Abstract

This is the fourth in a series of papers on classification based on phenomena instead of disciplines. Together with types, levels and facets that have been discussed in the previous parts, themes and rhemes are further structural components of such a classification. In a statement or in a longer document, a base theme and several particular themes can be identified. Base theme should be cited first in a classmark, followed by particular themes, each with its own facets. In some cases, rhemes can also be expressed, that is new information provided about a theme, converting an abstract statement ("wolves, affected by cervids") into a claim that some thing actually occurs ("wolves are affected by cervids"). In the Integrative Levels Classification rhemes can be expressed by special deictic classes, including those for actual specimens, anaphoras, unknown values, conjunctions and spans, whole universe, anthropocentric favoured classes, and favoured host classes. These features, together with rules for pronounciation, make a classification of phenomena a true language, that may be suitable for many uses.

Abstract

Marc Bloch's famous methodological essay, The Historian's Craft, contains many relevant considerations on knowledge organization. These have been selected and grouped into four main themes: terminology problems in history; principles for the organization of historical knowledge, with special reference to the genetic principle; sources of historical information, to be found not only in archives but also in very different media and contexts; and the nature and boundaries of history as a discipline. Analysis of them shows that knowledge organization is an important part of historians' work, and suggests that it can be especially fruitful when a cross-medial, interdisciplinary approach is adopted.

Abstract

Exploring collections by their subject matter is an important functionality for library users. We developed an online tool called SciGator in order to allow users to browse the Dewey Decimal Classification (DDC) classes used in different libraries at the University of Pavia and to perform different types of search in the OPAC. Besides navigation of DDC hierarchies, SciGator suggests "see-also" relationships with related classes and maps equivalent classes in local shelving schemes, thus allowing the expansion of search queries to include subjects contiguous to the initial one. We are developing new features, including the possibility to expand searches even more to national and international catalogues.

Abstract

The Integrative Level Classification (ILC) research project is experimenting with a knowledge organization system based on phenomena rather than disciplines. Each phenomenon has a constant notation, which can be combined with that of any other phenomenon in a freely faceted structure. Citation order can express differential focality of the facets. Very specific subjects can have long classmarks, although their complexity is reduced by various devices. Freely faceted classification is being tested by indexing a corpus of about 3300 papers in the interdisciplinary domain of bioacoustics. The subjects of these papers often include phenomena from a wide variety of integrative levels (mechanical waves, animals, behaviour, vessels, fishing, law, ...) as well as information about the methods of study, as predicted in the León Manifesto. The archive is recorded in a MySQL database, and can be fed and searched through PHP Web interfaces. Indexer's work is made easier by mechanisms that suggest possible classes on the basis of matching title words with terms in the ILC schedules, and synthesize automatically the verbal caption corresponding to the classmark being edited. Users can search the archive by selecting and combining values in each facet. Search refinement should be improved, especially for the cases where no record, or too many records, match the faceted query. However, experience is being gained progressively, showing that freely faceted classification by phenomena, theories, and methods is feasible and successfully working.

Abstract

Although bibliographic classifications usually adopt a perspective different from that of object classifications, the two have obvious relationships. These become especially relevant when users are looking for knowledge scattered in a wide variety of forms and media. This is an increasingly common situation, as library catalogues now coexist in the global digital environment with catalogues of archives, of museums, of commercial products, and many other information resources. In order to make the subject content of all these resources searchable, a broader conception of classification is needed, that can be applied to an knowledge item, rather than only bibliographic materials. To illustrate this we take an example of the research on bagpipes in Northern Italian folklore. For this kind of research, the most effective search strategy is a cross-media one, looking for many different knowledge sources such as published documents, police archives, painting details, museum specimens, organizations devoted to related subjects. To provide satisfying results for this kind of search, the traditional disciplinary approach to classification is not sufficient. Tools are needed in which knowledge items dealing with a phenomenon of interest can be retrieved independently from the other topics with which it is combined, the disciplinary context, and the medium where it occurs. This can be made possible if the basic units of classification are taken to be the phenomena treated, as recommended in the León Manifesto, rather than disciplines or other aspect features. The concept of bagpipes should be retrievable and browsable in any combination with other phenomena, disciplines, media etc. Examples are given of information sources that could be managed by this freely-faceted technique of classification.

