Exploring user experience in digital libraries through questionnaire and eye-tracking data

In the field of digital libraries, research on user experience is sparse, especially in terms of emotions, impressions, and stimulation evoked by interaction with the digital library. Given the many different methods and tools available for assessing user experience, two questionnaires and eye-tracking were explored to see how each can contribute to understanding user experience in digital libraries. An eye-tracking study with 30 participants was carried out using two digital libraries. Analysis of the questionnaires revealed that overall, one digital library was experienced more positively, with the difference most evident in the hedonic quality. The eye-tracking data revealed different gaze patterns in the two digital libraries, with significant difference in measure values particularly on the search boxes. When eye-tracking was combined with the questionnaire data, several correlations were found, indicating that the search box position and the intuitiveness of the homepage had an impact on the user experience.

Metadata, Digital Museum Spaces and Accessibility for Persons with Impairments

This study examines the intersection of metadata and accessibility in the digital museum space. While virtual museums can remove physical barriers to heritage institutions, virtual spaces still have barriers for certain impairments. Work done in the field of digital libraries has shown that accessibility metadata can help to remove some of those barriers. This exploratory research project aims to provide understanding of the ways that metadata in virtual museum spaces is being used and how that metadata can improve accessibility in these spaces. How can universal design be best applied to metadata in digital museum catalogs and objects? What kinds of metadata in digital museum collections can potentially increase accessibility? Are museums currently including metadata that increases accessibility for people with disabilities and impairments? These questions were explored using a content-analysis approach applied to textual information collected from forty objects in four digital collections found on the publicly accessible webpages of Canadian institutions of cultural heritage.

Configurational Path to Chinese Reading Stickiness of Digital Library

Attracting and retaining readers in an increasingly competitive environment is an urgent problem for digital libraries of original literature. However, few empirical studies address online reading stickiness, particularly the factors affecting the promotion of online reading stickiness, in what combinations or paths these effects exist, and whether there are complementary, alternative, and inhibitory relationships among the factors. To solve the practical problems and fill the theoretical gap, we use a fuzzy-set qualitative comparative analysis to study the interaction effects of the flow experience (feeling of immersion and perceived pleasure), technology acceptance model (perceived usefulness and perceived ease of use), and customer participation (information sharing and interpersonal interaction) to identify the critical configurations leading to a high level of stickiness in online reading and to verify the complementarity, substitution, and inhibition relationships among these variables. The findings provide implications for further research on complexity theory in digital libraries of original literature, and for managers to view and redesign online reading stickiness as configurations of IT and psychological capabilities. This study enriches and develops the existing theories and expands the application of the qualitative comparative analysis method in the field of digital libraries.

Research Collaboration and Authorship Pattern in the field of Semantic Digital Libraries

This study aims to explore research collaborations and authorship patterns in the field of semantic digital libraries(SDL). The data is extracted (N=2075) from the Scopus database using keywords related to semantic digital libraries by considering all types of publications during 1983-2019. The analysis of each document is based on the following scientometrics indicators: author productivity, degree of collaboration, collaboration index, collaboration coefficient and modified collaboration coefficient. Correlation matrices were also calculated and inferences drawn in terms of authors and publications. A network visualisation tool VOSviewer was used to present authorship correlation network strength and keyword mapping for a better insight into the emerging areas in the field of SDL. The resulting average degree of collaboration of 0.898 indicates that a large number of publications are multi-authored and that there is a higher level of collaborative research in the field of semantic digital libraries. Meghini C from the Institute of Information Science and Technologies, Italy has produced the highest number of research paper(n=18) whereas Egenhofer MJ found to be a profoundly impacted author with 851 citations on in the studied domain. Results also reveal that the focus areas of research related to SDL include digital libraries, semantic web, ontology, metadata and information retrieval. However, keywords such as natural language processing system, computational linguistics, linked data are also repeated frequently in the published literature, thus revealing the emerging areas of the future research in the domain of SDL.

