    Abstract
    The suggestion that classifications for retrieval should be constructed automatically raises some serious problems concerning the sorts of classification which are required, and the way in which formal classification theories should be exploited, given that a retrieval classification is required for a purpose. These difficulties have not been sufficiently considered, and the paper therefore attempts an analysis of them, though no solution of immediate application can be suggested. Starting with the illustrative proposition that a polythetic, multiple, unordered classification is required in automatic thesaurus construction, this is considered in the context of classification in general, where eight sorts of classification can be distinguished, each covering a range of class definitions and class-finding algorithms. The problem which follows is that since there is generally no natural or best classification of a set of objects as such, the evaluation of alternative classifications requires either formal criteria of goodness of fit, or, if a classification is required for a purpose, a precises statement of that purpose. In any case a substantive theory of classification is needed, which does not exist; and since sufficiently precise specifications of retrieval requirements are also lacking, the only currently available approach to automatic classification experiments for information retrieval is to do enough of them

    Abstract
    Bruner war der erste Erforscher des Spracherwerbs von Kindern, der Wittgensteins Problem zu würdigen wußte und eine Antwort darauf vorschlug. Wittgensteins allgemeinem Ansatz folgend, behauptete Bruner, daß das Kind den konventionellen Gebrauch eines sprachlichen Symbols dadurch erwirbt, daß es lernt, an einer Interaktionsform (Lebensform, Szene gemeinsamer Aufmerksamkeit) teilzunehmen, die es zunächst nichtsprachlich versteht, so daß die Sprache des Erwachsenen in geteilten Erfahrungen verankert werden kann, deren soziale Bedeutung es schon begreift. Eine Schlüsselkomponente dieses Prozesses ist zunächst ein Kind, das Erwachsene als intentionale Wesen auffassen kann, so daß es in bestimmten Kontexten seine Aufmerksamkeit mit ihnen teilen kann. Eine andere Komponente ist jedoch die bereits existierende, äußere soziale Welt, in der das Kind lebt. Um Sprache zu erwerben, muß das Kind in einer Welt leben, die strukturierte soziale Tätigkeiten aufweist, die es verstehen kann, so wie unser hypothetischer Besucher Ungarns das Kaufen von Fahrkarten und das Reisen mit Zügen verstand. Für Kinder bedeutet das häufig die Wiederkehr derselben routinemäßigen, allgemeinen Aktivität, so daß sie erkennen können, wie diese Aktivität aufgebaut ist und wie die verschiedenen sozialen Rollen in ihr funktionieren. Wenn wir am Spracherwerb interessiert sind, muß der Erwachsene außerdem ein neues sprachliches Symbol auf eine solche Weise verwenden, die das Kind als relevant für die gemeinsame Tätigkeit erkennen kann (nämlich im Gegensatz zur unvermittelten Ansprache des Ungarn auf dem Bahnhof). Wenn ein Kind in eine Welt geboren werden würde, in der dieselbe Art von Ereignis nie wiederkehrte, derselbe Gegenstand nie zweimal erschiene und Erwachsene nie dieselben Ausdrücke im selben Kontext verwendeten, dann würde im allgemeinen schwer zu sehen sein, wie dieses Kind eine natürliche Sprache erwerben könnte, welche kognitiven Fähigkeiten es auch immer haben möge. Eine Reihe von Untersuchungen hat gezeigt, daß Kinder nach ersten Fortschritten beim Spracherwerb neue Wörter am besten in Szenen gemeinsamer Aufmerksamkeit lernen. Oft handelt es sich dabei um solche, die in ihrer täglichen Erfahrung wiederkehren, wie Baden, Füttern, Windelwechseln, Vorlesen und Autofahren. Diese Tätigkeiten sind in vielen Hinsichten analog zu dem Szenario des Fahrkartenkaufs auf einem Bahnhof, insofern das Kind seine eigenen und die Ziele des Erwachsenen in der jeweiligen Situation versteht, was ihm ermöglicht, die Relevanz des Sprachverhaltens des Erwachsenen für diese Ziele zu erschließen. So stellten Tomasello und Todd fest, daß Kinder, die mit ihren Müttern längere Zeit bei Tätigkeiten gemeinsamer Aufmerksamkeit im Alter zwischen zwölf und achtzehn Monaten verbrachten, mit achtzehn Monaten ein größeres Vokabular hatten. Bei der Sprachverwendung Erwachsener innerhalb dieser Szenen gemeinsamer Aufmerksamkeit fanden Tomasello und Farrar sowohl korrelative als auch experimentelle Belege für die Hypothese, daß Mütter, die Sprache beim Versuch verwendeten, der Aufmerksamkeit ihrer Kinder zu folgen (d. h. über einen Gegenstand zu sprechen, der schon im Brennpunkt des Interesses und der Aufmerksamkeit des Kindes stand), Kinder mit einem größeren Vokabular hatten als Mütter, die Sprache beim Versuch verwendeten, die Aufmerksamkeit des Kindes auf etwas Neues zu lenken.
