    Abstract
    Wir werden einmal die Grundlagen des Text-Mining-Systems bei IBM darstellen, dann werden wir das Projekt etwas umfangreicher und deutlicher darstellen, da kennen wir uns aus. Von daher haben wir zwei Teile, einmal Heidelberg, einmal Hamburg. Noch einmal zur Technologie. Text-Mining ist eine von IBM entwickelte Technologie, die in einer besonderen Ausformung und Programmierung für uns zusammengestellt wurde. Das Projekt hieß bei uns lange Zeit DocText Miner und heißt seit einiger Zeit auf Vorschlag von IBM DocCat, das soll eine Abkürzung für Document-Categoriser sein, sie ist ja auch nett und anschaulich. Wir fangen an mit Text-Mining, das bei IBM in Heidelberg entwickelt wurde. Die verstehen darunter das automatische Indexieren als eine Instanz, also einen Teil von Text-Mining. Probleme werden dabei gezeigt, und das Text-Mining ist eben eine Methode zur Strukturierung von und der Suche in großen Dokumentenmengen, die Extraktion von Informationen und, das ist der hohe Anspruch, von impliziten Zusammenhängen. Das letztere sei dahingestellt. IBM macht das quantitativ, empirisch, approximativ und schnell. das muss man wirklich sagen. Das Ziel, und das ist ganz wichtig für unser Projekt gewesen, ist nicht, den Text zu verstehen, sondern das Ergebnis dieser Verfahren ist, was sie auf Neudeutsch a bundle of words, a bag of words nennen, also eine Menge von bedeutungstragenden Begriffen aus einem Text zu extrahieren, aufgrund von Algorithmen, also im Wesentlichen aufgrund von Rechenoperationen. Es gibt eine ganze Menge von linguistischen Vorstudien, ein wenig Linguistik ist auch dabei, aber nicht die Grundlage der ganzen Geschichte. Was sie für uns gemacht haben, ist also die Annotierung von Pressetexten für unsere Pressedatenbank. Für diejenigen, die es noch nicht kennen: Gruner + Jahr führt eine Textdokumentation, die eine Datenbank führt, seit Anfang der 70er Jahre, da sind z.Z. etwa 6,5 Millionen Dokumente darin, davon etwas über 1 Million Volltexte ab 1993. Das Prinzip war lange Zeit, dass wir die Dokumente, die in der Datenbank gespeichert waren und sind, verschlagworten und dieses Prinzip haben wir auch dann, als der Volltext eingeführt wurde, in abgespeckter Form weitergeführt. Zu diesen 6,5 Millionen Dokumenten gehören dann eben auch ungefähr 10 Millionen Faksimileseiten, weil wir die Faksimiles auch noch standardmäßig aufheben.

    Abstract
    Die rasante technologische Entwicklung der letzten zwei Jahrzehnte ermöglicht heute die persistente Speicherung riesiger Datenmengen durch den Computer. Forscher an der Universität Berkeley haben berechnet, dass jedes Jahr ca. 1 Exabyte (= 1 Million Terabyte) Daten generiert werden - ein großer Teil davon in digitaler Form. Das bedeutet aber, dass in den nächsten drei Jahren mehr Daten generiert werden als in der gesamten menschlichen Entwicklung zuvor. Die Daten werden oft automatisch mit Hilfe von Sensoren und Überwachungssystemen aufgezeichnet. So werden beispielsweise alltägliche Vorgänge des menschlichen Lebens, wie das Bezahlen mit Kreditkarte oder die Benutzung des Telefons, durch Computer aufgezeichnet. Dabei werden gewöhnlich alle verfügbaren Parameter abgespeichert, wodurch hochdimensionale Datensätze entstehen. Die Daten werden gesammelt, da sie wertvolle Informationen enthalten, die einen Wettbewerbsvorteil bieten können. Das Finden der wertvollen Informationen in den großen Datenmengen ist aber keine leichte Aufgabe. Heutige Datenbankmanagementsysteme können nur kleine Teilmengen dieser riesigen Datenmengen darstellen. Werden die Daten zum Beispiel in textueller Form ausgegeben, können höchstens ein paar hundert Zeilen auf dem Bildschirm dargestellt werden. Bei Millionen von Datensätzen ist dies aber nur ein Tropfen auf den heißen Stein.

    Abstract
    Discusses the importance of knowledge organization in the context of the information overload caused by the vast quantities of data and information accessible on internal and external networks of an organization. Defines the characteristics of a knowledge-based product. Elaborates on the techniques and applications of text mining in developing knowledge products. Presents two approaches, as case studies, to the making of knowledge products: (1) steps and processes in the planning, designing and development of a composite multilingual multimedia CD product, with the potential international, inter-cultural end users in view, and (2) application of natural language processing software in text mining. Using a text mining software, it is possible to link concept terms from a processed text to a related thesaurus, glossary, schedules of a classification scheme, and facet structured subject representations. Concludes that the products of text mining and data mining could be made more useful if the features of a faceted scheme for subject classification are incorporated into text mining techniques and products.
