ABSTRACT
A model of user-search-engine interaction is developed using the ACT-R cognitive architecture. We test, using an empirical evaluation, the model across different result orderings and relevance distributions, demonstrating that across a number of trials, the model approximates the characteristics of large numbers of users interacting with search-engines. These results are discussed in terms of their practical implications for search interfaces and ranking algorithms.

Predictive modeling of first-click behavior in web-search
WWW '06: Proceedings of the 15th international conference on World Wide WebSearch engine results are usually presented in some form of text summary (e.g., document title, some snippets of the page's content, a URL, etc). Based on the information contained within these summaries users make relevance judgments about what links ...
Using Information Foraging Theory to Understand Search Behavior in Different Environments
CHIIR '17: Proceedings of the 2017 Conference on Conference Human Information Interaction and RetrievalThe aim of this research proposal is to understand the extent in which Information Scent, part of Information Foraging Theory, influence the perception of relevance of retrieved search engine result pages (SERPs) in different environments (desktop and ...
Web searcher interaction with the Dogpile.com metasearch engine
Metasearch engines are an intuitive method for improving the performance of Web search by increasing coverage, returning large numbers of results with a focus on relevance, and presenting alternative views of information needs. However, the use of ...