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

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

One general principle in the construction of classification schemes is that of grouping phenomena to be classified according to their shared origin in evolution or history (phylogenesis). In general schemes, this idea has been applied by several classificationists in identifying a series of integrative levels, each originated from the previous ones, and using them as the main classes. In special schemes, common origin is a key principle in many domains: examples are given from the classification of climates, of organisms, and of musical instruments. Experience from these domains, however, suggests that using common origin alone, as done in cladistic taxonomy, can produce weird results, like having birds as a subclass of reptiles; while the most satisfying classifications use a well balanced mix of common origin and similarity. It is discussed how this could be applied to the development of a general classification of phenomena in an emergentist perspective, and how the resulting classification tree could be structured. Charles Bennett's notion of logical depth appears to be a promising conceptual tool for this purpose.

Abstract

Facets and general categories used in bibliographic classification have been based on a disciplinary organization of knowledge. However, facets and categories of phenomena independent from disciplines can be identified similarly. Phenomena can be classified according to a series of integrative levels (layers), which in turn can be grouped into the major strata of form, matter, life, mind, society and culture, agreeing with Nicolai Hartmann's ontology. Unlike a layer, a stratum is not constituted of elements of the lower ones; rather, it represents the formal pattern of the lower ones, like the horse hoof represents the shape of the steppe. Bibliographic categories can now be seen in the light of level theory: some categories are truly general, while others only appear at a given level, being the realization of a general category in the specific context of the level: these are the facets of that level. In the notation of the Integrative Level Classification project, categories and facets are represented by digits, and displayed in a Web interface with the help of colours.

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

In traditional classification, fictional works are indexed only by their form, genre, and language, while their subject content is believed to be irrelevant. However, recent research suggests that this may not be the best approach. We tested indexing of a small sample of selected fictional works by Integrative Levels Classification (ILC2), a freely faceted system based on phenomena instead of disciplines and considered the structure of the resulting classmarks. Issues in the process of subject analysis, such as selection of relevant vs. non-relevant themes and citation order of relevant ones, are identified and discussed. Some phenomena that are covered in scholarly literature can also be identified as relevant themes in fictional literature and expressed in classmarks. This can allow for hybrid search and retrieval systems covering both fiction and nonfiction, which will result in better leveraging of the knowledge contained in fictional works.

Abstract

Subjects in a classification scheme are often related to other subjects belonging to different hierarchies. This problem was identified already by Hugh of Saint Victor (1096?-1141). Still with present-time bibliographic classifications, a user browsing the class of architecture under the hierarchy of arts may miss relevant items classified in building or in civil engineering under the hierarchy of applied sciences. To face these limitations we have developed SciGator, a browsable interface to explore the collections of all scientific libraries at the University of Pavia. Besides showing subclasses of a given class, the interface points users to related classes in the Dewey Decimal Classification, or in other local schemes, and allows for expanded queries that include them. This is made possible by using a special field for related classes in the database structure which models classification authority data. Ontologically, many relationships between classes in different hierarchies are cases of existential dependence. Dependence can occur between disciplines in such disciplinary classifications as Dewey (e.g. architecture existentially depends on building), or between phenomena in such phenomenon-based classifications as the Integrative Levels Classification (e.g. fishing as a human activity existentially depends on fish as a class of organisms). We provide an example of its representation in OWL and discuss some details of it.

Abstract

This special issue of ''Axiomathes'' is devoted to a technique originally developed within library science: facet analysis. During discussions with Roberto Poli, it was realized that facet analysis shares interesting features with analytical methods in several other fields, including philosophy, psychology, linguistics, and computer science. For these reasons, in an interdisciplinary spirit, we believe that facet analysis is a relevant topic for the scope of this journal. It is hoped that readers will be persuaded by this after examining the present contributions.

