- Abstract
- Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

- Abstract
- Suchmaschinen im World Wide Web wird nachgesagt, dass sie - insbesondere im Vergleich zur Retrievalsoftware kommerzieller Online-Archive suboptimale Methoden und Werkzeuge einsetzen. Elaborierte befehlsorientierte Retrievalsysteme sind vom Laien gar nicht und vom Professional nur dann zu bedienen, wenn man stets damit arbeitet. Die Suchsysteme einiger "independents", also isolierter Informationsproduzenten im Internet, zeichnen sich durch einen Minimalismus aus, der an den Befehlsumfang anfangs der 70er Jahre erinnert. Retrievalsoftware in Intranets, wenn sie denn überhaupt benutzt wird, setzt fast ausnahmslos auf automatische Methoden von Indexierung und Retrieval und ignoriert dabei nahezu vollständig dokumentarisches Know how. Suchmaschinen bzw. Retrievalsysteme - wir wollen beide Bezeichnungen synonym verwenden - bereiten demnach, egal wo sie vorkommen, Schwierigkeiten. An ihrer Qualität wird gezweifelt. Aber was heißt überhaupt: Qualität von Suchmaschinen? Was zeichnet ein gutes Retrievalsystem aus? Und was fehlt einem schlechten? Wir wollen eine Liste von Kriterien entwickeln, die für gutes Suchen (und Finden!) wesentlich sind. Es geht also ausschließlich um Quantität und Qualität der Suchoptionen, nicht um weitere Leistungsindikatoren wie Geschwindigkeit oder ergonomische Benutzerschnittstellen. Stillschweigend vorausgesetzt wirdjedoch der Abschied von ausschließlich befehlsorientierten Systemen, d.h. wir unterstellen Bildschirmgestaltungen, die die Befehle intuitiv einleuchtend darstellen. Unsere Checkliste enthält nur solche Optionen, die entweder (bei irgendwelchen Systemen) schon im Einsatz sind (und wiederholt damit zum Teil Altbekanntes) oder deren technische Realisierungsmöglichkeit bereits in experimentellen Umgebungen aufgezeigt worden ist. insofern ist die Liste eine Minimalforderung an Retrievalsysteme, die durchaus erweiterungsfähig ist. Gegliedert wird der Kriterienkatalog nach (1.) den Basisfunktionen zur Suche singulärer Datensätze, (2.) den informetrischen Funktionen zur Charakterisierunggewisser Nachweismengen sowie (3.) den Kriterien zur Mächtigkeit automatischer Indexierung und natürlichsprachiger Suche

- Abstract
- Das Internet mit seinen ständig neuen Usern und seinem extremen Wachstum bringt viele neue Herausforderungen mit sich. Aufgrund dieses Wachstums bedienen sich die meisten Leute der Hilfe von Suchmaschinen um Inhalte innerhalb des Internet zu finden. Suchmaschinen nutzen für die Beantwortung der User-Anfragen Information Retrieval Techniken. Problematisch ist nur, dass traditionelle Information Retrieval (IR) Systeme für eine relativ kleine und zusammenhängende Sammlung von Dokumenten entwickelt wurden. Das Internet hingegen unterliegt einem ständigen Wachstum, schnellen Änderungsraten und es ist über geographisch verteilte Computer verteilt. Aufgrund dieser Tatsachen müssen die alten Techniken erweitert oder sogar neue IRTechniken entwickelt werden. Eine Suchmaschine die diesen Herausforderungen vergleichsweise erfolgreich entgegnet ist Google. Ziel dieser Arbeit ist es aufzuzeigen, wie Suchmaschinen funktionieren. Der Fokus liegt dabei auf der Suchmaschine Google. Kapitel 2 wird sich zuerst mit dem Aufbau von Suchmaschinen im Allgemeinen beschäftigen, wodurch ein grundlegendes Verständnis für die einzelnen Komponenten geschaffen werden soll. Im zweiten Teil des Kapitels wird darauf aufbauend ein Überblick über die Architektur von Google gegeben. Kapitel 3 und 4 dienen dazu, näher auf die beiden Komponenten Crawler und Indexer einzugehen, bei denen es sich um zentrale Elemente im Rahmen von Suchmaschinen handelt.
