Abstract

[In this chapter, we describe research in which the influence of providing feedback on the semantic relevance of queries and search results is examined with younger and older adults when they reformulate their search queries. Providing feedback on the semantic relevance of search queries and search results increased the semantic relevance of future search queries as they reformulated both for younger and older adults. This applies especially to more difficult search problems. For younger adults, in addition to the semantic relevance of search queries, also an improvement in their search performance (in terms of the amount of time and the number of clicks needed to solve the task) was observed. No such difference in search performance was found for older adults. A possible explanation could be that, older adults need more time to adjust to the new search interface in order to find effects not only in the semantic relevance of queries but also in their search performance.]
