    Abstract
    Information science (IS) is concerned with the searching and retrieval of text and other information (IR), mostly in electronic databases and on the Internet. Such databases contain fulltext (or other kinds of documents, e.g. pictures) and/or document representations and/or different kinds of 'value added information'. The core theoretical problems for IS is related to the determination of the usefulness of different 'subject access points' in electronic databases. This problem is again related to theories of meaning and semantics. This paper outlines some important principles in the design of documents done in the field of 'composition studies'. It maps the possible subject access points and presents research done on each kind of these. It shows how theorie of IR must build on or relate to different theories of concepts and meaning. It discusses 2 contrasting theories of semantics worked out by Ludwig Wittgenstein: 'the picture theory' and 'the theory od language games' and demonstrates the different consequences for such theories for IR. Finally, the implications for information professionals are discussed

    Abstract
    This paper considers classical bibliographic databases based on the Boolean retrieval model (for example MEDLINE and PsycInfo). This model is challenged by modern search engines and information retrieval (IR) researchers, who often consider Boolean retrieval as a less efficient approach. This speech examines this claim and argues for the continued value of Boolean systems, which implies two further issues: (1) the important role of human expertise in searching (expert searchers and "information literacy") and (2) the role of knowledge organization (KO) in the design and use of classical databases, including controlled vocabularies and human indexing. An underlying issue is the kind of retrieval system for which one should aim. It is suggested that Julian Warner's (2010) differentiation between the computer science traditions, aiming at automatically transforming queries into (ranked) sets of relevant documents, and an older library-orientated tradition aiming at increasing the "selection power" of users seems important. The Boolean retrieval model is important in order to provide users with the power to make informed searches and have full control over what is found and what is not found. These issues may also have important implications for the maintenance of information science and KO as research fields as well as for the information profession as a profession in its own right.

    Abstract
    Report on the conference on Information Authority and user knowledge held in Boras Apr 93 and arranged by Gothenburg University's Centre for Library and Information Science and Studies and Boras Library High School. The main speaker, Patrick Wilson, spoke on consequences of information overload and rapid conceptual change. Johan Olaisen's talk on 'toward a theory of clarified subjectivity' started like Wilson's with the problem that users of information systems drown in trivialities. Lena Olsson's dealt with library work in practice and commented on the connection between cognitive authority and professional status of librarians. Discussions centered on the definition of information authority, and on overload as the driving force in IF development

