- Abstract
- In unserem Retrievaltest von Suchwerkzeugen im World Wide Web (Password 11/2000) schnitt die Suchmaschine Google am besten ab. Im Vergleich zu anderen Search Engines setzt Google kaum auf Informationslinguistik, sondern auf Algorithmen, die sich aus den Besonderheiten der Web-Dokumente ableiten lassen. Kernstück der informationsstatistischen Technik ist das "PageRank"- Verfahren (benannt nach dem Entwickler Larry Page), das aus der Hypertextstruktur des Web die "Popularität" von Seiten anhand ihrer ein- und ausgehenden Links berechnet. Google besticht durch das Angebot intuitiv verstehbarer Suchbildschirme sowie durch einige sehr nützliche "Kleinigkeiten" wie die Angabe des Rangs einer Seite, Highlighting, Suchen in der Seite, Suchen innerhalb eines Suchergebnisses usw., alles verstaut in einer eigenen Befehlsleiste innerhalb des Browsers. Ähnlich wie RealNames bietet Google mit dem Produkt "AdWords" den Aufkauf von Suchtermen an. Nach einer Reihe von nunmehr vier Password-Artikeln über InternetSuchwerkzeugen im Vergleich wollen wir abschließend zu einer Bewertung kommen. Wie ist der Stand der Technik bei Directories und Search Engines aus informationswissenschaftlicher Sicht einzuschätzen? Werden die "typischen" Internetnutzer, die ja in der Regel keine Information Professionals sind, adäquat bedient? Und können auch Informationsfachleute von den Suchwerkzeugen profitieren?

- Abstract
- Web Search Engines und Web Directories sind die technologische Speerspitze im High-Tech-Bereich Internet. Als Suchassistenten gestatten sie Laien und Profi-Searchern gleichsam einen optimalen Einstieg in die Vielfalt der Informationsquellen des World Wide Web, Sie ermöglichen durch eine Kombination aus hierarchisch geordnetem kontrollierten Vokabular, automatischer Indexierung sowie diverser Synonym-, Homonym- und Fachwörterbücher einen zielgenauen Zugriff auf WebSites. - Stop! Glauben Sie das? Wir waren skeptisch und haben Suchmaschinen und Suchverzeichnisse genau angeschaut. Durchgeführt wurde ein Retrievaltest, der unterschiedliche Suchsysteme mit jeweils dergleichen Anfrage konfrontierte, auf die wir bereits die Antwort wussten ("Known Item Search"). Skizziert werden zudem bisher ausgearbeitete empirische Erhebungen zur Evaluation von Web-Retrievalsystemen, angefangen von seriösen informationswissenschaftlichen Forschungen bis hinzu den Tests in Publikumszeitschriften
