Abstract

Climate change as a complex physical and social issue has gained increasing attention in the natural as well as the social sciences. Climate change research has become more interdisciplinary and even transdisciplinary as a typical Mode-2 science that is also dependent on an application context for its further development. We propose to approach interdisciplinarity as a co-construction of the knowledge base in the reference patterns and the programmatic focus in the editorials in the core journal of the climate-change sciences-Climatic Change-during the period 1977-2013. First, we analyze the knowledge base of the journal and map journal-journal relations on the basis of the references in the articles. Second, we follow the development of the programmatic focus by analyzing the semantics in the editorials. We argue that interdisciplinarity is a result of the co-construction between different agendas: The selection of publications into the knowledge base of the journal, and the adjustment of the programmatic focus to the political context in the editorials. Our results show a widening of the knowledge base from referencing the multidisciplinary journals Nature and Science to citing journals from specialist fields. The programmatic focus follows policy-oriented issues and incorporates public metaphors.

Abstract

Today many libraries are using computers and allied information technologies to improve their work methods and services. Consequently, the libraries need such professional staff, or need to train the present one, who could face the challenges placed by the introduction of these technologies in the libraries. To meet the demand of such professional staff, the departments of Library and Information Science in India introduced new courses of studies to expose their students in the use and application of computers and other allied technologies. Some courses introduced are: Computer Application in Libraries; Systems Analysis and Design Technique; Design and Development of Computer-based Library Information Systems; Database Organisation and Design; Library Networking; Use and Application of Communication Technology, and so forth. It is felt that the computer and information technologies biased courses need to be restructured, revised, and more harmoniously blended with the traditional main stream courses of library and information science discipline. We must alter the strategy of teaching library techniques, such as classification, cataloguing, and library procedures, and the techniques of designing computer-based library information systems and services. The use and application of these techniques get interwoven when we shift from a manually operated library system's environment to computer-based library system's environment. As such, it becomes necessary that we must follow an integrative approach, when we teach these techniques to the students of library and information science or train library staff in the use and application of these techniques to design, develop and implement computer-based library information systems and services. In the following sections of this paper, we shall outline the likeness or correspondence between certain concepts and techniques formed by computer specialist and the one developed by the librarians, in their respective domains. We make use of these techniques (i.e. the techniques of both the domains) in the design and implementation of computer-based library information systems and services. As such, it is essential that lessons of study concerning the exposition of these supplementary and complementary techniques must be integrated.

Abstract

The ideal introduction for students of semantics, Lexical Meaning fills the gap left by more general semantics textbooks, providing the teacher and the student with insights into word meaning beyond the traditional overviews of lexical relations. The book explores the relationship between word meanings and syntax and semantics more generally. It provides a balanced overview of the main theoretical approaches, along with a lucid explanation of their relative strengths and weaknesses. After covering the main topics in lexical meaning, such as polysemy and sense relations, the textbook surveys the types of meanings represented by different word classes. It explains abstract concepts in clear language, using a wide range of examples, and includes linguistic puzzles in each chapter to encourage the student to practise using the concepts. 'Adopt-a-Word' exercises give students the chance to research a particular word, building a portfolio of specialist work on a single word.

Abstract

Purpose - The purpose of this paper is to propose the Collaborative Search System that attempts to achieve collaboration by implicitly identifying and reflecting search behaviour of collaborators in an academic network that is automatically and dynamically formed. By using the constructed Collaborative Hit Matrix (CHM), results are obtained that are based on the search behaviour and earned preferences of specialist communities of researchers, which are relevant to the user's need and reduce the time spent on bad links. Design/methodology/approach - By using the Digital Bibliography Library Project (DBLP), the research communities are formed implicitly and dynamically based on the users' research presence in the search environment and in the publication scenario, which is also used to assign users' roles and establish links between the users. The CHM, to store the hit count and hit list of page results for queries, is also constructed and updated after every search session to enhance the collaborative search among the researchers. Findings - The implicit researchers community formation, the assignment and dynamic updating of roles of the researchers based on research, search presence and search behaviour on the web as well as the usage of these roles during Collaborative Web Search have highly improved the relevancy of results. The CHM that holds the collaborative responses provided by the researchers on the search query results to support searching distinguishes this system from others. Thus the proposed system considerably improves the relevancy and reduces the time spent on bad links, thus improving recall and precision. Originality/value - The research findings illustrate the better performance of the system, by connecting researchers working in the same field and allowing them to help each other in a web search environment.

Abstract

Astronomy classification is often overlooked in classification discourse. Its rarity and obscurity, especially within UK librarianship, suggests it is an underdeveloped strand of classification research and is possibly undervalued in modern librarianship. The purpose of this research is to investigate the suitability and practicalities of the discipline of astronomy adopting a subject-specific faceted classification scheme and to provide a provi-sional outline of a special faceted astronomy classification scheme. The research demonstrates that the application of universal schemes for astronomy classification had left the interdisciplinary subject ill catered for and outdated, making accurate classification difficult for specialist astronomy collections. A faceted approach to classification development is supported by two qualitative literature-based research methods: historical research into astronomy classification and an analytico-synthetic classification case study. The subsequent classification development is influenced through a pragmatic and scholarly-scientific approach and constructed by means of instruction from faceted classification guides by Vickery (1960) and Batley (2005), and faceted classification principles from Ranaganathan (1937). This research fills a gap within classification discourse on specialist interdisciplinary subjects, specifically within astronomy and demonstrates the best means for their classification. It provides a means of assessing further the value of faceted classification within astronomy librarianship.

