- providing statistical information about relationships between a plurality of landmarks, the statistical information derived at least in part from records of taxi trips originating, ending, or both originating and ending at landmarks of the plurality of landmarks;
receiving a request for a search of landmarks matching a set of search criteria;
in response to the request, retrieving a set of landmarks matching the search criteria; and
, ranking the set of landmarks retrieved by the search at least in part on the basis of the statistical information.

Abstract
An example information system contains records of landmarks. The system obtains records of taxi trips between the landmarks and from the taxi trip information derives statistical relationships between the landmarks. A user can provide context information, such as an address or a type of activity. The user can then search the system for landmarks of interest to the user. The system retrieves and presents the user with a set of landmarks which match the user'"'"'s query based in part on the statistical relationships.
