    Abstract
    In this article we identify the need for a new theory of data, information, and knowledge. A model is developed that distinguishes between data as directly observable facts, information as structured collections of data, and knowledge as methods of using information. The model is intended to support a wide range of information systems. In the article we develop the use of the model for a semantic information retrieval system using the concept of semantic categories. The likely benefits of this are discussed, though as yet no detailed evaluation has been conducted

    Abstract
    To those outside the field of library science, the name Melvil Dewey (1851-1931) is virtually synonymous with library classification. To those in the field, Dewey has been recognized as the premier classification maker. His enormously successful system (i.e., successful in terms of the wide adoption of the system around the world for over one hundred years) has now undergone nineteen editions. The Dewey Decimal Classification has been translated into more than twenty languages and is the most widely adopted classification scheme in the world. Even in its earliest manifestations, the Dewey Decimal Classification contained features that anticipated modern classification theory. Among these are the use of mnemonics and the commonly applied standard subdivisions, later called "common isolates" by S. R. Ranganathan (q.v.), which are the mainstays of facet analysis and synthesis. The device of standard subdivisions is an indication of the recognition of common aspects that pervade all subjects. The use of mnemonics, whereby recurring concepts in the scheme are represented by the same notation, for example, geographic concepts and language concepts, eased the transition of the Dewey Decimal Classification from a largely enumerative system to an increasingly faceted one. Another significant feature of the Dewey Decimal Classification is the use of the hierarchical notation based an the arabic numeral system. To a large extent, this feature accounts for the wide use and success of the system in the world across language barriers. With the prospect of increasing online information retrieval, the hierarchical notation will have a significant impact an the effectiveness of the Dewey Decimal Classification as an online retrieval tool. Because the notation is hierarchical, for example, with increasing digits in a number representing narrower subjects and decreasing digits indicating broader subjects, the Dewey Decimal Classification is particularly useful in generic searches for broadening or narrowing search results. In the preface to the second edition of his Decimal Classification Dewey explained the features of his "new" system. The excerpt below presents his ideas and theory concerning the rational basis of his classification, the standard subdivisions, the hierarchical notation based an decimal numbers, the use of mnemonics, the relative index, and relative location. It also reflects Dewey's lifelong interest in simplified spelling.

    Abstract
    Für fachspezifische bibliographische Online-Recherchen werden in den meisten Fällen die Ergebnisse nur der verbalen inhaltlichen Erschliessung genutzt (Deskriptoren, Schlagwörter, Stichwörter, Abstract-Texte). Viele bibliographische Datenbanken sind aber auch mit Hilfe von Notationen aus Klassifikationssystemen recherchierbar. Dieser Beitrag behandelt die letztere Form des sachlichen Zugriffs und streicht die Rolle von Notationen ("class codes") als nützliche Ergänzung zur verbalen Recherche heraus. Im ersten Teil werden folgende Fragen thematisiert: In welchem Ausmass sind Klassifikationsschemata als sachliche Zugriffsmöglichkeit in bibliographischen Datenbanken vorhanden? Welcher Art sind diese Schemata und ihre Notationen? Der zweite Teil veranschaulicht mehrere vorteilhafte Möglichkeiten der Anwendung von Notationen bei der bibliographischen Recherche. Der dritte Teil beschäftigt sich mit Änderungen von Klassifikationssystemen - dem Hauptproblem ihrer Verwendung bei der Online-Recherche. Der Rechercheur muss daher nicht nur wissen, wie Klassifikationen zur Verbesserung der Suchstrategie eingesetzt werden, sondern auch, wie Schwierigkeiten dieser Art zu bewältigen sind.