    "This letter considers some main arguments in Professor Bates' article (2008), which is part of our former debate (Bates, 2005,2006; Hjoerland, 2007). Bates (2008) does not write much to restate or enlarge on her theoretical position but is mostly arguing about what she claims Hjorland (2007) ignored or misinterpreted in her two articles. Bates (2008, p. 842) wrote that my arguments did not reflect "a standard of coherence, consistency, and logic that is expected of an argument presented in a scientific journal." My argumentation below will refute this statement. This controversy is whether information should be understood as a subjective phenomenon (alone), as an objective phenomenon (alone), or as a combined objective and a subjective phenomenon ("having it both ways"). Bates (2006) defined "information" (sometimes, e.g., termed "information 1," p. 1042) as an objective phenomenon and "information 2" as a subjective phenomenon. However, sometimes the term "information" is also used as a synonym for "information 2," e.g., "the term information is understood to refer to one or both senses" (p. 1042). Thus, Professor Bates is not consistent in using the terminology that she herself introduces, and confusion in this controversy may be caused by Professor Bates' ambiguity in her use of the term "information." Bates (2006, p. 1033) defined information as an objective phenomenon by joining a definition by Edwin Parker: "Information is the pattern of organization of matter and energy." The argument in Hjoerland (2007) is, by contrast, that information should be understood as a subjective phenomenon all the way down: That neither the objective definition of information nor "having it both ways" is fruitful. This is expressed, for example, by joining Karpatschof's (2000) definition of information as a physical signal relative to a certain release mechanism, which implies that information is not something objective that can be understood independently of an observer or independently of other kinds of mechanism that are programmed to be sensitive to specific attributes of a signal: There are many differences in the world, and each of them is potentially informative in given situations. Regarding Parker's definition, "patterns of organization of matter and energy" are no more than that until they inform somebody about something. When they inform somebody about something, they may be considered information. The following quote is part of the argumentation in Bates (2008): "He contrasts my definition of information as 'observer-independent' with his position that information is 'situational' and adds a list of respected names on the situational side (Hjoerland, 2007, p. 1448). What this sentence, and much of the remainder of his argument, ignores is the fact that my approach accounts for both an observer-independent and a contextual, situational sense of information." Yes, it is correct that I mostly concentrated on refuting Bates' objective definition of information. It is as if Bates expects an overall appraisal of her work rather than providing a specific analysis of the points on which there are disagreements. I see Bates' "having it both ways": a symptom of inconsistence in argumentation.
    Bates (2008, p. 843) further writes about her definition of information: "This is the objectivist foundation, the rock bottom minimum of the meaning of information; it informs both articles throughout." This is exactly the focus of my disagreement. If we take a word in a language, it is understood as both being a "pattern of organization of matter and energy" (e.g., a sound) and carrying meaning. But the relation between the physical sign and its meaning is considered an arbitrary relation in linguistics. Any physical material has the potential of carrying any meaning and to inform somebody. The physical stuff in itself is not information until it is used as a sign. An important issue in this debate is whether Bates' examples demonstrate the usefulness of her own position as opposed to mine. Her example about information seeking concerning navigation and how "the very layout of the ship and the design of the bridge promoted the smooth flow of information from the exterior of the ship to the crew and among the crewmembers" (Bates, 2006, pp. 1042-1043) does not justify Bates' definition of information as an objective phenomenon. The design is made for a purpose, and this purpose determines how information should be defined in this context. Bates' view on "curatorial sciences" (2006, p. 1043) is close to Hjorland's suggestions (2000) about "memory institutions," which is based on the subjective understanding of information. However, she does not relate to this proposal, and she does not argue how the objective understanding of information is related to this example. I therefore conclude that Bates' practical examples do not support her objective definition of information, nor do they support her "having it both ways." Finally, I exemplify the consequences of my understanding of information by showing how an archaeologist and a geologist might represent the same stone differently in information systems. Bates (2008, p. 843) writes about this example: "This position is completely consistent with mine." However, this "consistency" was not recognized by Bates until I published my objections and, therefore, this is an indication that my criticism was needed. I certainly share Professor Bates (2008) advice to read her original articles: They contain much important stuff. I just recommend that the reader ignore the parts that argue about information being an objective phenomenon."

    Abstract
    Information science has for a long time been drawing on the knowledge produced in psychology and related fields. This is reasonable, for the central issue in information science concerns individual users navigating information spaces such as libraries, databases, and the Internet, Thus, informations seeking is the fundamental problem in information science, while other problems, such as document representation, are subordinate. This book proposes a general theory of information seeking as a theoretical basis for information science

    Abstract
    This article presents a theoretical investigation of the concept of 'subject' or 'subject matter' in library and information science. Most conceptions of 'subject' in the literature are not explicit but implicit. Various indexing and classification theories, including automatic indexing and citation indexing, have their own more or less implicit concepts of subject. This fact puts the emphasis on making the implicit theorie of 'subject matter' explicit as the first step. ... The different conceptions of 'subject' can therefore be classified into epistemological positions, e.g. 'subjective idealism' (or the empiric/positivistic viewpoint), 'objective idealism' (the rationalistic viewpoint), 'pragmatism' and 'materialism/realism'. The third and final step is to propose a new theory of subject matter based on an explicit theory of knowledge. In this article this is done from the point of view of a realistic/materialistic epistemology.