Use of Open Access Publishing by Researchers an Analysis of Open Access Availability of Research Literature in the field of Digital Library


 
 
 This paper aims to examine the availability of Open Access (OA) research literature in the field of digital library. In order to analyse the availability of OA research literature in the field of digital library, a search was conducted on Web of Science’s Core collection database on June 11, 2019. In response to a topic search TS = “Digital Library” using the advanced search option, 849 articles were retrieved. Of the 849 articles examined, the details of 26 articles were not found in the Google Scholar. Therefore, 823 articles were selected for further analyses. After examining the Websites of OA articles, they were classified into three categories: gold OA, green OA, and both gold and green OA. Furthermore, all the green OA articles were systematically organised into six groups for the examination of the self-archiving venues used by the researchers for self-archiving. Out of 823 articles analysed, OA versions were found for 64.76 per cent of articles. This study found that 26.68 per cent of OA articles were available through gold OA and 60.39 per cent articles were available through green OA, while 36.53 per cent articles were accessible via both OA journals and self-archiving (gold & green OA). Although researchers used various OA platforms for self-archiving of their research work, publishers’ Websites were found as the most preferred choice for self-archiving of research work by the authors in the field of digital library. Computer Science discipline has the highest share of OA copies available through self-archiving. However, it is important to point out that more than 78 per cent of self-archived articles were found as the final publisher’s PDF versions of the article which publishers never allow for self-archiving.
 
 

MODERNIZATION IN THE ACADEMIC LIBRARIES

In the present paper, a researcher will discuss the Academic Libraries in the Digital Era and Best practices for modernizing the library. As we know that, the field of digital libraries brings together participants from many existing areas of research. Currently, the domain lacks a clear agenda Academic Libraries in the digital age of this other area. It is tempting for researchers to think that the field of digital modernizing libraries is a natural outgrowth of an already known field, from a database Development of Academic Libraries or Digital Libraries information, can be present realised as a form of joined records. Since a viewpoint, the field of A Modern Academic Library could appear to be a use of the Academic libraries in the digital era. From a library science perspective, Digital Technologies might be seen as continuing a trend toward library Digitization.

Digital liaisons: Connecting diverse voices to support an ethical and sustainable information future in digital libraries

ABSTRACTDigital Liaisons is a platform for including student and early career voices in open dialogue with practitioners and researchers who work in or adjacent to the field of Digital Libraries. It has taken several forms over the last few years, ranging from a poster session, to an unconference‐style panel, to moderated Twitter chats. This year we are proposing to merge two of these approaches: a series of Twitter chats that provide mentor‐mentee connections for early career practitioners, and a panel which reports on the outcomes of these chats and concludes with a digital poster session for students and early‐career practitioners. The merger of Twitter chats and a digital poster session will provide two ways for participants to interact with the theme of this year's conference and will allow sharing their views and experiences.

Trends and challenges of visual search interfaces in digital libraries and repositories

PurposeThis paper aims to present an overview of the challenges encountered in integrating visual search interfaces into digital libraries and repositories. These challenges come in various forms, including information visualisation, the use of knowledge organisation systems and metadata quality. The main purpose of this study is the identification of criteria for the evaluation and integration of visual search interfaces, proposing guidelines and recommendations to improve information retrieval tasks with emphasis on the education-al context.Design/methodology/approachThe information included in this study was collected based on a systematic literature review approach. The main information sources were explored in several digital libraries, including Science Direct, Scopus, ACM and IEEE, and include journal articles, conference proceedings, books, European project reports and deliverables and PhD theses published in an electronic format. A total of 142 studies comprised the review.FindingsThere are several issues that authors did not fully discuss in this literature review study; more specific, aspects associated with access of digital resources in digital libraries and repositories based on human computer interaction, i.e. usability and learnability of user interfaces; design of a suitable navigation method of search based on simple knowledge organisation schemes; and the use of usefulness of visual search interfaces to locate relevant resources.Research limitations/implicationsThe main steps for carrying out a systematic review are drawn from health care; this methodology is not commonly used in fields such as digital libraries and repositories. The authors aimed to apply the fundamentals of the systematic literature review methodology considering the context of this study. Additionally, there are several aspects of accessibility that were not considered in the study, such as accessibility to content for disabled people as defined by ISO/IEC 40500:2012.Originality/valueNo other systematic literature reviews have been conducted in this field. The research presents an in-depth analysis of the criteria associated with searching and navigation methods based on the systematic literature review approach. The analysis is relevant for researchers in the field of digital library and repository creation in that it may direct them to considerations in designing and implementing visual search interfaces based on the use of information visualisation.

