Abstract. This paper shows how technologies for Web data extraction, syndication and integration allow for new applications and services in the Business Intelligence and the Semantic Web domain. First, we demonstrate how knowledge about market developments and competitor activities on the market can be extracted dynamically and automatically from semi-structured information sources on the Web. Then, we show how the data can be integrated in Business Intelligence Systems and how data can be classified, re-assigned and transformed with the aid of Semantic Web ontological domain knowledge. Existing Semantic Web and Business Intelligence applications and scenarios using our technology illustrate the whole process.
The World Wide Web is the largest database on earth -a huge amount of data and information primarily intended for human users. Unfortunately, data on the web requires intelligent interpretation and cannot be easily used by programs. It requires advanced data extraction and information integration techniques to automatically process data. Lixto technology addresses these issues and enables developers to interactively turn web pages into mobile services.Keywords: web data extraction; intelligent data integration; mobile data services 1, Einf~hrung
Entwicklungen am MobilfunkmarktDie vom Ende der Dotcom-Euphorie negativ beeinflusste Mobilfunkbranche kann wieder deutliche Zuw&chse aufweisen. Gartner Group bescheinigt der Branche sogar ,,das Potential, die technologische Innovation im luK-Bereich innerhalb der n&chs-ten 5 Jahre mit anzuf~hren" (Desai etaL, 2004 (Desai et aL, 2004, Burden et aL, 2004.Bei den mobilen Datendiensten konnten Servicequalit&t, Verfegbarkeit und Geschwindigkeit innerhalb der letzten Jahre stark verbessert werden: Lag die maximale DatenQbertragungsrate bei GSM noch bei max. 14,4 kBit/s, ist sie bei GPRS bei 54,6 kBit/s und erreicht bei UMTS bis zu 2 MBit/s (Stiehler, Wichmann, 2004 (Spiess, 2004). So rechnen laut einer neuen Umfrage 75 % der deutschen CP mit einem deutlichen Umsatzplus for dieses Jahr (Bitkom, 2004
