Modeling Information Navigation: Implications for Information Architecture
Previous studies for menu and Web search tasks have suggested differing advice on the optimal number of selections per page. In this paper, we examine this discrepancy through the use of a computational model of information navigation that simulates users navigating through a Web site. By varying the quality of the link labels in our simulations, we find that the optimal structure depends on th...
متن کاملModeling an Opportunistic Strategy for Information Navigation
A computational model of a user navigating Web pages was used to identify factors that affect Web site usability. The model approximates a typical user searching for specified target information in architectures of varying menu depth. Search strategies, link ambiguity, and memory capacity were varied and model predictions compared to human user data. A good fit to observed data was obtained for...
متن کاملModeling information architecture for the organization
The issue of information architecture (IA) for organizations has recently received considerable attention in IS development. However, as yet little research has been reported on modeling IA using a systematic approach. This paper describes an objectoriented method for modeling it. The proposed method extends the traditional concept of IS analysis into the context of contemporary information tec...
متن کاملModeling Secure Navigation in Web Information Systems
Secure web information systems are becoming increasingly important due to rising cybercrime as well as the growing awareness of data privacy. Besides authentication and confidential connections, both data access control and navigational access control are the most relevant security features in this field. Adding such security features, however, to already implemented web applications is an erro...
متن کاملToward Modeling Contextual Information in Web Navigation
Existing cognitive models of web navigation mainly address the process of assessing relevance (‘information scent’) of screen objects to user’s goals. Recent research shows that users decisions are based not only on the assessed relevance of the currently available screen objects, but also on relevance of objects that were encountered in earlier steps of the navigation session. We propose the c...
