Y.-H.: ¬The use of RDA elements in support of FRBR user tasks.
  In: Cataloging and classification quarterly. 51(2013) no.8, S.857-872.
  
  Abstract: Resource Description and Access (RDA) stipulates that certain "core" elements should always be included, where applicable, in bibliographic and authority records, due to their importance in supporting the user tasks defined in Functional Requirements for Bibliographic Records. However, the elements' relative importance has not been empirically tested. This study investigates which elements in bibliographic records are currently most used in a university library catalog, by means of think-aloud sessions conducted by expert and non-expert users, who were assigned sets of typical bibliographic tasks. The results indicate that, in this context at least, the most utilized elements are not all core.

  Hider, P.: Information resource description : creating and managing metadata.
  London : Facet Publ., 2012. XIX, 220 S.
  ISBN 978-1-85604-667-1
  
  Abstract: An overview of the field of information organization that examines resource description as both a product and process of the contemporary digital environment. This timely book employs the unifying mechanism of the semantic web and the resource description framework to integrate the various traditions and practices of information and knowledge organization. Uniquely, it covers both the domain-specific traditions and practices and the practices of the 'metadata movement' through a single lens - that of resource description in the broadest, semantic web sense. This approach more readily accommodates coverage of the new Resource Description and Access (RDA) standard, which aims to move library cataloguing into the centre of the semantic web. The work surrounding RDA looks set to revolutionise the field of information organization, and this book will bring both the standard and its model and concepts into focus.

  Hider, P.: ¬A comparison between the RDA taxonomies and end-user categorizations of content and carrier.
  In: Cataloging and classification quarterly. 47(2009) no.6, S.xx-xx.
  
  Abstract: Resource Description and Access (RDA) includes new lists of content and carrier types intended to replace the General Material Designations (GMDs) and Specific Material Designations (SMDs) of the Anglo-American Cataloguing Rules (AACR), and which represent taxonomies designed to facilitate searching on content and carrier attributes of resources. However, these taxonomies were not constructed through analysis of end-user categorizations, nor have they been tested on end-users. This study investigates how end-users categorize library resources by employing the free-listing technique, commonly employed by cognitive scientists and information architects. The results indicate that end-user categorizations of library resources may emphasize other facets, such as purpose, audience and extent, in addition to content and carrier, and also levels of the content and carrier facets other than those represented by the RDA terms.

  Hider, P. ; Tan, K.-C.: Constructing record quality measures based on catalog use.
  In: Cataloging and classification quarterly. 46(2008) no.4, S.338-361.
  
  Abstract: Approaches to the measurement of catalog record quality are discussed. The systematic application of specific evaluation criteria may be more reliable than expert opinion, if not necessarily more accurate, and the construction of an error weightings table based on empirical investigation into catalog use is described. Although this process proved to be complex, and involved significant methodological problems, it was shown to be readily achievable. As catalog use may in many cases be insufficiently uniform across libraries to allow for generic evaluation criteria, it is proposed that cataloging managers construct their own set by studying the impact that record quality has on the particular use of their own catalogs. Thus more empirical research into catalog use is advocated, in order to supplement expert opinion and to build toward a practice of evidence-based cataloging.

  Hider, P.: Familial authorship in the Anglo-American cataloging tradition.
  In: Cataloging and classification quarterly. 45(2007) no.2, S.65-82.
  
  Abstract: In the light of a proposal for names of families to be treated as a separate form of name heading in the forthcoming Resource Description and Access, this article examines the treatment of families in the Anglo-American descriptive cataloging tradition and the extent to which names of families have been assigned as non-subject access points. It contrasts manuscript catalogers' practice of assigning family name headings with the general binary division of personal and corporate names, and discusses how an expansion of the library definition of authorship, so as to accommodate the archival concept of provenance, may more readily allow for familial and other non-corporate group authors. It concludes by suggesting that a corporate and non-corporate group categorisation may be unnecessary, and that instead the corporate body class should be revised, so as to encompass all groups of persons.

  Hider, P.M.: Constructing an index of search goal redefinition through transaction log analysis.
  In: Journal of documentation. 63(2007) no.2, S.175-187.
  
