    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.

    Abstract
    Searching for multimedia is an important activity for users of Web search engines. Studying user's interactions with Web search engine multimedia buttons, including image, audio, and video, is important for the development of multimedia Web search systems. This article provides results from a Weblog analysis study of multimedia Web searching by Dogpile users in 2006. The study analyzes the (a) duration, size, and structure of Web search queries and sessions; (b) user demographics; (c) most popular multimedia Web searching terms; and (d) use of advanced Web search techniques including Boolean and natural language. The current study findings are compared with results from previous multimedia Web searching studies. The key findings are: (a) Since 1997, image search consistently is the dominant media type searched followed by audio and video; (b) multimedia search duration is still short (>50% of searching episodes are <1 min), using few search terms; (c) many multimedia searches are for information about people, especially in audio search; and (d) multimedia search has begun to shift from entertainment to other categories such as medical, sports, and technology (based on the most repeated terms). Implications for design of Web multimedia search engines are discussed.

    Abstract
    We present the first systematic study of the influence of time on user judgements for rankings and relevance grades of web search engine results. The goal of this study is to evaluate the change in user assessment of search results and explore how users' judgements change. To this end, we conducted a large-scale user study with 86 participants who evaluated 2 different queries and 4 diverse result sets twice with an interval of 2 months. To analyze the results we investigate whether 2 types of patterns of user behavior from the theory of categorical thinking hold for the case of evaluation of search results: (a) coarseness and (b) locality. To quantify these patterns we devised 2 new measures of change in user judgements and distinguish between local (when users swap between close ranks and relevance values) and nonlocal changes. Two types of judgements were considered in this study: (a) relevance on a 4-point scale, and (b) ranking on a 10-point scale without ties. We found that users tend to change their judgements of the results over time in about 50% of cases for relevance and in 85% of cases for ranking. However, the majority of these changes were local.
