Ambiguity and Clarification

By the time web engines were developed, the number of queries prompted by users had grown exponentially. This fast growth shows the high demand of users from web search engines. This high demand made search engines responsible for the users' satisfaction during a search session. One way to improve a user's satisfaction is to visualize search engine result page (SERP). Recent studies for meeting this aim focused on a whole page thumbnail for assisting users to remember recently visited web pages. This chapter explores how a specific visual content of a page can allow users to distinguish between a useful and worthless page within results in SERP especially in an ambiguous search task.