    Abstract
    Purpose - To suggest that a theory of classification for information retrieval (IR), asked for by Spärck Jones in a 1970 paper, presupposes a full implementation of a pragmatic understanding. Part of the Journal of Documentation celebration, "60 years of the best in information research". Design/methodology/approach - Literature-based conceptual analysis, taking Sparck Jones as its starting-point. Analysis involves distinctions between "positivism" and "pragmatism" and "classical" versus Kuhnian understandings of concepts. Findings - Classification, both manual and automatic, for retrieval benefits from drawing upon a combination of qualitative and quantitative techniques, a consideration of theories of meaning, and the adding of top-down approaches to IR in which divisions of labour, domains, traditions, genres, document architectures etc. are included as analytical elements and in which specific IR algorithms are based on the examination of specific literatures. Introduces an example illustrating the consequences of a full implementation of a pragmatist understanding when handling homonyms. Practical implications - Outlines how to classify from a pragmatic-philosophical point of view. Originality/value - Provides, emphasizing a pragmatic understanding, insights of importance to classification for retrieval, both manual and automatic. - Vgl. auch: Szostak, R.: Classification, interdisciplinarity, and the study of science.

    Abstract
    It is with very great pleasure that we introduce this special issue of Knowledge Organization on Domain Analysis (DA). Domain analysis is an approach to information science (IS) that emphasizes the social, historical, and cultural dimensions of information. It asserts that collective fields of knowledge, or "domains," form the unit of analysis of information science (IS). DA, elsewhere referred to as a sociocognitive (Hjoerland, 2002b; Jacob & Shaw, 1998) or collectivist (Talja et al, 2004) approach, is one of the major metatheoretical perspectives available to IS scholars to orient their thinking and research. DA's focus an domains stands in contrast to the alternative metatheories of cognitivism and information systems, which direct attention to psychological processes and technological processes, respectively. The first comprehensive international formulation of DA as an explicit point of view was Hjoerland and Albrechtsen (1995). However, a concern for information in the context of a community can be traced back to American library historian and visionary Jesse Shera, and is visible a century ago in the earliest practices of special librarians and European documentalists. More recently, Hjoerland (1998) produced a domain analytic study of the field of psychology; Jacob and Shaw (1998) made an important interpretation and historical review of DA; while Hjoerland (2002a) offered a seminal formulation of eleven approaches to the study of domains, receiving the ASLIB 2003 Award. Fjordback Soendergaard; Andersen and Hjoerland (2003) suggested an approach based an an updated version of the UNISIST-model of scientific communication. In fall 2003, under the conference theme of "Humanizing Information Technology" DA was featured in a keynote address at the annual meeting of the American Society for Information Science and Technology (Hjorland, 2004). These publications and events are evidence of growth in representation of the DA view. To date, informal criticism of domain analysis has followed two tracks. Firstly, that DA assumes its communities to be academic in nature, leaving much of human experience unexplored. Secondly, that there is a lack of case studies illustrating the methods of domain analytic empirical research. Importantly, this special collection marks progress by addressing both issues. In the articles that follow, domains are perceived to be hobbies, professions, and realms of popular culture. Further, other papers serve as models of different ways to execute domain analytic scholarship, whether through traditional empirical methods, or historical and philosophical techniques. Eleven authors have contributed to this special issue, and their backgrounds reflect the diversity of interest in DA. Contributors come from North America, Europe, and the Middle East. Academics from leading research universities are represented. One writer is newly retired, several are in their heyday as scholars, and some are doctoral students just entering this field. This range of perspectives enriches the collection. The first two papers in this issue are invited papers and are, in our opinion, very important. Anders Oerom was a senior lecturer at the Royal Scbool of 'Library and Information Science in Denmark, Aalborg Branch. He retired from this position an March 1, 2004, and this paper is his last contribution in this position. We are grateful that he took the time to complete "Knowledge Organization in the Domain of Art Studies - History, Transition and Conceptual Changes" in spite of many other duties. Versions of the paper have previously been presented at a Ph.D-course in knowledge organization and related versions have been published in Danish and Spanish. In many respects, it represents a model of how a domain could, or should, be investigated from the DA point of view.
