Abstract

Purpose - Aims to present a comparison and evaluation of four user interfaces of web-based e-journals (Science Direct, ProQuest Direct, EBSCO Host and Emerald). Design/methodology/approach - The systems were assessed in an expert study according to accepted guidelines regarding user friendliness and functionality. User friendliness features studied were: language(s) and type(s) of interface; navigation options; personalization; and screen features. Functions inspected were: database selection; query formulation and reformulation; results manipulation; and help. Findings - Many similarities were found, but some differences among the systems were also discovered and analysed in detail. The greatest differences were found in the area of query formulation, and between the interface languages and types. Research limitations/implications - The user interfaces of four full-text IR systems offering e-journals which are accessible at the University of Ljubljana are surveyed. Practical implications - The interfaces are surveyed and assessed in order to discover their characteristics, advantages, and potential downsides and/or mistakes which may hinder use by an average user. Originality/value - The study serves as a basis for a subsequent user study of the information behaviour of the users of these systems.

Abstract

This article presents one part of a wider study, performed at the Department of library and information science and book studies (LIS & BS) at the University of Ljubljana (UL). The study investigated the perceptions of user friendliness of information-retrieval systems (IRS) and the role of individual characteristics of users in these perceptions. Based on an expert study, a user study with 61 postgraduate students of the UL was performed. Three interfaces of e-journals were studied: Science Direct, Proquest Direct, and Ebsco Host. Questionnaires and observations were used for data collection. The users'perceptions of user friendliness and of importance of auxiliary functions were investigated. Also, the connections between these perceptions and the users'individual characteristics were identified. Three sets of individual characteristics were included: approaches to studying, thinking styles, and hemisphere leanings. In connection with the dimensions of individual characteristics, very different perceptions of user friendliness were expressed. Some dimensions of individual characteristics were also found to be connected to the users'academic areas. It is shown that participants from different academic areas have different requirements and perceptions of user friendliness. The results of the study are relevant for the design of the user interfaces of disciplinary IR systems. They also have implications for other areas, for example, user education and training.

Abstract

This proposal presents the methodology of indexing with images suggested by De Brito and Caribé (2015). The imagetic model is used as a compatible mechanism with FRSAD for a global information share and use of subject data, both within the library sector and beyond. The conceptual model of imagetic indexing shows how images are related to topics and 'key-images' are interpreted as nomens to implement the FRSAD model. Indexing with images consists of using images instead of key-words or descriptors, to represent and organize information. Implementing the imaged navigation in OPACs denotes multiple advantages derived from this rethinking the OPAC anew, since we are looking forward to sharing concepts within the subject authority data. Images, carrying linguistic objects, permeate inter-social and cultural concepts. In practice it includes translated metadata, symmetrical multilingual thesaurus, or any traditional indexing tools. iOPAC embodies efforts focused on conceptual levels as expected from librarians. Imaged interfaces are more intuitive since users do not need specific training for information retrieval, offering easier comprehension of indexing codes, larger conceptual portability of descriptors (as images), and a better interoperability between discourse codes and indexing competences affecting positively social and cultural interoperability. The imagetic methodology deploys R&D fields for more suitable interfaces taking into consideration users with specific needs such as deafness and illiteracy. This methodology arouse questions about the paradigms of the primacy of orality in information systems and pave the way to a legitimacy of multiple perspectives in document indexing by suggesting a more universal communication system based on images. Interdisciplinarity in neurosciences, linguistics and information sciences would be desirable competencies for further investigations about he nature of cognitive processes in information organization and classification while developing assistive KOS for individuals with communication problems, such autism and deafness.

Abstract

Compares and evaluates the functional capabilities and interface characteristics of OPACs from the user oriented perspective, using a systematic framework. OPACs of OhioLINK and its 16 member libraries are the object of the investigation. The interfaces used 6 system software but showed a variety of features in access to OPACs, operational control, access points, search formulation control, and user assistance. Interface design alternatives are identified and qualitatively analyzed

Abstract

Purpose - The paper aims to provide some insight into mental models of the bibliographic universe and how they compare with functional requirements for bibliographic records (FRBR) as a conceptual model of the bibliographic universe. Design/methodology/approach - To get a more complete picture of the mental models, different elicitation techniques were used. The three tasks of the paper were: card-sorting, concept mapping and comparison task. The paper deals with comparison task, which consisted of interviews and rankings, and provides a discussion of the results of the paper as a whole. Findings - Results of the ranking part of the comparison task confirm the findings of concept mapping task. In both cases, while there are individual differences between mental models, on average they gravitate towards FRBR. Research limitations/implications - This is a small study and it provides only a glimpse of the implications of using FRBR as a conceptual basis for cataloguing. More FRBR-related user studies are needed, including similar studies on different groups of individuals and different types of materials, as well as practical studies of user needs and user interfaces. Practical implications - The results of this study are the first user-tested indication of the validity of FRBR as a conceptual basis for the future of cataloguing. Originality/value - This is the first published paper of mental models of the bibliographic universe and uses a unique combination of mental model elicitation techniques.

Abstract

This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

Abstract

Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.

Abstract

The Functional Requirements for Subject Authority Data (FRSAD) conceptual model defines entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as the subject of a work) and nomen (any sign or arrangement of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question: can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system and Universal Decimal Classification (UDC) are used as a case study to test applicability of the FRSAD model for classification data and the applicability of the Functional Requirements for Bibliographic Records (FRBR) for modelling versions, such as different adaptations and different language editions.

Abstract

Purpose - Despite the importance of bibliographic information systems for discovering and exploring library resources, some of the core functionality that should be provided to support users in their information seeking process is still missing. Investigating these issues, the purpose of this paper is to design a solution that would fulfil the missing objectives. Design/methodology/approach - Building on the concepts of a work family, functional requirements for bibliographic records (FRBR) and information visualization, the paper proposes a model and user interface design that could support a more efficient and user-friendly presentation and navigation in bibliographic information systems. Findings - The proposed design brings together all versions of a work, related works, and other works by and about the author and shows how the model was implemented into a FrbrVis prototype system using hierarchical visualization layout. Research limitations/implications - Although issues related to discovery and exploration apply to various material types, the research first focused on works of fiction and was also limited by the selected sample of records. Practical implications - The model for presenting and interacting with FRBR-based data can serve as a good starting point for future developments and implementations. Originality/value - With FRBR concepts being gradually integrated into cataloguing rules, formats, and various bibliographic services, one of the important questions that has not really been investigated and studied is how the new type of data would be presented to users in a way that would exploit the true potential of the changes.

Abstract

The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.
