26. A system for generating a profile vector in a computer environment, comprising: a converter capable of converting a plurality of observed behaviors of a user into an associated plurality of behavior vectors; and a profile adapter capable of repeatedly modifying a profile vector indicative of the user based on the plurality of behavior vectors.

The system as defined in claim 26, wherein the profile adapter includes modifies the profile vector based upon at least one parameter selected from the group consisting of: a threshold by which a behavior vector will be used instead of the profile vector, a learning rate for a profile update, a learning rate for an entity update, an update rate for a query universe estimate of a mean, an update for a profile universe update of a mean, a forgetting factor for a set of profile vectors, a forgetting factor for a set of entity vectors, a mean of a set of entity vectors, a mean of a set profile vectors, and a mean of a set of behavior vectors.
