Abstract
Mittels professioneller Suchtechniken lässt sich die Recherche im WWW wesentlich schneller und zuverlässiger gestalten. Selbst eine universelle Suchmaschine, wie Google, erlaubt mittels spezieller Suchfunktionen qualifizierte Recherchen über den Freitext hinaus. Von besonderer Bedeutung sind hier die Selektion nach Domainnamen und die Einbeziehung der URL. In Kombination mit dem Verständnis der Ranking-Techniken, z. B. der Prioritäten der im HTML-Quelltext verankerten inhaltlichen Meta-Informationen (Title-Tag, Meta-Tags Keywords, Description) gegenüber dem Standardverfahren (Google PageRank) lässt sich die Recherche auf professionelle Informationsangebote ausrichten. Eine weitere Qualifizierung lässt sich durch geschickten Einsatz der Phrasensuche erreichen. In jedem Fall setzt eine erfolgreiche Recherche, auch bei scheinbar einfachen Benennungen und Zusammenhängen eine intellektuelle Recherchevorbereitung voraus - bei der zunächst das Thema strukturiert und dann eine Vorstellung über die möglichen Zusammenhänge entwickelt wird, in der die Zielinformation im WWW zu finden sein könnte. Soweit die Möglichkeit besteht, sollte bei anspruchsvollen technischwissenschaftlichen Themen der WWW-Suche eine Recherche in professionellen Literaturdatenbanken vorausgehen. Diese haben den Vorzug, dass eine transparente und sorgfältig selektierte Quellenbasis vorliegt und durch Suche mit kontrolliertem Wortschatz die typischen Unschärfen einer Freitextrecherche (unerwünschte Zusammenhänge, Synonyme, Homonyme, Schreibvarianten usw.) umgangen werden können. Die FIZ-Technik-Inform GmbH bietet kostenpflichtige Weiterbildungsveranstaltungen auch zur WWW-Recherche an.