Factors influencing the intention to use information service mashups

Purpose This study aims to examine the factors influencing the adoption intention of information service mashup in digital library (DL). The study is an empirical study on DLs in China. Design/methodology/approach This paper employs the theory of information service mashup as its theoretical background and applies it to the field of DL to develop the measurement model which is based on technology acceptance model (TAM). A structured questionnaire was developed including the demographic information, the advantages of information service mashup in DL and the Likert evaluation of each construct. As a result, of 303 questionnaires distributed among DL users, 281 were remained as acceptable answers. The data were processed and analyzed with the aid of the SPSS 20.0 and SmartPLS 2.0. Findings The results show that beyond perceived usefulness and perceived ease of use, both perceived integration and perceived risk have direct impacts on user’s intention to adopt information service mashup in DL. Perceived integration has the dramatic positive effects, while perceived risk negatively correlates to adoption intention. Moreover, perceived integration and individualization have positive impacts on perceived ease of use, while network externality positively influences perceived usefulness. Originality/value Information service mashup is still a relatively new technology in DL. There were few theoretical and empirical studies that examine the user adoption behaviour of the service. This study contributes to existing information service mashup application studies by modifying and extending TAM. The results would help the DL gain a deeper understanding of the factors affecting DL user adoption of information service mashup.

Exploring the topic hierarchy of digital library research in China using keyword networks: a K-core decomposition approach

Exploring the topic hierarchy of a research field can help us better recognize its intellectual structure. This paper proposes a new method to automatically discover the topic hierarchy, in which the keyword network is constructed to represent topics and their relations, and then decomposed hierarchically into shells using the K-core decomposition method. Adjacent shells with similar morphology are merged into layers according to their density and clustering coefficient. In the keyword network of the digital library field in China, we discover four different layers. The basic layer contains 17 tightly-interconnected core concepts which form the knowledge base of the field. The middle layer contains 13 mediator concepts which are directly connected to technology concepts in the basic layer, showing the knowledge evolution of the field. The detail layer contains 65 concrete concepts which can be grouped into 13 clusters, indicating the research specializations of the field. The marginal layer contains peripheral or isolated concepts.

A study to evaluate the digitization level of Korean libraries (part I)

