    Abstract
    This book proposes a novel approach to classification, discusses its myriad advantages, and outlines how such an approach to classification can best be pursued. It encourages a collaborative effort toward the detailed development of such a classification. This book is motivated by the increased importance of interdisciplinary scholarship in the academy, and the widely perceived shortcomings of existing knowledge organization schemes in serving interdisciplinary scholarship. It is designed for scholars of classification research, knowledge organization, the digital environment, and interdisciplinarity itself. The approach recommended blends a general classification with domain-specific classification practices. The book reaches a set of very strong conclusions:
    -Existing classification systems serve interdisciplinary research and teaching poorly. -A novel approach to classification, grounded in the phenomena studied rather than disciplines, would serve interdisciplinary scholarship much better. It would also have advantages for disciplinary scholarship. The productivity of scholarship would thus be increased. -This novel approach is entirely feasible. Various concerns that might be raised can each be addressed. The broad outlines of what a new classification would look like are developed. -This new approach might serve as a complement to or a substitute for existing classification systems. -Domain analysis can and should be employed in the pursuit of a general classification. This will be particularly important with respect to interdisciplinary domains. -Though the impetus for this novel approach comes from interdisciplinarity, it is also better suited to the needs of the Semantic Web, and a digital environment more generally. Though the primary focus of the book is on classification systems, most chapters also address how the analysis could be extended to thesauri and ontologies. The possibility of a universal thesaurus is explored. The classification proposed has many of the advantages sought in ontologies for the Semantic Web. The book is therefore of interest to scholars working in these areas as well.

    Abstract
    Ontology, in its philosophical meaning, is the discipline investigating the structure of reality. Its findings can be relevant to knowledge organization, and models of knowledge can, in turn, offer relevant ontological suggestions. Several philosophers in time have pointed out that reality is structured into a series of integrative levels, like the physical, the biological, the mental, and the cultural, and that each level plays as a base for the emergence of more complex levels. More detailed theories of levels have been developed by Nicolai Hartmann and James K. Feibleman, and these have been considered as a source for structuring principles in bibliographic classification by both the Classification Research Group (CRG) and Ingetraut Dahlberg. CRG's analysis of levels and of their possible application to a new general classification scheme based an phenomena instead of disciplines, as it was formulated by Derek Austin in 1969, is examined in detail. Both benefits and open problems in applying integrative levels to bibliographic classification are pointed out.

    Abstract
    Dewey Decimal Classification has been used to organize materials owned by the three scientific libraries at the University of Pavia, and to allow integrated browsing in their union catalogue through SciGator, a home built web-based user interface. Classification acts as a bridge between collections located in different places and shelved according to different local schemes. Furthermore, cross-discipline relationships recorded in the system allow for expanded queries that increase recall. Advantages and possible improvements of such a system are discussed.

    Abstract
    Notations are systems of symbols that can be combined according to syntactical rules to represent meanings in a specialized domain. In knowledge organization, they are systems of numerals, letters and punctuation marks associated to a concept that mechanically produce helpful sequences of them for arranging books on shelves, browsing subjects in directories and displaying items in catalogues. Most bibliographic classification systems, like Dewey Decimal Classification, use a positional notation allowing for expression of increasingly specific subjects by additional digits. However, some notations like that of Bliss Bibliographic Classification are purely ordinal and do not reflect the hierarchical degree of a subject. Notations can also be expressive of the syntactical structure of compound subjects (common auxiliaries, facets etc.) in various ways. In the digital media, notation can be recorded and managed in databases and exploited to provide appropriate search and display functionalities.

    Abstract
    This is the first part of a study on the classification of phenomena. It starts by addressing the status of classification schemes among knowledge organization systems (KOSs), as some features of them have been overlooked in recent reviews of KOS types. It then considers the different dimensions implied in a KOS, which include: the observed phenomena, the cultural and disciplinary perspective under which they are treated, the features of documents carrying such treatment, the collections of such documents as managed in libraries, archives or museums, the information needs prompting to search and use these collections and the people experiencing such different information needs. Until now, most library classification schemes have given priority to the perspective dimension as they first list disciplines. However, an increasing number of voices are now considering the possibility of classification schemes giving priority to phenomena as advocated in the León Manifesto. Although these schemes first list phenomena as their main classes, they can as well express perspective or the other relevant dimensions that occur in a classified item. The independence of a phenomenon-based classification from the institutional divisions into disciplines contributes to giving knowledge organization a more proactive and influential role.