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

Three major principles in the structure of knowledge organization systems are identified and discussed: hierarchical trees of types, sets of facets conforming to general categories, and series of levels of reality. Each principle can be present at various degrees in different systems. The three principles can interact between them in various ways, depending on priority choices in system construction. Examples are reviewed of different priority options adopted in classifications and thesauri, both special and general, and their effects are critically examined. It is found that levels of reality, although less often explicitly acknowledged than other principles, contribute an important tool for knowledge organization.

Abstract

Faceted knowledge organization systems have sophisticated logical structures, making their representation as linked data a demanding task. The term facet is often used in ambiguous ways: while in thesauri facets only work as semantic categories, in classification schemes they also have syntactic functions. The need to convert the Integrative Levels Classification (ILC) into SKOS stimulated a more general analysis of the different kinds of syntactic facets, as can be represented in terms of RDF properties and their respective domain and range. A nomenclature is proposed, distinguishing between common facets, which can be appended to any class, that is, have an unrestricted domain; and special facets, which are exclusive to some class, that is, have a restricted domain. In both cases, foci can be taken from any other class (unrestricted range: free facets), or only from subclasses of an existing class (parallel facets), or be defined specifically for the present class (bound facets). Examples are given of such cases in ILC and in the Dewey Decimal Classification (DDC).

Abstract

As an Italian chapter of ISKO has recently been reorganized, I was kindly invited to Write a short report an current KO activities in our country. So, in the following, I will briefly illustrate the local situation of the various kinds of knowledge organization systems, as well as related developments and activities. I am grateful to Paola Capitani, Emanuela Casson, Michele Santoro, and Lorena Zuccolo for providing useful information to be included here.

"Subject headings Many Italian libraries create subject headings for their catalogues, using as a reference guide the "Soggettario per i catalogui delle biblioteche italiane." This is basically a list of subject terms created by the Biblioteca nazionale centrale di Firenze (BNCF), first published in 1956 and later updated with various lists of new subject headings. Though the Soggettario is still the main available reference, librarians are generally aware that it is outdated in both vocabulary and structure, especially as it does not provide explicit principles and rules to create and combine subject headings. A research group, called the Gruppo di ricerca sull'indicizzazione per soggetto (GRIS), was founded in 1990. It was devoted to improving the principles and consistency of subject indexing. Its members have performed in depth investigations of the structure of subject headings, starting with the principles of facet analysis used in PRECIS and including original developments. Results of their work are coded into the Guida all'indicizzazione per soggetto, published in 1996 and available also online <http:// wwwaib.it/aib/commiss/gris/gulda.htm>. The GRIS guide does not concern vocabulary, but morphological and syntactical rules for choosing and combining terms according to a sound citation order, based an a "role scheme." Unfortunately, GRIS principles have been applied only in a small number of libraries, mainly in Tuscany, rohere most GRIS members are located. A new project is now attempting to blend the traditional authority of the Soggettario with the more advanced principles of GRIS. A working group has been formed with people from BNCF, GRIS, and others, to study the feasibility of a renewal of the Soggettario. The group produced a report book in 2002, specifying the desirable features of the new system, and is at present searching for grants to implement it.
Terminology and thesauri BNCF is also involved in a working group collecting information an online terminological resources <http://wwwindire.it/websemantico>. The group is headed by Paola Capitani, and has organized several roundtables an terminology in special domains, such as economy, fashion, law, and education. Thesauri are generally poorly known and used in Italy, although there are significant exceptions: among faceted systems we can mention the "Thesauro italiano di sociologia," published in 1999, and the "Thesaurus regionale toscano," as well as specialized an social sciences including a general outline, available both in print (1996) and online <http:// www regione.toscana.it/ius/ns-thesaurus/>. Classification systems The Dewey Decimal Classification (DDC) is by far the most widespread classification scheme in Italian libraries. A working group, coordinated by Luigi Crocetti, regularly translates the new editions of DDC manuals, and gives refresher courses an it for librarians. BNCF makes DDC numbers for bibliographical records both of its own catalogue, and of the national bibliography (= Bibliografia nazionale italiana: BNI), which is available for other libraries in a CD-ROM edition. A very large number of public libraries use DDC for their shelfmarks, so that users are accustomed to it. This situation is different from other European countries, e.g., Spain where UDC is widespread."

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.

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.