Purpose – The purpose of this paper is to discover and enumerate the elements of the digital library and measure how much an individual library was equipped with the characteristics of the digital library accordingly. Design/methodology/approach – For this purpose several steps were taken. First, research on the characteristics and the representative services of the digital library were comprehensively reviewed. Second, examples of the library services that were being considered for the next generation digital library were investigated to compare with the conventional library services. Third, the elements of the conventional and the digital libraries initially extracted were examined by ten experts. These experts were composed of researchers and professors specializing in digital libraries, and career librarians who had worked in the digital library field for at least ten years. The elements were verified through discussions with them. Fourth, 19 university libraries, 16 public libraries, and 17 special libraries were selected in accordance with the verified elements of the conventional and the digital libraries to measure the digitization level of the libraries. Findings – The following is a summary of the evaluation of the first eight evaluation items, which are covered in Part 1 of this study. The remaining five items will be covered in Part 2. First, the digitization level of the acquisition element and classification and cataloguing was significantly high. Second, book collections excluding “digital video,” reference service, library program service, and space service showed significantly conventional characteristics. Third, in the element of circulation services, the item of lending books offline and returning the books scored 92.64 and the item of lending-returning with use of smart devices and social media obtained significantly low scores. Also, the average in using the book return desk for the circulation service was 81.39, much higher than using the automatic book return machine, which scored 18.61, by a wide margin. Fourth, in the element of user services, the digital item of providing support for mobile services related to the library resources demonstrated higher scores than the conventional item, but other items showed more conventional characteristics. In particular, the item of duplication services for material scored 94.99, but other items such as support for publication/bookbinding services using digital publication tools and devices obtained significantly low scores. Originality/value – This study is first study in the world to measure the level of digitization of the library. Therefore, hereafter, each library will be able to measure and determine its digital position based on these elements. Up to now, some research was performed in pursuit of extracting the elements of a library but it has relied solely on literature review. Comprehensive research had never been performed as in this study.

The Research on Personalized Recommendation Algorithm of Library Based on Big Data and Association Rules

In order to provide better information consistent with their preferences features for users, personalized recom- mendation technology has become an important research field of digital libraries and get more and more attention from searchers. Among them, the large data mining and association rules-based personalized recommendation technology is the focus of research in the field of recommendation. In this paper, these two issues are studied. In order to increase the lend- ing rate of collections, this paper use association rules analyzes for borrowing pattern mining, to obtain library users inter- ests, to analyze different types of readers' purpose library collections, and automatically provide readers with other books related to such book. Through improved frequent pattern growth algorithm, combined with online recommended and off- line recommendation method, achieved a more satisfactory recommendation results. Finally, taken experimental analysis and verification for these techniques studies, and future research were discussed.

Using Document Store for 3D Virtual Collections

This paper describes the latest improvements to a recently developed online environment for managing virtual collections of 3D objects. As part of that effort we introduced a document-oriented NoSQL layer for storing the data describing the 3D objects and collections, provided by the MongoDB engine. This technology has many advantages for describing the type of data and metadata used in our application, which are also valid for and can be applied to the field of digital libraries in general.

Convergence of digital humanities and digital libraries

Purpose – Digital humanities (DH) has become a much discussed topic among both humanities scholars and library professionals. The library and information science (LIS) community has taken efforts in providing new facilities and developing new services to meet humanities scholars’ changing research behaviors and needs employing digital tools and methods. How to effectively collaborate with the DH community has been a challenging task to LIS in their digital library (DL) development endeavors. The purpose of this paper is to discover productive ways for LIS to support DH scholarship, specifically, what DL components, including content, technology, and service, should and could be developed for digital humanists. Design/methodology/approach – As an initial effort of the Digital Humanities Interest Group at University of California, Irvine Libraries, the examination is primarily based on a cross-boundary environmental scan in both DH and DL fields. The environmental survey includes both a literature review and web and physical site visits. The survey results, especially a gap analysis between the behaviors and needs of humanities scholars and the digital content, technologies, and services currently offered by the DL community, are used to shape the proposed roles of DH librarianship. Findings – First, DH’s innovative approach to research and teaching practices brings opportunities and challenges. Second, DH research is collaborative work. Third, major channels are established for the DH community. Fourth, various tools and data sets are developed to support different types of projects. Fifth, DH community has unbalanced geographical and disciplinary distribution. Sixth, DH research output still lacks attention, integration, and sustainability. Finally, LIS professionals play unique roles in DH projects. Overall, the communities of DH and DL share common goals and tasks. Practical implications – This paper proposes these present and future roles of LIS professionals: creator and contributor; curator; messenger and liaison; educator; mediator and interpreter; host; partner; innovator; “hybrid scholar”; advocate; consultant. At the organizational level, libraries should demonstrate higher efficiency and effectiveness in the services by revamping organizational culture or structure to stimulate and realize more and deeper cross-boundary conversations and collaborations. On a larger scale, the DL community should strive to become more visible, valuable, and approachable to the DH community; and even better, become part of it. Originality/value – This paper examines both DH and DL fields critically and connects the two communities by discovering gaps and commonalities. Based on the findings, the authors recommend roles and actions to be taken by LIS professionals, libraries, and the DL community. This paper is valuable to both humanities scholars who are seeking support in their research using digital methods and LIS professionals who are interested in providing more effective and suitable services. The paper also helps library administrators and aspiring librarians better understand the concept of DH and grasp insight on the present and future of DH librarianship.

