Opinion Mining
(2010)
Das Opinion Mining stellt eine Methode dar, mit der Meinungen aus dem WWW gefiltert und intelligent aufbereitet werden können, um Stimmungsanalysen zu einzelnen Produkten und Dienstleistungen zu erstellen. Opionion Mining bietet den Unternehmen somit eine innovative Möglichkeit, ihre Marketingkommmunikation planbarer und wirkungsvoller zu gestalten und ein deutlich erhöhtes Maß an Involvement und Relevanz innerhalb bestimmter Zielgruppen zu erreichen. Zunächst werden die theoretischen Grundlagen des Web 2.0 und relevanter Methoden der Business Intelligence erläutert. Die empirische Untersuchung bildet den Schwerpunkt der Arbeit. Auf die Entwicklung eines Vorgehensmodells folgt die praktische Anwendung dieses Modells auf ein Produkt. Die Ergebnisse werden im Review-Scan im Hinblick auf Forschung und Praxis ausgewertet und diskutiert.
