Structural and semantic interoperability have been the focus of digital library research in the early 1990s. Many research works have been done on searching and retrieving objects across variations in protocols, formats, and disciplines. As the World Wide Web has become more popular in the last ten years, information is available in multiple languages in global digital libraries. Users are searching across the language boundary to identify the relevant information that may not be available in their own language. Cross-lingual semantic interoperability has become one of the focuses in digital library research in the late 1990s. In particular, research in cross-lingual information retrieval (CLIR) has been very active in recent conferences on information retrieval, digital libraries, knowledge management, and information systems. The major problem in CLIR is how to build the bridge between the representations of user queries and documents if they are of different languages.

This chapter examines the techniques behind a user interface that computes a multi-document summary of documents retrieved by a search. As a user’s query can retrieve thousands of relevant documents, it is paramount that they be logically organized. In digital libraries, documents are traditionally represented as a ranked list of documents ordered by computed relevance and do not take into account presentation techniques used by information professionals (such as librarians) in the physical library. This chapter examines a framework used in a consumer healthcare digital library that incorporates techniques used by librarians. It brings together commonalities between documents and highlights their salient differences to target the needs of users using the browsing and searching modes of information seeking. It achieves this by discovering common and unique topics among its input from a combination of structural and lexical cues.

This chapter introduces a new category of digital library user interfaces called metadata-enhanced visual interfaces. Drawing on the earlier information retrieval visual interfaces that have made use of thesauri, this chapter will review and analyze metadata-enhanced visual interfaces to digital libraries based on two key variables, namely metadata elements used for visualization purposes and visual metaphors incorporated into the user interfaces. The aim of this study is to inform the design of visual interfaces for digital libraries through bringing together issues that have roots in such communities as information retrieval, digital libraries, human-computer interaction, and metadata. The findings of this study provide design ideas and implications for digital library interface design in terms of the various metadata-based information search and retrieval features for visualization purposes.

This chapter addresses the question of how the analysis of results retrieved from online bibliographic information systems changed over the last 32 years as digital libraries have evolved. It demonstrates that Digital Libraries of the future will enable knowledge discovery by providing direct access to the semantic content of documents through the implementation of text mining tools. To achieve this research with IR systems and text-mining tools, pipeline pilot (Bandy, et al., 2009), I2E (Vellay, 2009), and BioText will need to be conducted by experts in information retrieval not just subject scientific specialists.

<p>The purpose of this paper is to report the findings of a systematic literature review carried out to investigate the applications and potential roles of thesaurus in digital libraries. It also describes the process of systematic literature review (SLR) followed to carry out this study. 321 unique publications from Library and Information Science Abstracts (LISA) and Scopus had been subjected to SLR, and 29 papers have been analysed. Various possible applications of thesaurus in digital libraries have been identified and described. Also different approaches followed by researchers in choice of the thesaurus have been identified. Search and browse functionalities offered by thesaurus to the users of digital libraries are described. The discussion presented in this paper can play as cues for the digital library administrators in decision making towards implementing thesaurus for enhanced information retrieval. This study would allow researchers of information retrieval systems, including that of digital libraries, to proceed from more informed standpoints. Also, the discussion can be used to evaluate and improve education in library and information science.</p>

Purpose – The purpose of this paper is to explore children’s spatial cognitive abilities as they engaged in information-seeking behaviors on two-dimensional (2D) and three-dimensional (3D) digital interfaces. Design/methodology/approach – Children between the ages of seven and 11 were observed as they browsed either a 2D or 3D navigation interface for a children’s digital library. Data regarding their use of the overview function and depth cues were analyzed to reveal the relationships between search performance efficiency, precision, and effectiveness and the associative memory, visualization memory, and spatial visualization abilities of the user. Findings – Children spent less time using the 2D interface when compared to time spent using the 3D interface. Children exhibited better performance precision when using the 3D interface. Children applied exhaustive strategies and more varied cognitive skills across different tasks when using the 2D interface, and applied a more focussed approach when using the 3D interface. Originality/value – The cognitive abilities of children are not yet fully developed, so they require a unique user interface when browsing digital libraries. This study served the practical purpose of developing a game-like user interface for ease of use. Providing an effective overview function allows young users with less developed cognitive abilities to navigate informational cues. They can then build an effective mind map and implement efficient way-finding strategies.

