    Abstract
    Jean Tague-Sutcliffe was an important figure in information retrieval experimentation. Here, she reviews the history of IR research, and provides a description of the fundamental paradigm of information retrieval experimentation that continues to dominate the field.

    Abstract
    This paper presents a set of basic components which constitutes the experimental setting intended for the evaluation of interactive information retrieval (IIR) systems, the aim of which is to facilitate evaluation of IIR systems in a way which is as close as possible to realistic IR processes. The experimental settings consists of 3 components: (1) the involvement of potential users as test persons; (2) the application of dynamic and individual information needs; and (3) the use of multidimensionsal and dynamic relevance judgements. Hidden under the information need component is the essential central sub-component, the simulated work task situation, the tool that triggers the (simulated) dynamic information need. This paper also reports on the empirical findings of the meta-evaluation of the application of this sub-component, the purpose of which is to discover whether the application of simulated work task situations to future evaluation of IIR systems can be recommended. Investigations are carried out to dertermine whether any search behavioural differences exist between test persons' treatment of their own real information needs versus simulated information needs. The hypothesis is that if no difference exist one can correctly substitute real information needs with simulated information needs through the application of simulated work task situations. The empirical results of the meta-evaluation provide positive evidence for the application of simulated work task situations to the evaluation of IIR systems. The results also indicate that tailoring work task situations to the group of test persons is important in motivating them. Furthermore, the results of the evaluation show that different versions of semantic openness of the simulated situations make no difference to the test persons' search treatment

    Abstract
    Searching for information on the WWW basically comes down to locating an appropriate Web site and to retrieving relevant information from that site. This study examined the effect of a user's WWW experience on both phases of the search process. 35 students from 2 schools for Dutch pre-university education were observed while performing 3 search tasks. The results indicate that subjects with WWW-experience are more proficient in locating Web sites than are novice WWW-users. The observed differences were ascribed to the experts' superior skills in operating Web search engines. However, on tasks that required subjects to locate information on specific Web sites, the performance of experienced and novice users was equivalent - a result that is in line with hypertext research. Based on these findings, implications for training and supporting students in searching for information on the WWW are identified. Finally, the role of the subjects' level of domain expertise is discussed and directions for future research are proposed

    Abstract
    Folgender Beitrag beschäftigt sich mit der Konzeption und Durchführung von nachhaltigen Evaluationen von Information Retrieval Systemen mit Visualisierungskomponenten. Bisherige Evaluationsansätze differieren sowohl in der Methodenauswahl als auch Untersuchungsanlage, wie eine State-of-the-Art-Analyse aufzeigt. Im Anschluss werden die größten Herausforderungen, die sich bei Evaluationen dieser Art ergeben mit Vorschlägen zu potenziellen Lösungsansätzen diskutiert. Auf der Grundlage eines morphologischen Rahmens wird ein Bezugsrahmen für die Evaluation von Information Retrieval Systemen mit Visualisierungskomponenten vorgeschlagen, das einen integrierten Ansatz zur Kombination geeigneter Methoden aus dem Bereich der Usability-Evaluation und der Retrievaleffektivitäts-Evaluation verfolgt.
