    Abstract
    In this paper a model for understanding the concept of information is presented and how the processes of externalization and perception of information by human beings could be understood. This model is different from the standard information theoretic model. It combines the understanding of cognitive information processing as an act of information generation from sense impressions with communication theoretic considerations. This approach can be of value for any system that is regarded as a knowledge system with an in-built ordering structure. As an application some consequences will be drawn for the design of information systems which claims to handle information itself (e.g. multimedia information systems) instead of giving references to bibliographic entities

    Abstract
    We provide a model for the reception of knowledge from externalized information sources. The model is based on a cognitive understanding of information processing and draws up ideas of an exchange of information in communication processes. Karl Popper's three-world theory with its orientation on falsifiable scientific knowledge is extended by John Searle's concept of collective intentionality. This allows a consistent description of externalization and reception of knowledge including scientific knowledge as well as everyday knowledge.

    Abstract
    Information literacy and autonomy have become key values for the image of man in a society that is increasingly shaped by digitalization and artificial intelligence. The purpose of this book is to describe abstraction, analogy, inference, plausibility and creativity as basic skills of cognitive information processing and prerequisites for autonomous informational action.

    Abstract
    Faceted arrangement of entities and typed relations for representing different associations between the entities are established tools in knowledge representation. In this paper, a proposal is being discussed combining both tools to draw inferences along relational paths. This approach may yield new benefit for information retrieval processes, especially when modeled for heterogeneous environments in the Semantic Web. Faceted arrangement can be used as a selection tool for the semantic knowledge modeled within the knowledge representation. Typed relations between the entities of different facets can be used as restrictions for selecting them across the facets.

    Abstract
    In this paper the following problem is discussed: Which possibilities exist to integrate localized knowledge into knowledge structures like classification systems or other documentary languages for the design of OPACs and information systems? It is proposed to combine a de-localized classificatory structure - best describes as 'ontological spine' - with multilingual semantic networks. Each of these networks should represent the respective localized knowledge along an extended set of typed semantic relations serving as entry points vocabulary as well as a semantic basis for navigational purposes within the localized knowledge context. The spine should enable a link between well-known and not well-known knowledge structures.

    Abstract
    The presented ontology-based model for indexing and retrieval combines the methods and experiences of traditional indexing languages with their cognitively interpreted entities and relationships with the strengths and possibilities of formal knowledge representation. The core component of the model uses inferences along the paths of typed relations between the entities of a knowledge representation for enabling the determination of result sets in the context of retrieval processes. A proposal for a general, but condensed, inventory of typed relations is given. The entities are arranged in aspect-oriented facets to ensure a consistent hierarchical structure. The possible consequences for indexing and retrieval are discussed.

    Abstract
    Faceted arrangement of entities and typed relations for representing different associations between the entities are established tools in knowledge representation. In this paper, a proposal is being discussed combining both tools to draw inferences along relational paths. This approach may yield new benefit for information retrieval processes, especially when modeled for heterogeneous environments in the Semantic Web. Faceted arrangement can be used as a selection tool for the semantic knowledge modeled within the knowledge representation. Typed relations between the entities of different facets can be used as restrictions for selecting them across the facets.

    Abstract
    A survey is given, how modifications in the field of the information processing and technology have influenced the concepts for teaching and studying the subjects of knowledge organization and information retrieval in German universities for library and information science. The discussion will distinguish between fields of modifications and fields of stability. The fields of the modifications are characterised by procedures and applications in libraries. The fields of stability are characterised by theory and methods

    Starting from an unsolved problem of information retrieval this paper presents an ontology-based model for indexing and retrieval. The model combines the methods and experiences of cognitive-to-interpret indexing languages with the strengths and possibilities of formal knowledge representation. The core component of the model uses inferences along the paths of typed relations between the entities of a knowledge representation for enabling the determination of hit quantities in the context of retrieval processes. The entities are arranged in aspect-oriented facets to ensure a consistent hierarchical structure. The possible consequences for indexing and retrieval are discussed.

    Abstract
    The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
    "Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

    Abstract
    We present an approach for detecting multiword phrases in mathematical text corpora. The method used is based on characteristic features of mathematical terminology. It makes use of a software tool named Lingo which allows to identify words by means of previously defined dictionaries for specific word classes as adjectives, personal names or nouns. The detection of multiword groups is done algorithmically. Possible advantages of the method for indexing and information retrieval and conclusions for applying dictionary-based methods of automatic indexing instead of stemming procedures are discussed.

    Abstract
    Analyses mathematical terminology to give practical hints for assigning subject headings to a book and proposes a method to use for subject analysis. The method is based on connections between the subject-classification scheme of the American Mathematical Society and indexing with subject headings. Gives examples and compares them with LCSH and PRECIS. A thesaurus of mathematics, using PRECIS methods and connecting with the Amercian Mathematical Society classification is desirable. Authors could also classify their own work and the data could be printed with the books

    Abstract
    Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.