BACKGROUND Background: The unified medical language system (UMLS) has been a critical tool in biomedical and health informatics, and the year 2020 marks the 30th anniversary of UMLS. Despite its longevity, there is no systematic review on UMLS, in general. Thus, this systematic review was conducted to provide an overview of UMLS and its usage in English-language publications in the last 30 years. OBJECTIVE Objectives: The objective is twofold: to provide a comprehensive and systematic picture of the themes, their subtopics, and the publications under each category and to document systematic evidence of UMLS and how it has been used in English-language publications in the last 30 years. METHODS Methods: PubMed, ACM Digital Library, and Nursing & Allied Health Database were used to search for literature. The primary literature search strategy was as follows: UMLS was used as a MeSH term or a keyword or appeared in the title or abstract. Only English-language publications were considered. RESULTS Results: A total of 943 publications were included in the final analysis. After analysis and categorization of publications, UMLS was found to be used in the following emerging themes: natural language processing (NLP) (230 publications), information retrieval (125 publications), terminology study (90 publications), ontology and modeling (80 publications), medical subdomains (76 publications), other language studies (53 publications), artificial intelligence tools and applications (46 publications), patient care (35 publications), data mining and knowledge discovery (25 publications), medical education (20 publications), degree-related theses (13 publications), and digital library (5 publications) as well as UMLS itself (150 publications). CONCLUSIONS Conclusions: UMLS has been used and published successfully in patient care, medical education, digital libraries, and software development, as originally planned, as well as in degree-related theses, building artificial intelligence tools, data mining and knowledge discovery and more foundational work in methodology and middle layers that may lead to advanced products. NLP, UMLS itself, and information retrieval are the three themes with the most publications. The review provides systematic evidence of UMLS in English-language peer-reviewed publications in the last 30 years.

Digital libraries evolved in response to the need to manage the vast quantities of electronic information that we produce, collect, and consume. Architects of such systems have adopted a variety of design approaches, which are summarized and illustrated in this chapter. We also introduce the following three chapters, and provide suitable background. From a historical perspective, we note that early systems were designed independently to afford services to specific communities. Since then, systems that store and mediate access to information have become commonplace and are scattered all over the Internet. Consequently, information retrieval also has to contend with distributed/networked systems in a transparent and scalable fashion. In this context, digital library architects have adopted various interoperability standards and practices to provide users with seamless access to highly distributed information sources. This chapter looks at current research and emerging best practices adopted in designing digital libraries, whether individual or distributed.

Today's digital library is a necessity. A system that provides all-digital information and services requires that all aspects of it should be accessed effectively. In the context of information retrieval in digital libraries, the information retrieval systems are important instruments. The system becomes a link between relevant information and its users. Evaluation of the information retrieval system to determine its effectiveness is important to ensure that users receive good retrieval services. Recall and precision are approaches to measure the effectiveness of information retrieval systems that are widely used. This study aims to determine the effectiveness of the ISI Yogyakarta digital library retrieval system based on recall and precision approaches. This study will provide benefits for librarians in knowing the effectiveness of the information retrieval system and the extent of their accuracy in indexing. This research uses an experimental method with a quantitative approach. The researcher chose a sample of the searching keywords purposively and then tested them by searching on the portal http://digilib.isi.ac.id/. The data obtained were analyzed using the formula recall and precision. In this study the subjects tested were interior design subjects. The precision measurement of 10 keywords on the subject of interior design gets 92.37% results while the recall measurement gets 80.79% results. The result stated that precision is higher than recall, it showed that the information retrieval system of ISI Yogyakarta’s digital library is quite effective.
