    Title: Delphic Costs and Benefits in Web Search: A utilitarian & historical analysis

    Speaker: Andrei Broder, Google

    Abstract:

    Web search engines are widely perceived as "free." But search is not effortless: in reality there are many intermingled non-monetary costs (e.g. time costs, cognitive costs, interactivity costs, etc.) and the benefits may be marred by various impairments, such as misunderstanding and misinformation. This characterization of costs and benefits appears to be inherent to the human search for information; most of the costs and impairments can be identified in interactions with any web search engine, interactions with public libraries, and even in interactions with ancient oracles. To emphasize this innate connection, we call these costs and benefits Delphic, in contrast to explicitly financial costs and benefits. Our main thesis is that users' satisfaction with a search engine mostly depends on their experience of Delphic cost and benefits, in other words on their utility. The consumer utility is correlated with classic measures of search engine quality, such as ranking, precision, recall, etc., but is not completely determined by them. To argue our thesis, we catalog the Delphic costs and benefits and show how the development of search engines over the last quarter century was driven to a large extent by the quest of decreasing Delphic costs and increasing Delphic benefits. This is joint work with Preston McAfee.
