Since the 1990s, the number of websites has increased extensively and online information seeking (IS) has become an integral part of our daily activities. In parallel, the population aged over 65 is increasing in all OECD countries, a trend that is expected to continue in the coming decades (OECD, 2009). Accessing the Web for older people is a very important challenge, as it helps them to foster independence, reduce isolation, and to increase communication and wellbeing. Despite its importance there is still a lack of focus on improving the use of Internet by older people. There is a clear need of detailed process models that account for age-related individual differences in information seeking.

The aims of this research project are:

(1) To interleave empirical studies with the development of new computational models of information seeking (IS) to account for age-related individual differences.

(2) To create tools to support older people while seeking information on the Web.

Firstly, the development of such a model is required for a better understanding of the IS activities and for supporting older users. To this end, the current project aims to determine the effect of cognitive processes and abilities related to fluid and crystallized intelligence on IS while considering the age of participants (old vs. young adults) and type of documents to be interacted with, during different stages of IS, i.e. from the formulation of the query with a search engine tool to the processing of and navigation through web pages. We will compare search and navigation performance and strategies of younger and older web users to the performance obtained by two complementary models of search and navigation: SNIF-ACT and CoLiDeS+Pic. Secondly, the objectives are to achieve a better understanding of cognitive difficulties experienced by older adults, and to improve our model of IS activity and on basis of that to develop tools to support this IS activity.
