Users’ perceptions of the Web as revealed by transaction log analysis Available to Purchase

When information seekers use an information retrieval system their strategy is based, at least in part, on the perceptions they have formed about that environment. A random sample was gathered of more than 2,000 actual search queries submitted by users to one Web search engine, WebCrawler, in two separate capture sessions. The results suggest that a high proportion of users do not employ advanced search features, and those who do frequently misunderstand them. Furthermore, many users seem to have formed a model of the Web that imbues it with the intelligence found in a reference librarian, for example, but not a retrieval system. The linguistic structure of many queries resembles a typical human‐human communication model that is unlikely to produce satisfactory results in a human‐computer communication environment such as that offered currently by the Web. Design of more intuitive systems is dependent upon a more complete understanding of user behaviour at the intellectual and emotional as well as the technical levels.