Abstract

The article discusses various aspects of the Dewey Decimal Classification (DDC) system of classifying library books in 2013. Background is presented on some librarians' desire to stop using DDC and adopt a genre-based system of classification. It says librarians can use the DDC to deal with problems and issues related to library book classification. It highlights the benefits of using captions and relative index terms and semantic relationships in DDC.

"As knowledge brokers, we are living in interesting times for libraries and librarians. We wonder sometimes if our traditional tools like the Dewey Decimal Classification (DDC) system can cope with the onslaught of information. The categories provided don't always seem adequate for the knowledge-discovery habits of today's patrons. They have grown accustomed to new ways for their information needs to be met, from the fire-and-forget style of a hard-to-control classic Google search to the pervasive, always-on style of Google Now, anticipating users' information needs without their having even asked a verbal question. Contrariwise, I believe that we, as librarians, could be making better use of our tools. Many (like the DDC) are a reflection of the same social and epistemological forces that brought about modernity at the turn of the last century. We as librarians are in the unique position of providing services that are as ground-breaking as these tools. As we see the need to provide unique and cutting-edge knowledge discovery to our users, I argue in this article that the DDC can play a key role in fulfilling this purpose."

Abstract

This research concerns the frequency of the assignment of author-supplied keyword strings and cataloger supplied subject heading strings within a library catalog. The results reveal that, on average, more author-assigned keywords and more cataloger-assigned Library of Congress Subject Headings were assigned to works emerging from the arts & humanities than to works emerging from the social sciences and science, technology, engineering, and mathematics (STEM) disciplines. STEM disciplines in particular received a lower amount of topical metadata, in part because of the under-assignment of name/title, geographical, and corporate subject headings. These findings reveal how librarians could increase their understanding of how topical access is functioning within academic disciplines.

Abstract

Purpose - Traditional subject indexing and classification are considered infeasible in many digital collections. This paper seeks to investigate ways of enhancing social tagging via knowledge organization systems, with a view to improving the quality of tags for increased information discovery and retrieval performance. Design/methodology/approach - Enhanced tagging interfaces were developed for exemplar online repositories, and trials were undertaken with author and reader groups to evaluate the effectiveness of tagging augmented with control vocabulary for subject indexing of papers in online repositories. Findings - The results showed that using a knowledge organisation system to augment tagging does appear to increase the effectiveness of non-specialist users (that is, without information science training) in subject indexing. Research limitations/implications - While limited by the size and scope of the trials undertaken, these results do point to the usefulness of a mixed approach in supporting the subject indexing of online resources. Originality/value - The value of this work is as a guide to future developments in the practical support for resource indexing in online repositories.

Abstract

There is a long history of music librarianship in the domain of printed Western classical music. Special schemes have been developed to aid in the organization and retrieval of musical works, and existing schemes have been widely used to include these types of documents in larger physical library collections. However, the advent of digital consumer technology in the form of MP3 players and mobile phones, combined with the enormous impact of the internet and the digitization and ease of compression of audio files, has brought new formats and types of user interaction to the fore. This has led to an explosion in music information-retrieval research, concentrating on how most beneficially to use computers to organize, search and retrieve music information and recordings from large digital collections. Many of us today carry around music collections of thousands of digitized music recordings and access all manner of types of music on the web, but still are unsure what to listen to next: the enormous size of these collections and the instant accessibility of 8 million Western pop, classical, jazz and folk songs can cause confusion and trepidation. Where the classical music researcher would previously have consulted academic texts and visited a specialist music library, or the post-rock listener would have read the New Musical Express and visited the Rough Trade shop for advice on what was coming up, now we access music through hand-held devices and laptops. The issue is no longer 'I hope I can find that Velvet Underground live album somewhere this year, I wonder what it sounds like', but 'Which Velvet Underground live track shall I read about/ download/ stream now?

Abstract

This is a publisher ranking study based on a citation data grant from Elsevier, specifically, book titles cited in Scopus history journals (2007-2011) and matching metadata from WorldCat® (i.e., OCLC numbers, ISBN codes, publisher records, and library holding counts). Using both resources, we have created a unique relational database designed to compare citation counts to books with international library holdings or libcitations for scholarly book publishers. First, we construct a ranking of the top 500 publishers and explore descriptive statistics at the level of publisher type (university, commercial, other) and country of origin. We then identify the top 50 university presses and commercial houses based on total citations and mean citations per book (CPB). In a third analysis, we present a map of directed citation links between journals and book publishers. American and British presses/publishing houses tend to dominate the work of library collection managers and citing scholars; however, a number of specialist publishers from Europe are included. Distinct clusters from the directed citation map indicate a certain degree of regionalism and subject specialization, where some journals produced in languages other than English tend to cite books published by the same parent press. Bibliometric rankings convey only a small part of how the actual structure of the publishing field has evolved; hence, challenges lie ahead for developers of new citation indices for books and bibliometricians interested in measuring book and publisher impacts.

