Abstract: Systems and methods are provided to evaluate a search engine using search results retrieved from a plurality of different search engines. For example, a controller can randomly distribute a set of pre-formulated queries to a plurality of computers to query the search engines at random times to obtain search results and combine the search results to evaluate the completeness of a query result provided by a particular search engine. The controller may simulate the random queries from users using a set of computers and may reduce the burden on the search engines by spreading out the query activities over a period of time, such as a month.

Abstract: Systems and techniques for predicting customer response to content and selecting content for delivery to particular customers in accordance with the predictions. As information is delivered to and received from a plurality of customers over multiple communication channels, data streams representing communications between providers and customers are analyzed and selected data extracted therefrom. Linkages are created between data collected from the different channels and data are anonymized. The data are analyzed to create a customer response predictor for each customer that models customer behavior and predicts customer response to advertisements. As content, such as advertisements, are to be delivered to a destination, information from a predictor created using data collected from a customer associated with the destination is used to select appropriate content.
