- Abstract
- In this century, knowledge creation, production, dissemination and use have changed profoundly. Intellectual and physical barriers have been substantially reduced by the rise of multidisciplinarity and by the influence of computerization, particularly by the spread of the World Wide Web (WWW). Bibliographic classification systems need to respond to this situation. Three possible strategic responses are described: 1) adopting an existing system; 2) adapting an existing system; and 3) finding new structural principles for classification systems. Examples of these three responses are given. An extended example of the third option uses the knowledge outline in the Spectrum of Britannica Online to suggest a theory of "viewpoint warrant" that could be used to incorporate differing perspectives into general classification systems

- Abstract
- Disciplines are felt by many to be a constraint in classification, though they are a structuring principle of most bibliographic classification schemes. A non-disciplinary approach has been explored by the Classification Research Group, and research in this direction has been resumed recently by the Integrative Level Classification project. This paper focuses on the role and the definition of facets in non-disciplinary schemes. A generalized definition of facets is suggested with reference to predicate logic, allowing for having facets of phenomena as well as facets of disciplines. The general categories under which facets are often subsumed can be related ontologically to the evolutionary sequence of integrative levels. As a facet can be semantically connected with phenomena from any other part of a general scheme, its values can belong to three types, here called extra-defined foci (either special or general), and context-defined foci. Non-disciplinary freely faceted classification is being tested by applying it to little bibliographic samples stored in a MySQL database, and developing Web search interfaces to demonstrate possible uses of the described techniques.

- Abstract
- Purpose - Classification is an important process in making sense of the world, and has a pronounced social dimension. This paper aims to compare folksonomy, a new social classification system currently being developed on the web, with conventional taxonomy in the light of theoretical sociological and anthropological approaches. The co-existence of these two types of classification system raises the questions: Will and should taxonomies be hybridized with folksonomies? What can each of these systems contribute to information-searching processes, and how can the sociology of knowledge provide an answer to these questions? This paper aims also to address these issues. Design/methodology/approach - This paper is situated at the meeting point of the sociology of knowledge, epistemology and information science and aims at examining systems of classification in the light of both classical theory and current late-modern sociological and anthropological approaches. Findings - Using theoretical approaches current in the sociology of science and knowledge, the paper envisages two divergent possible outcomes. Originality/value - While concentrating on classifications systems, this paper addresses the more general social issue of what we know and how it is known. The concept of hybrid knowledge is suggested in order to illuminate the epistemological basis of late-modern knowledge being constructed by hybridizing contradictory modern knowledge categories, such as the subjective with the objective and the social with the natural. Integrating tree-like taxonomies with folksonomies or, in other words, generating a naturalized structural order of objective relations with social, subjective classification systems, can create a vast range of hybrid knowledge.

- Abstract
- The spread of many new media and formats is changing the scenario faced by knowledge organizers: as printed monographs are not the only standard form of knowledge carrier anymore, the traditional kind of knowledge organization (KO) systems based on academic disciplines is put into question. A sounder foundation can be provided by an analysis of the different dimensions concurring to form the content of any knowledge item-what Brian Vickery described as the steps "from the world to the classifier." The ultimate referents of documents are the phenomena of the real world, that can be ordered by ontology, the study of what exists. Phenomena coexist in subjects with the perspectives by which they are considered, pertaining to epistemology, and with the formal features of knowledge carriers, adding a further, pragmatic layer. All these dimensions can be accounted for in metadata, but are often done so in mixed ways, making indexes less rigorous and interoperable. For example, while facet analysis was originally developed for subject indexing, many "faceted" interfaces today mix subject facets with form facets, and schemes presented as "ontologies" for the "semantic Web" also code for non-semantic information. In bibliographic classifications, phenomena are often confused with the disciplines dealing with them, the latter being assumed to be the most useful starting point, for users will have either one or another perspective. A general citation order of dimensions- phenomena, perspective, carrier-is recommended, helping to concentrate most relevant information at the beginning of headings.

- Abstract
- Previously, the main problem of information extraction was to gather enough data. Today, the challenge is not to collect data but to interpret and represent them in order to deduce information. Ontologies are considered suitable solutions for organizing information. The classic methods for ontology construction from textual documents rely on natural language analysis and are generally based on statistical or linguistic approaches. However, these approaches do not consider the document structure which provides additional knowledge. In fact, the structural organization of documents also conveys meaning. In this context, new approaches focus on document structure analysis to extract knowledge. This paper describes a methodology for ontology construction from web data and especially from Wikipedia articles. It focuses mainly on document structure in order to extract the main concepts and their relations. The proposed methods extract not only taxonomic and non-taxonomic relations but also give the labels describing non-taxonomic relations. The extraction of non-taxonomic relations is established by analyzing the titles hierarchy in each document. A pattern matching is also applied in order to extract known semantic relations. We propose also to apply a refinement to the extracted relations in order to keep only those that are relevant. The refinement process is performed by applying the transitive property, checking the nature of the relations and analyzing taxonomic relations having inverted arguments. Experiments have been performed on French Wikipedia articles related to the medical field. Ontology evaluation is performed by comparing it to gold standards.

- Abstract
- Shiyali Ramamrita Ranganathan's theory of classification spans a number of works over a number of decades. And while he was devoted to solving many problems in the practice of librarianship, and is known as the father of library science in India (Garfield, 1984), his work in classification revolves around one central concern. His classification research addressed the problems that arose from introducing new ideas into a scheme for classification, while maintaining a meaningful hierarchical and systematically arranged order of classes. This is because hierarchical and systematically arranged classes are the defining characteristic of useful classification. To lose this order is to through the addition of new classes is to introduce confusion, if not chaos, and to move toward a useless classification - or at least one that requires complete revision. In the following chapter, I outline the stages, and the elements of those stages, in Ranganathan's thought on classification from 1926-1972, as well as posthumous work that continues his agenda. And while facets figure prominently in all of these stages; but for Ranganathan to achieve his goal, he must continually add to this central feature of his theory of classification. I will close this chapter with an outline of persistent problems that represent research fronts for the field. Chief among these are what to do about scheme change and the open question about the rigor of information modeling in light of semantic web developments.
