Abstract

Im Zuge der immer größeren Verfügbarkeit von Daten (Big Data) und rasanter Fortschritte im Daten-basierten maschinellen Lernen haben wir in den letzten Jahren Durchbrüche in der künstlichen Intelligenz erlebt. Dieser Vortrag beleuchtet diese Entwicklungen insbesondere im Hinblick auf die automatische Analyse von Textdaten. Anhand einfacher Beispiele illustrieren wir, wie moderne Textanalyse abläuft und zeigen wiederum anhand von Beispielen, welche praktischen Anwendungsmöglichkeiten sich heutzutage in Branchen wie dem Verlagswesen, der Finanzindustrie oder dem Consulting ergeben.

Abstract

Die Idee zu einem semantischen Web wurde maßgeblich geprägt (wenn auch nicht initiiert) durch eine Veröffentlichung von Tim Berners Lee, James Hendler und Ora Lassila im Jahre 2001. Darin skizzieren die Autoren ihre Version von einem erweiterten und verbesserten World Wide Web: Daten sollen so aufbereitet werden, dass nicht nur Menschen diese lesen können, sondern dass auch Computer in die Lage versetzt werden, diese zu verarbeiten und sinnvoll zu kombinieren. Sie beschreiben ein Szenario, in dem "Web agents" dem Nutzer bei der Durchführung komplexer Suchanfragen helfen, wie beispielsweise "finde einen Arzt, der eine bestimmte Behandlung anbietet, dessen Praxis in der Nähe meiner Wohnung liegt und dessen Öffnungszeiten mit meinem Terminkalender zusammenpassen". Die große Herausforderung liegt hierbei darin, dass Informationen, die über mehrere Webseiten verteilt sind, gesammelt und zu einer sinnvollen Antwort kombiniert werden müssen. Man spricht dabei vom Problem der Informationsintegration (Information Integration). Diese Vision der weltweiten Datenintegration in einem Semantic Web wurde seither vielfach diskutiert, erweitert und modifiziert, an der technischen Realisation arbeitet eine Vielzahl verschiedener Forschungseinrichtungen. Einigkeit besteht dahingehend, dass eine solche Idee nur mit der Hilfe neuer bedeutungstragender Metadaten verwirklicht werden kann. Benötigt werden also neue Ansätze zur Indexierung von Web Inhalten, die eine Suche über Wortbedeutungen und nicht über bloße Zeichenketten ermöglichen können. So soll z.B. erkannt werden, dass es sich bei "Heinrich Heine" um den Namen einer Person handelt und bei "Düsseldorf" um den Namen einer Stadt. Darüber hinaus sollen auch Verbindungen zwischen einzelnen Informationseinheiten festgehalten werden, beispielsweise dass Heinrich Heine in Düsseldorf wohnte. Wenn solche semantischen Relationen konsequent eingesetzt werden, können sie in vielen Fällen ausgenutzt werden, um neue Schlussfolgerungen zu ziehen.
