    Abstract
    Seit Sommer 2000 betreibt das Zentrum für Psychologische Information und Dokumentation (ZPID) den PsychSpider, eine Spezialsuchmaschine für wissenschaftliche Inhalte zur Psychologie. Der PsychSpider ist vorwiegend eine Websuchmaschine, aber auch strukturierte bibliographische Daten werden indiziert. Gegenwärtig bietet der PsychSpider den integrierten Zugang zu ca. 800.000 Dokumenten aus dem Surface Web und dem Deep Web. Die Suchmaschine verfügt über zahlreiche fortschrittliche Merkmale wie Boolesche Operatoren, natürlichsprachige Eingaben, "Query-by-Example", Relevanzbewertung der Resultate, Strukturierung des Datenbestands in unterschiedliche Kollektionen, im- und exportierbare Indexe, parametrische Suche und automatische Kategorisierung. Die mehrjährige Erfahrung zeigt, dass auch eine Technologie, die eigentlich dazu dienen sollte, möglichst automatisch die relevanten Informationen aus den Myriaden von Dokumenten im Internet herauszufischen, umfängliche menschliche Betreuung braucht. Das liegt an der formalen und inhaltlichen Qualität von Inhalten, aber auch an technologischen Faktoren wie zum Beispiel Content Management Systemen. Die Nutzung des PsychSpider ist über die Jahre kontinuierlich gewachsen und er gehört zu den erfolgreichsten Web-Angeboten des ZPID. Aus strategischer Sicht ist eine nach den Kriterien einer wissenschaftlichen Fachinformationseinrichtung betriebene Suchmaschine unverzichtbar und der weitere Ausbau wird die Attraktivität deutlich erhöhen.