    It uncovers the main theoretical influences that have affected the representation of art in systems of knowledge organization such as LCC, DDC, UDC and the Art & Architecture Thesaurus, and it provides a deep basis for evaluating such systems. Knut Tore Abrahamsen's "Indexing of Musical Genres. An Epistemological Perspective" is a modified version of a thesis written at the Royal School of Library and Information Science in Copenhagen. As a thesis it is a major achievement which successfully combines knowledge of music, epistemology, and knowledge organization. This paper may also be seen as an example of how domains can be analyzed and how knowledge organization may be improved in practice. We would like to thank Sanna Talja of the University of Tampere, among other people, for Input an this piece. And now to the rest of the issue: Olof Sundin's "Towards an Understanding of Symbolic Aspects of Professional Information: an Analysis of the Nursing Knowledge Domain" contributes to DA by introducing a deeper understanding of the notion of professions and by uncovering how in some domains, "symbolic" functions of information may be more important than instrumental functions. Rich Gazan's: "Metadata as a Realm of Translation: Merging Knowledge Domains in the Design of an Environmental Information System" demonstrates the problems of merging data collections in interdisciplinary fields, rohen the perceived informational value of different access points varies with disciplinary membership. This is important for the design of systems of metadata. Joe Tennis': "Two Axes of Domains for Domain Analysis" suggests that the notion of domain is underdeveloped in DA. Tennis states, "Hjoerland has provided a hammer, but rohere are the nails?" In addition he raises a question concerning the degree of specialization within a domain. He resolves these issues by proposing two new "axes" to DA. Chaim Zins & David Guttmann's: "Domain Analysis of Social Work: An Example of an Integrated Methodological Approach" represents an empirical approach to the construction of knowledge maps based an representative samples of the literature an social work. In a way, this paper is the most traditional or straightforward approach to knowledge organization in the issue: It suggests a concrete classification based an scientific norms of representation and objectivity.
    Hanne Albrechtsen & Annelise Mark Pejtersen's: "Cognitive Work Analysis and Work Centered Design of Classification Schemes" is also based an empirical studies, but focuses an work groups rather than literatures. It claims that deep semantic structures relevant to classification evolve dynamically in work groups. Its empirical method is different from Zins & Guttmann's. Future research must further uncover the relative strengths and weaknesses of literatures versus people in the construction of knowledge organizing systems. Jenna Hartel's: "The Serious Leisure Frontier in Library and Information Science: Hobby Domains" expands DA to the field of "everyday information use" and demonstrates that most of the approaches suggested by Hjoerland (2002a) may also be relevant to this field. Finally, Birger Hjoerland & Jenna Hartel's After-word: Some Basic Issues Related to the Notion of a Domain" suggests that the notions of ontology, epistemology, and sociology may be three fundamental dimensions of domains and that these perspectives may clarify what domains are and the dynamics of their development. While this special issue marks great progress, and the zenith of DA to date, the approach remains emergent and there is still much work to be done. We see the need for ongoing domain analytic research along two paths. Remarkably, to our knowledge no domain has been thoroughly studied in the domain analytic view. The first order, then, is rigorous application of DA to multiple domains. Second, theoretical and methodological gaps presently exist; these are opportunities for creative inventors to contribute original extensions to the approach. We warmly invite all readers to seriously engage with these articles, whether as critics, spectators, or participants in the domain analytic project.

    Abstract
    It is argued that concepts are the building blocks of knowledge organizing systems (KOS). Objections to this view are considered and answers are provided. By implication the theory of concepts constitutes the foundation for knowledge organization (KO). The theory of concepts is understood as related to and derived from theories of knowledge. Different theories of knowledge such as empiricism, rationalism, historicism and pragmatism imply different theories of concepts. Such different epistemologies and their associated theories of concepts represent different methodological ideals which probably compete in all knowledge domains. Different approaches to KO are also in fundamental ways associated with different theories of concepts. The paper holds that the historicist and pragmatic theory of concept should be considered most valuable. By implication is it is necessary to know about competing theories in the fields being organized. A further implication of the pragmatic view is that the construction of a KOS must be understood as a way of participating in the discourses in the domain that is being represented.

