A system and method for predicting a future location of a user are provided. In general, a prediction basis including crowd data describing crowds in which a user was included during a number of reoccurring time windows is generated. Each reoccurring time window may be, for example, a day of the week (i.e., Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday), a portion of a day of the week (e.g., Monday Morning, Monday Afternoon, Monday Evening, Tuesday Evening, etc.), a day of the month (e.g., 1st day of the month), a day of the year (e.g., March 25th), or the like. The prediction basis of the user is then used to predict one or more future locations of the user.

The method of claim 1 wherein the crowd data describing the crowds in which the user was previously included comprises one or more crowd characteristics of each of the crowds. 7. The method of claim 6 wherein the one or more crowd characteristics of each of the crowds comprises at least one of a group consisting of: a best-case average Degree of Separation (DOS) for the crowd, a worst-case average DOS for the crowd, a degree of fragmentation of the crowd, a degree of bidirectionality of relationships of the crowd. 8.

The method of claim 1 wherein the relevant crowd data from the prediction basis is crowd data from the prediction basis for a one of the plurality of reoccurring time windows corresponding to a current time. 10. The method of claim 1 wherein the relevant crowd data from the prediction basis is crowd data from the prediction basis for a one of the plurality of reoccurring time windows immediately following a one of the plurality of reoccurring time windows corresponding to a current time. 11. The method of claim 1 wherein predicting the one or more future locations of the user based on the prediction basis further comprising, if the user is likely to move: generating expected crowd criteria describing a type of a crowd in which the user is expected to be included based on the relevant crowd data from the prediction basis;obtaining locations matching the expected crowd criteria; andproviding one or more of the locations matching the expected crowd criteria as the one or more future locations of the user. 12. The method of claim 11 wherein generating the expected crowd criteria describing the type of crowd in which the user is expected to be included comprises generating the expected crowd criteria based on all of the relevant crowd data from the prediction basis. 13. The method of claim 11 wherein the relevant crowd data comprises crowd data for a plurality of instances of one of the plurality of reoccurring time windows, and generating the expected crowd criteria describing the type of crowd in which the user is expected to be included comprises: identifying one or more patterns in the crowd data for the plurality of instances of the one of the plurality of reoccurring time windows;identifying an applicable pattern from the one or more patterns; andgenerating the expected crowd criteria based on the crowd data for a subset of the plurality of instances of the one of the plurality of reoccurring time windows that are in the applicable pattern. 14. The method of claim 11 wherein the expected crowd criteria comprises a particular combination of values for a plurality of crowd data components. 15. The method of claim 11 wherein the expected crowd criteria comprises a range of values for each of at least one of a plurality of crowd data components. 16. The method of claim 11 wherein the locations matching the expected crowd criteria comprise one or more Points of Interest (POIs) at which crowds that match the expected crowd criteria to at least a threshold degree are currently located. 17. The method of claim 11 wherein the locations matching the expected crowd criteria comprise one or more Points of Interest (POIs) at which crowds that match the expected crowd criteria to at least a threshold degree are expected to be located at a future time. 18. The method of claim 11 wherein the locations matching the expected crowd criteria comprise a location of a crowd that currently matches the expected crowd criteria to at least a threshold degree. 19. The method of claim 11 wherein the locations matching the expected crowd criteria comprise a location of a crowd that is expected to match the expected crowd criteria to at least a threshold degree at a future time. 20. The method of claim 1 wherein determining whether the user is likely to move comprises determining whether the user is likely to move based on a comparison of the current crowd data and all of the relevant crowd data from the prediction basis. 21. The method of claim 1 wherein the relevant crowd data comprises crowd data for a plurality of instances of one of the plurality of reoccurring time windows, and determining whether the user is likely to move comprises: identifying one or more patterns in the crowd data for the plurality of instances of the one of the plurality of reoccurring time windows;identifying an applicable pattern from the one or more patterns; anddetermining whether the user is likely to move based on a comparison of the current crowd data and a subset of the plurality of instances of the one of the plurality of reoccurring time windows that are in the applicable pattern. 22.
