    Abstract
    Recent revision of UDC classes has aimed at implementing a more faceted approach. Many compound classes have been removed from the main tables, and more radical revisions of classes (particularly those for Medicine and Religion) have introduced a rigorous analysis, a clearer sense of citation order, and building of compound classes according to a more logical system syntax. The faceted approach provides a means of formalizing the relationships in the classification and making them explicit for machine recognition. In the Bliss Bibliographic Classification (BC2) (which has been a source for both UDC classes mentioned above), terminologies are encoded for automatic generation of hierarchical and associative relationships. Nevertheless, difficulties are encountered in vocabulary control, and a similar phenomenon is observed in UDC. Current work has revealed differences in the vocabulary of humanities and science, notably the way in which terms in the humanities should be handled when these are semantically complex. Achieving a balance between rigour in the structure of the classification and the complexity of natural language expression remains partially unresolved at present, but provides a fertile field for further research.

    Abstract
    Facet analysis is proposed as a general theory of knowledge organization, with an associated methodology that may be applied to the development of terminology tools in a variety of contexts and formats. Faceted classifications originated as a means of representing complexity in semantic content that facilitates logical organization and effective retrieval in a physical environment. This is achieved through meticulous analysis of concepts, their structural and functional status (based on fundamental categories), and their inter-relationships. These features provide an excellent basis for the general conceptual modelling of domains, and for the generation of KOS other than systematic classifications. This is demonstrated by the adoption of a faceted approach to many web search and visualization tools, and by the emergence of a facet based methodology for the construction of thesauri. Current work on the Bliss Bibliographic Classification (Second Edition) is investigating the ways in which the full complexity of faceted structures may be represented through encoded data, capable of generating intellectually and mechanically compatible forms of indexing tools from a single source. It is suggested that a number of research questions relating to the Semantic Web could be tackled through the medium of facet analysis.

    Abstract
    The paper traces the development of the discussion around ethical issues in artificial intelligence, and considers the way in which humans have affected the knowledge bases used in machine learning. The phenomenon of bias or discrimination in machine ethics is seen as inherited from humans, either through the use of biased data or through the semantics inherent in intellectually- built tools sourced by intelligent agents. The kind of biases observed in AI are compared with those identified in the field of knowledge organization, using religious adherents as an example of a community potentially marginalized by bias. A practical demonstration is given of apparent religious prejudice inherited from source material in a large database deployed widely in computational linguistics and automatic indexing. Methods to address the problem of bias are discussed, including the modelling of the moral process on neuroscientific understanding of brain function. The question is posed whether it is possible to model religious belief in a similar way, so that robots of the future may have both an ethical and a religious sense and themselves address the problem of prejudice.

    Abstract
    Purpose - The purpose of this editorial is to introduce the selected Proceedings of the 1st National Conference of ISKO UK, the UK Chapter of the International Society for Knowledge Organization. It aims to provide some background for the group, and place it within the context of the recent history of information organization and retrieval in subject domains. Design/methodology/approach - The paper introduces a selection of papers delivered at the 1st National Conference of the UK Chapter of the International Society for Knowledge Organization. Findings - The field of knowledge organization is lively and progressive, and researchers and practitioners in many sectors are actively engaged with it, despite its apparent decline in LIS education. New communities of interest may use different terms to describe this work, but there is much common ground, and a growing convergence of ideas and methods. Originality/value - The value of existing theory is now more widely recognised, and the importance of structured knowledge organization systems and vocabularies in retrieval is generally acknowledged. It is to be hoped that these important areas of information practice and research will soon be restored to their former place in professional education.
