Claim of US Patent No. 9,882,790

1. A method for providing recommendations of entities to be executed by at least one electronic device, the method comprising:
obtaining a first token set associated with a first entity, the first token set comprising a plurality of identifiable tokens;
adapting, at one or more processing devices, the first token set based on an interaction between the first entity and a second
entity, based on a second token set associated with the second entity, the first token set being altered to increasingly resemble
the second set, and based on the first token set, the second token set being altered to increasingly resemble the first token
set;

obtaining information, at the one or more processing devices, regarding a plurality of token sets associated with a corresponding
plurality of entities;

determining, at the one or more processing devices, an indication of similarity between the first token set and each set in
said plurality of token sets; and

based on the determined indications of similarity, establishing, at the one or more processing devices, a recommendation regarding
a sub-set of one or more entities from said plurality of entities,

wherein the first entity obtains at least part of the second token set and alters the first token set to increasingly resemble
the second token set using the obtained part of the second token set, and the second entity obtains at least part of the first
token set and alters the second token set to increasingly resemble the first token set using the obtained part of the first
token set.