    This paper shows how a variety of theories employed across a range of social sciences could be classified in terms of theory type. In each case, notation within the Integrated Level Classification is provided. The paper thus illustrates how one key element of the Leon Manifesto that scholarly documents should be classified in terms of the theory(ies) applied can be achieved in practice.

    Abstract
    Research can benefit by periodical consideration of its status in a long-term perspective. In knowledge organization (KO), a number of basic questions remain to be addressed in the 21st century. Ten of them are identified and synthetically discussed: (1) Can KO principles be extended to a broader scope, including hypertexts, multimedia, museum objects, and monuments? (2) Can the two basic approaches, ontological and epistemological, be reconciled? (3) Can any ontological foundation of KO be identified? (4) Should disciplines continue to be the structural base of KO? (5) How can viewpoint warrant be respected? (6) How can KO be adapted to local collection needs? (7) How can KO deal with changes in knowledge? (8) How can KO systems represent all the dimensions listed above? (9) How can software and formats be improved to better serve these needs? (10) Who should do KO: information professionals, authors or readers?

    Abstract
    Purpose The current debate between two theoretical approaches in library and information science and knowledge organization (KO), the cognitive one and the sociological one, is addressed in view of their possible integration in a more general model. The paper aims to discuss these issues. Design/methodology/approach Personal knowledge of individual users, as focused in the cognitive approach, and social production and use of knowledge, as focused in the sociological approach, are reconnected to the theory of levels of reality, particularly in the versions of Nicolai Hartmann and Karl R. Popper (three worlds). The notions of artefact and mentefact, as proposed in anthropological literature and applied in some KO systems, are also examined as further contributions to the generalized framework. Some criticisms to these models are reviewed and discussed. Findings Both the cognitive approach and the sociological approach, if taken in isolation, prove to be cases of philosophical monism as they emphasize a single level over the others. On the other hand, each of them can be considered as a component of a pluralist ontology and epistemology, where individual minds and social communities are but two successive levels in knowledge production and use, and are followed by a further level of "objectivated spirit"; this can in turn be analyzed into artefacts and mentefacts. While all these levels are relevant to information science, mentefacts and their properties are its most peculiar objects of study, which make it distinct from such other disciplines as psychology and sociology. Originality/value This analysis shows how existing approaches can benefit from additional notions contributed by levels theory, to develop more complete and accurate models of information and knowledge phenomena.

    Abstract
    Bericht über: Levels of Reality, Seminar, Bolzano (Bozen) Italy, 26-28 September 2007: Ontologies, the knowledge organization systems now widely used in knowledge management applications, take their name from a branch of philosophy. Philosophical ontology deals with the kinds and the properties of what exists, and with how they can be described by categories like entity, attribute, or process. Readers familiar with facet analysis will notice some analogy with the "fundamental categories" of faceted classifications, and this resemblance is not accidental. Indeed, knowledge organization systems use conceptual structures that can be variously reconnected with the categories of ontology. Though having more practical purposes, the ontologies and classifications of information science can benefit of those of philosophy.
    Darin: "However, John Sowa (Vivomind, USA) argued in his speech that the formalized approach, already undertaken by the pioneering project Cyc now having run for 23 years, is not the best way to analyze complex systems. People don't really use axioms in their cognitive processes (even mathematicians first get an idea intuitively, then work on axioms and proofs only at the moment of writing papers). To map between different ontologies, the Vivomind Analogy Engine throws axioms out, and searches instead for analogies in their structures. Analogy is a pragmatic human faculty using a combination of the three logical procedures of deduction, induction, and abduction. Guarino comments that people can communicate without need of axioms as they share a common context, but in order to teach computers how to operate, the requirements are different: he would not trust an airport control system working by analogy."

    Abstract
    The evolution of bibliographic classification schemes, from the end of the 19th century to our time, shows a trend of increasing possibilities to combine concepts in a classmark. While the early schemes, like DDC and LCC, were largely enumerative, more and more synthetic devices have appeared with common auxiliaries, facets, and phase relationships. The last editions of UDC and the UDC-derived FATKS project follow this evolution, by introducing more specific phase relationships and more common auxiliaries, like those for general properties and processes. This agrees with the Farradane's principle that each concept should have a place of unique definition, instead of being re-notated in each context where it occurs. This evolution appears to be unfinished, as even in most synthetic schemes many concepts have a different notation according to the disciplinary main classes where they occur. To overcome this limitation, main classes should be defined in terms of phenomena rather than disciplines: the Integrative Level Classification (ILC) research project is currently exploring this possibility. Examples with UDC, FATKS, and ILC notations are discussed.

