- Der Beitrag präsentiert eine Studie über Evaluationsmethoden zur WebUsability. Er beschreibt die "Heuristics for Web Communications" und berichtet von den praktischen Erfahrungen mit den Heuristiken, die mit dem "Keevil Index" verglichen und mit Benutzertests mit lautem Denken kombiniert werden. Das Ergebnis zeigt, dass eine Evaluation mit den beschriebenen Heuristiken gegenüber dem "Keevil Index" mehr Zeit und Aufwand erfordert, aber konsistentere Ergebnisse bringt. Die Heuristiken haben sich sowohl in der experten-zentrierten Evaluation als auch in Kombination mit dem Benutzertest insgesamt als geeignete Evaluationsmethode erwiesen

- Abstract
- We report a naturalistic interactive information retrieval (IIR) study of 18 ordinary users in the age of 20-25 who carry out everyday-life information seeking (ELIS) on the Internet with respect to the three types of information needs identified by Ingwersen (1986): the verificative information need (VIN), the conscious topical information need (CIN), and the muddled topical information need (MIN). The searches took place in the private homes of the users in order to ensure as realistic searching as possible. Ingwersen (1996) associates a given search behaviour to each of the three types of information needs, which are analytically deduced, but not yet empirically tested. Thus the objective of the study is to investigate whether empirical data does, or does not, conform to the predictions derived from the three types of information needs. The main conclusion is that the analytically deduced information search behaviour characteristics by Ingwersen are positively corroborated for this group of test participants who search the Internet as part of ELIS.

- Abstract
- Usability of Web sites has become an increasingly important area of research as Web sites proliferate and problems with use are noted. Generally, aspects of Web sites that have been investigated focus on such areas as overall design and navigation. The exploratory study reported on here investigates one specific component of a Web site-the index structure. By employing index usability metrics developed by Liddy and Jörgensen (1993; Jörgensen & Liddy, 1996) and modified to accommodate a hypertext environment, the study compared the effectiveness and efficiency of 20 subjects who used one existing index (the A-Z index on the FedStats Web site at http://www.fedstats.gov) and three experimental variants to complete five researcher-generated tasks. User satisfaction with the indexes was also evaluated. The findings indicate that a hypertext index with multiple access points for each concept, all linked to the same resource, led to greater effectiveness and efficiency of retrieval on almost all measures. Satisfaction measures were more variable. The study offers insight into potential improvements in the design of Web-based indexes and provides preliminary assessment of the validity of the measures employed