    Abstract
    This article discusses the different meanings of 'keyword' and related terms such as 'keyphrase', 'descriptor', 'index term', 'subject heading', 'tag' and 'n-gram' and suggests definitions of each of these terms. It further illustrates a classification of keywords, based on how they are produced or who is the actor generating them and present comparison between author-assigned keywords, indexer-assigned keywords and reader-assigned keywords as well as the automatic generation of keywords. The article also considers the functions of keywords including the use of keywords for generating bibliographic indexes. The theoretical view informing the article is that the assignment of a keyword to a text, picture or other document involves an interpretation of the document and an evaluation of the document's potentials for users. This perspective is important for both manually assigned keywords and for automated generation and is opposed to a strong tendency to consider a set of keywords as ideally presenting one best representation of a document for all requests.

    Abstract
    Theories of aboutness and theories of subject analysis and of related concepts such as topicality are often isolated from each other in the literature of information science (IS) and related disciplines. In IS it is important to consider the nature and meaning of these concepts, which is closely related to theoretical and metatheoretical issues in information retrieval (IR). A theory of IR must specify which concepts should be regarded as synonymous concepts and explain how the meaning of the nonsynonymous concepts should be defined

    Abstract
    This article presents a brief history of the term "information" and its different meanings, which are both important and difficult because the different meanings of the term imply whole theories of knowledge. The article further considers the relation between "information" and the concepts "matter and energy", "data", "sign and meaning", "knowledge" and "communication". It presents and analyses the influence of information in information studies and knowledge organization and contains a presentation and critical analysis of some compound terms such as "information need", "information overload" and "information retrieval", which illuminate the use of the term information in information studies. An appendix provides a chronological list of definitions of information.

    Abstract
    Purpose - The purpose of this research is to examine the practical potentials of Bradford's law in relation to core-journal identification. Design/methodology/approach - Literature studies and empirical tests (Bradford analyses). Findings - Literature studies reveal that the concept of "subject" has never been explicitly addressed in relation to Bradford's law. The results of two empirical tests (Bradford analyses) demonstrate that different operationalizations of the concept of "subject" produce quite different lists of core-journals. Further, an empirical test reveals that Bradford analyses function discriminatorily against minority views. Practical implications - Bradford analysis can no longer be regarded as an objective and neutral method. The received view on Bradford's law needs to be revised. Originality/value - The paper questions one of the old dogmas of the field.

    Abstract
    Purpose The purpose of this paper is to make a critical analysis of the views put forward by Claudio Gnoli (2018) in this paper concerning philosophical problems in library and information science (LIS). Design/methodology/approach The paper presents the basic ideas in Gnoli (2018) and discusses the set of basic assumptions, concepts and conclusions put forward. Findings It is argued that the idea of the theory of levels is basically sound, but we do not need to consider the material world, the mental world (minds) and the world of mentefacts as three different worlds. They represent different levels with different kinds of emergent properties in the world. Further, although the concepts of artifacts and mentefacts are useful, there are other terms within LIS, such as document, work and object that have been influential and should be discussed in this context. It is also argued that subjective vs objective knowledge is often confused with private vs public knowledge, which is problematic. Finally, it is claimed that the cognitive view and the "sociological view" are not about two different levels of reality but are competing views about the same reality. Originality/value The paper clarifies some aspects of the analytical framework of domain analysis and adds to the developments of the philosophical dimensions of information within LIS.

    Abstract
    This article discusses definitions of index and indexing and provides a systematic overview of kinds of indexes. Theories of indexing are reviewed, and the theoretical basis of both manual indexing and automatic indexing is discussed, and a classification of theories is suggested (rationalist, cognitivist, empiricist, and historicist and pragmatist theories). It is claimed that although many researchers do not consider indexing to be a theoretical issue (or consider it to be a field without theories) indexing is indeed highly theory-laden (and the idea of atheoretical indexing is an oxymoron). An important issue is also the subjectivity of the indexer, in particular, her socio-cultural and paradigmatic background, as for example, when authors of documents are the best indexers of their own documents. The article contains a section about the tools available for indexing in the form of the indexing languages and their nature. It is concluded that the social epistemology first proposed by Jesse Shera in 1951 provides the most fruitful theoretical framework for indexing.

