1. A computer-implemented method, comprising:
- storing, in a computing apparatus, a route dictionary containing a plurality of route words identifying a plurality of routes previously traversed by a user, wherein each respective route word in the route dictionary includes an ordered sequence of symbols, each of the symbols identifying a predetermined vertex in the plurality of routes previously traversed by a user;
storing, in the computing apparatus, term frequency data of the route words of the user based on frequencies with which the user has traversed respective routes represented by the route words;
communicating, by the computing apparatus with a user device, to identify one or more vertices of a route currently being traversed by the user based on GPS data from the user device;
generating, by the computing apparatus, a partial route word from a starting sequence of symbols representing the one or more vertices respectively;
while the user is currently traversing the route, predicting, using a text prediction technique for predicting from a given partial word a complete word in a dictionary according to term frequency, a particular route word in the route dictionary containing the partial route word;
identifying, by the computing apparatus, a remaining sequence of symbols that follows the starting sequence of symbols in the particular route word;
predicting, by the computing apparatus, a remaining portion of the route that is currently being traversed by the user as being identified by a set of vertices corresponding to the remaining sequence of symbols in the particular route word;
identifying, by the computing apparatus, a message based on the remaining portion of the route; and
transmitting, by the computing apparatus to the user device, the message before the user completes the predicted, remaining portion of the route.

Abstract
Predicting the future location of a user based on predicting the route that the user might take is disclosed. The routes used by the user in the past are indexed to generate a dictionary of routes which can be further augmented with contextual data. The prior routes are encoded within the dictionary such that each term representing a respective one of the prior routes comprises a collection of unique identifiers wherein each of the unique identifiers represents a segment of the respective one of the prior routes. Techniques of text prediction, term frequency for dictionary scores and other language processing techniques are used to predict the further route of the user.