Abstract

Historical development has led to the decay of natural philosophy, which until the nineteenth century included all of our knowledge about the physical world, in the growing multitude of specialized sciences, within the 'Classical Model of Science'. The focus on the in-depth enquiry disentangled from its broad context led to the problem of the loss of a common world view and the impossibility of communication between specialist research fields because of different languages that they developed in isolation. The need for a new unifying framework is becoming increasingly apparent, with information technology enabling and intensifying the communication between different research fields, knowledge communities and information sources. This time, not only natural sciences, but also all of human knowledge is being integrated through a global network such as the internet with its diverse knowledge and language communities. Info-computationalism (ICON) as a synthesis of pancomputationalism and paninformationalism presents a unifying framework for the understanding of natural phenomena including living beings and their cognition, their ways of processing information and producing knowledge. Within ICON, the physical universe is understood as a network of computational processes on an informational structure. The matter/energy in this model is replaced by information/ computation where information is the structure, whose dynamics are identified as natural computation. ICON is an example of a philosophical framework in a direct connection with the related scientific fields, and the process is one of mutual exchange: scientific findings influence philosophical thinking, and vice versa.

Abstract

Analyzing large quantities of real-world textual data has the potential to provide new insights for researchers. However, such data present challenges for both human and computational methods, requiring a diverse range of specialist skills, often shared across a number of individuals. In this paper we use the analysis of a real-world data set as our case study, and use this exploration as a demonstration of our "insight workflow," which we present for use and adaptation by other researchers. The data we use are impact case study documents collected as part of the UK Research Excellence Framework (REF), consisting of 6,679 documents and 6.25 million words; the analysis was commissioned by the Higher Education Funding Council for England (published as report HEFCE 2015). In our exploration and analysis we used a variety of techniques, ranging from keyword in context and frequency information to more sophisticated methods (topic modeling), with these automated techniques providing an empirical point of entry for in-depth and intensive human analysis. We present the 60 topics to demonstrate the output of our methods, and illustrate how the variety of analysis techniques can be combined to provide insights. We note potential limitations and propose future work.

Abstract

Purpose Information seeking is often performed in collaborative contexts. The research into such collaborative information seeking (CIS) has been proceeding since the 1990s but lacks methodological discussions. The purpose of this paper is to analyze and discuss methodological issues in existing CIS studies. Design/methodology/approach The authors systematically review 69 empirical CIS studies. Findings The review shows that the most common methods of data collection are lab experiments (43 percent), observation (19 percent) and surveys (16 percent), that the most common methods of data analysis are description (33 percent), statistical testing (29 percent) and content analysis (19 percent) and that CIS studies involve a fairly even mix of novice, intermediate and specialist participants. However, the authors also find that CIS research is dominated by exploratory studies, leaves it largely unexplored in what ways the findings of a study may be specific to the particular study setting, appears to assign primacy to precision at the expense of generalizability, struggles with investigating how CIS activities extend over time and provides data about behavior to a larger extent than about reasons, experiences and especially outcomes. Research limitations/implications The major implication of this review is its identification of the need for a shared model to which individual CIS studies can contribute in a cumulative manner. To support the development of such a model, the authors discuss a model of the core CIS process and a model of the factors that trigger CIS. Originality/value This study assesses the current state of CIS research, provides guidance for future CIS studies and aims to inspire further methodological discussion.

Abstract

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains.

Abstract

The conflict between librarians' ethics and their responsibilities in the process of progressive collection management, which applies the principles of cost accounting to libraries, to call attention to the "bad books" in their collections that are compromised by age, error, abridgement, expurgation, plagiarism, copyright violation, libel, or fraud, is discussed. According to Charles Cutter, notes in catalog records should call attention to the best books but ignore the bad ones. Libraries that can afford to keep their "bad books," however, which often have a valuable second life, must call attention to their intellectual contexts in notes in the catalog records. Michael Bellesiles's Arming America, the most famous case of academic fraud at the turn of the twenty-first century, is used as a test case. Given the bias of content enhancement that automatically pulls content from the Web into library catalogs, catalog notes for "bad books" may be the only way for librarians to uphold their ethical principles regarding collection management while fulfilling their professional responsibilities to their users in calling attention to their "bad books."

Abstract

This paper is about search of photos in photo databases of agencies which sell photos over the Internet. The problem is far from the behavior of photo databases managed by librarians and also far from the corpora generally used for research purposes. The descriptions use mainly single words and it is well known that it is not the best way to have a good search. This increases the problem of semantic ambiguity. This problem of semantic ambiguity is crucial for cross-language querying. On the other hand, users are not aware of documentation techniques and use generally very simple queries but want to get precise answers. This paper gives the experience gained in a 3 year use (2006-2008) of a cross-language access to several of the main international commercial photo databases. The languages used were French, English, and German.