    Abstract
    Purpose - The different senses of the term information in physical, biological and social interpretations, and the possibility of connections between them, are addressed. Special attention is paid to Hofkirchner's Unified Theory of Information (UTI), proposing an integrated view in which the notion of information gets additional properties as one moves from the physical to the biological and the social realms. The paper aims to discuss these issues. Design/methodology/approach - UTI is compared to other views of information, especially to two theories complementing several ideas of it: the theory of the hypertextual documental universe ("docuverse") and the theory of integrative levels of reality. Two alternative applications of the complex of these three theories are discussed: a pragmatical, hermeneutic one, and a more ambitious realist, ontological one. The latter can be extended until considering information ("bit") together with matter-energy ("it") as a fundamental element in the world. Problems and opportunities with each view are discussed. Findings - It is found that the common ground for all three theories is an evolutionary approach, paying attention to the phylogenetic connections between the different meanings of information. Research limitations/implications - Other theories of information, like Leontiev's, are not discussed as not especially related to the focus of the approach. Originality/value - The paper builds on previously unnoticed affinities between different families of information-related theories, showing how each of them can provide fruitful complements to the other ones in clarifying the nature of information.

    Abstract
    Purpose The Integrative Levels Classification (ILC) is a comprehensive "freely faceted" knowledge organization system not previously expressed as SKOS (Simple Knowledge Organization System). This paper reports and reflects on work converting the ILC to SKOS representation. Design/methodology/approach The design of the ILC representation and the various steps in the conversion to SKOS are described and located within the context of previous work considering the representation of complex classification schemes in SKOS. Various issues and trade-offs emerging from the conversion are discussed. The conversion implementation employed the STELETO transformation tool. Findings The ILC conversion captures some of the ILC facet structure by a limited extension beyond the SKOS standard. SPARQL examples illustrate how this extension could be used to create faceted, compound descriptors when indexing or cataloguing. Basic query patterns are provided that might underpin search systems. Possible routes for reducing complexity are discussed. Originality/value Complex classification schemes, such as the ILC, have features which are not straight forward to represent in SKOS and which extend beyond the functionality of the SKOS standard. The ILC's facet indicators are modelled as rdf:Property sub-hierarchies that accompany the SKOS RDF statements. The ILC's top-level fundamental facet relationships are modelled by extensions of the associative relationship - specialised sub-properties of skos:related. An approach for representing faceted compound descriptions in ILC and other faceted classification schemes is proposed.

    Abstract
    Several authors remark that categories used in languages, including indexing ones, are affected by cultural biases, and do not reflect reality in an objective way. Hence knowledge organization would essentially be determined by pragmatic factors. However, human categories are connected with the structure of reality through biological bonds, and this allows for a naturalistic approach too. Naturalism has been adopted by Farradane in proposing relational categories, and by Dahlberg and the CRG in applying the theory of integrative levels to general classification schemes. The latter is especially relevant for possible developments in making the structure of schemes independent from disciplines, and in applying it to digital information retrieval.

    Abstract
    Claudio Gnoli of the University of Pavia in Italy and Chair of ISKO Italy, explored the relative merits of classic 'faceted classification' (FC) and 'freely faceted classification' (FFC). In classic FC, the facets (and their relationships) which might be combined to express a compound subject, are restricted to those prescribed as inherent in the subject area. FC is therefore largely bounded by and restricted to a specific subject area. At the other extreme, free classification (as in the Web or folksonomies) allows the combination of values from multiple, disparate domains where the relationships among the elements are often indeterminate, and the semantics obscure. Claudio described how punched cards were an early example of free classification, and cited the coordination of dogs : postmen : bites as one where the absence of defined relationships made the semantics ambiguous

    Abstract
    The ontological approach in the development of KOS is an attempt to overcome the limitations of the traditional epistemological approach. Questions raise about the representation and organization of ontologically-oriented KO units, such as BFO universals or ILC phenomena. The study aims to compare the ontological approaches of BFO and ILC using a hermeneutic approach. We found that the differences between the units of the two systems are primarily due to the formal level of abstraction of BFO and the different organizations, namely the grouping of phenomena into ILC classes that represent complex compounds of entities in the BFO approach. In both systems the use of concepts is considered instrumental, although in the ILC they constitute the intersubjective component of the phenomena whereas in BFO they serve to access the entities of reality but are not part of them.