Efficient relation extraction method based on spatial feature using ELM

Entity relation extraction can be applied in the automatic question answering system, digital library and many other fields. However, the previous works on this topic mainly focused on the features from a sentence itself in the data sets, without considering the links between sentences in the corpus. In this paper, we propose a concept model and obtain a new effective spatial feature based on this concept model. The added feature makes our feature space concerning not only the inherent information of the sentence itself, but also the semantic information connection between sentences. At last, we use ELM as the training classifier in entity relation extraction. The experiment result shows that the precision and recall of the relation extraction both have a significant increase, by using the new feature. Also, the use of ELM significantly reduces the time of relation extraction. It has a better performance than the traditional method based on SVM.

ELDORADO Project

Hungarian libraries have formed a consortium that led by the National Széchényi Library (NSZL). This consortium is maintaining a project called ELDORADO that provides a new service model and infrastructure environment in digital library field. Our company Cultware is the main system developer partner, focusing on the building of the whole hardware and software architecture and infrastructure of the project. The main scope of the project can be set by some major objectives: Providing digital access for library holdings regardless of their copyright or digitization status. It occurs a large set of on-demand digitisation activities, the registration of digital documents that have digitized already in different libraries in a common single service environment. These activities have coordinated by a library consortium in partnership with all the relevant stakeholders on the related fields. Offering equal and remote access to digital information to all Hungarian spoken people regardless their geographical location is an ultimate goal of the project. Digital access must include a large set of copyrighted materials, orphan works and public domain documents. A major goal (through new collaboration forms with publishers) is to re-publish out-of commerce works in digital format. The project includes collection, preservation and publication activities together in a single service environment.

Semantic ontologies for multimedia indexing (SOMI)

Purpose– The overwhelming speed and scale of digital media production greatly outpace conventional indexing methods by humans. The management of Big Data for e-library speech resources requires an automated metadata solution. The paper aims to discuss these issues.Design/methodology/approach– A conceptual model called semantic ontologies for multimedia indexing (SOMI) allows for assembly of the speech objects, encapsulation of semantic associations between phonic units and the definition of indexing techniques designed to invoke and maximize the semantic ontologies for indexing. A literature review and architectural overview are followed by evaluation techniques and a conclusion.Findings– This approach is only possible because of recent innovations in automated speech recognition. The introduction of semantic keyword spotting allows for indexing models that disambiguate and prioritize meaning using probability algorithms within a word confusion network. By the use of AI error-training procedures, optimization is sought for each index item.Research limitations/implications– Validation and implementation of this approach within the field of digital libraries still remain under development, but rapid developments in technology and research show rich conceptual promise for automated speech indexing.Practical implications– The SOMI process has been preliminarily tested, showing that hybrid semantic-ontological approaches produce better accuracy than semantic automation alone.Social implications– Even as testing proceeds on recorded conference talks at the University of Tebessa (Algeria), other digital archives can look toward similar indexing. This will mean greater access to sound file metadata.Originality/value– Huge masses of spoken data, unmanageable for a human indexer, can prospectively find semantically sorted and prioritized indexing – not transcription, but generated metadata – automatically, quickly and accurately.