    Abstract
    THESYS is based on the natural language processing of free-text databases. It yields statistically evaluated correlations between words of the database. These correlations correspond to traditional thesaurus relations. The person who has to build a thesaurus is thus assisted by the proposals made by THESYS. THESYS is being tested on commercial databases under real world conditions. It is part of a text processing project at Siemens, called TINA (Text-Inhalts-Analyse). Software from TINA is actually being applied and evaluated by the US Department of Commerce for patent search and indexing (REALIST: REtrieval Aids by Linguistics and STatistics)

    Abstract
    It is first argued that a niche for information science, unclaimed by any other discipline, can be found by admitting the near-autonomy of Popper's World III - the world of objective knowledge. The task of information science can then be defined as the exploration of this world of objective knowledge which is an extension of, but is distinct from, the world of documentation and librarianship. The Popperian ontology then has to be extended to admit the concept of information and its relations to subjective and objective knowledge. The spaces of Popper's three worlds are then considered. It is argued that cognitive and physical spaces are not identical and that this lack of identity creates problems for the proper quantification of information phenomena

    Abstract
    This paper, presented at the Ottawa Conference an the Conceptual Basis of the Classification of Knowledge, in 1971, is one of Fairthorne's more perceptive works and deserves a wide audience, especially as it breaks new ground in classification theory. In discussing the notion of discourse, he makes a "distinction between what discourse mentions and what discourse is about" [emphasis added], considered as a "fundamental factor to the relativistic nature of bibliographic classification" (p. 360). A table of mathematical functions, for example, describes exactly something represented by a collection of digits, but, without a preface, this table does not fit into a broader context. Some indication of the author's intent ls needed to fit the table into a broader context. This intent may appear in a title, chapter heading, class number or some other aid. Discourse an and discourse about something "cannot be determined solely from what it mentions" (p. 361). Some kind of background is needed. Fairthorne further develops the theme that knowledge about a subject comes from previous knowledge, thus adding a temporal factor to classification. "Some extra textual criteria are needed" in order to classify (p. 362). For example, "documents that mention the same things, but are an different topics, will have different ancestors, in the sense of preceding documents to which they are linked by various bibliographic characteristics ... [and] ... they will have different descendants" (p. 363). The classifier has to distinguish between documents that "mention exactly the same thing" but are not about the same thing. The classifier does this by classifying "sets of documents that form their histories, their bibliographic world lines" (p. 363). The practice of citation is one method of performing the linking and presents a "fan" of documents connected by a chain of citations to past work. The fan is seen as the effect of generations of documents - each generation connected to the previous one, and all ancestral to the present document. Thus, there are levels in temporal structure-that is, antecedent and successor documents-and these require that documents be identified in relation to other documents. This gives a set of documents an "irrevocable order," a loose order which Fairthorne calls "bibliographic time," and which is "generated by the fact of continual growth" (p. 364). He does not consider "bibliographic time" to be an equivalent to physical time because bibliographic events, as part of communication, require delay. Sets of documents, as indicated above, rather than single works, are used in classification. While an event, a person, a unique feature of the environment, may create a class of one-such as the French Revolution, Napoleon, Niagara Falls-revolutions, emperors, and waterfalls are sets which, as sets, will subsume individuals and make normal classes.

    Abstract
    Nicht nur das traditionelle bibliothekarische Auskunftsinterview, sondern auch die Befragung bzw. Beratung, die im Zusammenhang mit der bibliothekarischen Dienstleistung des Online Information Retrieval zwischen Rechercheur und Endbenutzer abläuft, ist in der Literatur vielfach praxisbezogener, aber auch theoretischer Abhandlungen. Der gesamte Interviewprozeß läßt sich in 4 Phasen gliedern, deren zweite, das der Recherche vorausgehende 'Presearch-Interview' im engeren Sinn, für das Gelingen der Online-Suche besonders wichtig ist. Die dabei inhaltlich und formal wesentlichen Aspekte können in Form praktischer Gebrauchsanweisungen aufgelistet werden. Weiter sind Interview-Stil und -Verhalten von Bedeutung; auftretende Kommunikationsbarrieren können durch Einsatz nichtverbaler Kommunikationstechniken und einfühlsames Beraterverhalten überwunden werden. Eine neue Variante des Auskunftsinterviews ist das sog. 'Presearch-Counseling', das bei der Beratung von Bibliotheksbenutzern, die endbenutzergerechte Online-Retrievalsysteme verwenden, erforderlich sind