  Abstract: Purpose - The purpose of this research is to discuss the methodological aspects of a study, the results of which are detailed in a second paper. Design/methodology/approach - Indices of search goal revision (or redefinition) were constructed based on the chronological coding of queries logged on the OCLC FirstSearch service. Queries within search sessions were coded according to their conceptual relationships, based on a set of rules designed to identify possible revisions of search goals, as well as strategic reformulations. Given the same user interface, similar types of user, and large datasets, it was assumed that the number of strategic reformulations would be reasonably uniform across databases, so that the indices could be regarded as indicators of relative amounts of goal revision. Findings - The reliability of the coding used to construct the indices of goal redefinition was tested through parallel coding, and confirmed. Differences between the indices for various databases, on the other hand, were found to be statistically significant, allowing for the conclusion that the indices were able to show differences in the amount of goal redefinition occurring, given the assumption of similar levels of strategic reformulations across databases. Originality/value - Transaction log analysis has mostly focused on syntactic issues; few analyses have examined the semantic content of queries or contextualised individual queries as part of an evolving search session. However, this paper shows that although transaction log analysis is a relatively indirect means of examining users' thoughts and intentions during their interaction with an information retrieval system, logs that provide sufficiently rich data may, in certain controlled situations, be used to provide deeper insights into information retrieval behaviour.

  Hider, P.M.: Search goal redefinition through user-system interaction.
  In: Journal of documentation. 63(2007) no.2, S.188-203.
  
  Abstract: Purpose - The purpose of this research is to examine search goal redefinition during users' interaction with information retrieval systems. Design/methodology/approach - The study utilized transaction logs from the OCLC FirstSearch service. Within each search session, logged queries were coded chronologically, according to their conceptual relationships, and indices of goal redefinition were constructed. Redefinition levels for different databases were compared, and certain features were isolated for examination as possible redefinition factors. Findings - The transaction log analysis showed that different databases induced goal redefinition to different extents and identified several factors which can contribute to goal redefinition, including the presence of abstracts and hyperlinking descriptors. On the other hand, no evidence was found to indicate that abstract length has much effect on redefinition, nor hit rate or retrievability of records. Practical implications - The research needs to be followed up using other methodologies and other information retrieval systems. A range of other possible factors affecting goal redefinition should be investigated. Originality/value - The paper shows that system feedback affects not only strategy, but also higher levels of information seeking behaviour interaction. This aspect of user-system interaction has rarely been researched. An index of goal redefinition and an interpretative form of transactional log analysis are put forward as means by which it may be investigated.

  Hider, P.: ¬A survey of continuing professional development activities and attitudes amongst catalogers.
  In: Cataloging and classification quarterly. 42(2006) no.2, S.35-58.
  
  Abstract: It has been widely recognised that MLS courses and on-the-job training need to be supplemented by continuing professional development (CPD), if catalogers are to fulfil their potential and remain in the field. The results of a questionnaire survey show that catalogers and other metadata specialists are undertaking a broad range of CPD activities, and would welcome more opportunities. They are especially keen on short courses, but also interested in more formal and longer-term programs, and are looking to upgrade their skills and knowledge in both traditional and emerging areas. While most think that their CPD efforts can advance their careers, many catalogers consider levels of support from employers and the profession to be less than adequate.

  Hider, P. ; Turner, S.: ¬The application of AACR2's rules for personal names in certain languages.
  In: Cataloging and classification quarterly. 43(2006) no.2, S.37-52.
  
  Abstract: Anglo-American Cataloguing Rules include special rules for personal name headings in certain languages under 22.21-22.28. This article investigates the extent to which four of these rules, pertaining to Indonesian, Malay, and Thai names, have been applied by catalogers contributing to the Australian National Bibliographic Database and discusses their value of these rules in the context of the general rules they supplement. It was found that many headings were not compliant with the rules, especially those resulting from English-language cataloging. Given catalogers' apparent difficulty in applying the special rules, it is recommended that they be deleted, that the general rules be further generalized, and that more use is made of relevant linguistic and cultural resources.

  Hider, P.: Developing courseware for cataloguing.
  In: Journal of education for library and information science. 41(2000) no.3, S.187-196.
  
  Abstract: This article describes the development and application of the Cat with Moose courseware in the cataloging curricula at Temasek Polytechnic, Singapore, which offers diploma-level, paraprofessional training in library and information service (LIS). The aim of Cat with Mouse is to provide students with practice in cataloging a range of materials, both print and nonprint, in an online environment. The courseware checks the entries as students progress through the record template and allows them to simultaneously consult windows containing the relevant sources of information. The product is designed to be used as a revision tool and is accessible to students through the Internet. The development team revised a prototype version after feedback was collected by means of a questionnaire. Most students found the courseware useful and that it made revision easier. It is argued that, as an assessment tool, Cat with Mouse is also reliable and valid, and that the distinctive benefits the courseware offers has made the investment in the project worthwhile.