    Abstract
    Special classifications have been somewhat neglected in KO compared to general classifications. The methodology of constructing special classifications is important, however, also for the methodology of constructing general classification schemes. The methodology of constructing special classifications can be regarded as one among about a dozen approaches to domain analysis. The methodology of (special) classification in LIS has been dominated by the rationalistic facet-analytic tradition, which, however, neglects the question of the empirical basis of classification. The empirical basis is much better grasped by, for example, bibliometric methods. Even the combination of rational and empirical methods is insufficient. This presentation will provide evidence for the necessity of historical and pragmatic methods for the methodology of classification and will point to the necessity of analyzing "paradigms". The presentation covers the methods of constructing classifications from Ranganathan to the design of ontologies in computer science and further to the recent "paradigm shift" in classification research. 1. Introduction Classification of a subject field is one among about eleven approaches to analyzing a domain that are specific for information science and in my opinion define the special competencies of information specialists (Hjoerland, 2002a). Classification and knowledge organization are commonly regarded as core qualifications of librarians and information specialists. Seen from this perspective one expects a firm methodological basis for the field. This paper tries to explore the state-of-the-art conceming the methodology of classification. 2. Classification: Science or non-science? As it is part of the curriculum at universities and subject in scientific journals and conferences like ISKO, orte expects classification/knowledge organization to be a scientific or scholarly activity and a scientific field. However, very often when information specialists classify or index documents and when they revise classification system, the methods seem to be rather ad hoc. Research libraries or scientific databases may employ people with adequate subject knowledge. When information scientists construct or evaluate systems, they very often elicit the knowledge from "experts" (Hjorland, 2002b, p. 260). Mostly no specific arguments are provided for the specific decisions in these processes.

    Abstract
    This article contrasts Bates' understanding of information as an observer-independent phenomenon with an understanding of information as situational, put forward by, among others, Bateson, Yovits, Spang-Hanssen, Brier, Buckland, Goguen, and Hjorland. The conflict between objective and subjective ways of understanding information corresponds to the conflict between an understanding of information as a thing or a substance versus an understanding of it as a sign. It is a fundamental distinction that involves a whole theory of knowledge, and it has roots back to different metaphors applied in Shannon's information theory. It is argued that a subject-dependent/ situation specific understanding of information is best suited to fulfill the needs in information science and that it is urgent for us to base Information Science (IS; or Library and Information Science, LIS) on this alternative theoretical frame.

    Abstract
    The study on information science (IS) by Bates (2007) is an important contribution to the literature on browsing in IS. It is explicitly based on "behavioural science." I use this article as the point of departure for demonstrating how more social and interpretative understandings may provide fruitful improvements for research in information seeking, browsing, and related phenomena. It is part of my ongoing publication of articles about philosophical issues in IS and it is intended to be accompanied by analyses of other examples of contributions to core issues in IS. Although it is mainly formulated as a discussion based on a specific paper, it should be seen as part of a general discussion of the philosophical foundation of IS and as support for the emerging social paradigm in this field. The article argues that human browsing should not be conceptualized primarily in biological terms and should not be understood as random exploratory processes, but rather it should be seen as a kind of orienting strategy governed by people's metatheories or "paradigms." Information professionals should know how different metatheories are distributed in the information ecology and, thus, be able to help people developing fruitful browsing strategies.

    Abstract
    Domains are basically constituted of three kinds of theories and concepts: (1) ontological theories and concepts about the objects of human activity; (2) epistemological theories and concepts about knowledge and the ways to obtain knowledge, implying methodological principles about the ways objects are investigated; and (3) sociological concepts about the groups of people concerned with the objects. There are complicated relations between these elements. Basic theories about those relationships are, for example, forms of philosophical realism and social constructivism. In this paper these concepts and theories are introduced, and their implications for knowledge organization outlined, with illustrations drawn from this special issue of Knowledge Organization.
