characterizing the first user and the second user with regard to each of a plurality of attributes, based upon the interaction information for the first user and the second user;
calculating a level of similarity of the first user and the second user, using the characterization of the first user and the characterization of the second user with regard to the plurality of attributes;
presenting to the first user a recommendation of a product or a service, based upon the similarity level and the interaction information for the first user and the second user;
after presenting the recommendation of the product or the service, providing, to the first user, a user profile of the second user so that reasons for the similarity can be reviewed by the first user;
causing, when the user profile is displayed, a list of categories and their respective similarity levels to be presented when one or more graphical elements of a graphical user interface are selected; and
causing to be presented how one or more of the similarity levels are calculated when the one or more graphical elements of the graphical user interface are selected.
2. The methods according to claim 1 , wherein the computer network comprises an e-commerce system.
3. The method according to claim 1 , wherein the interaction information is derived from social network activities of the first user and the second user over the computer network, or wherein the interaction information is derived from implicit interactions.
4. The method according to claim 1 , wherein calculating the level of similarity of the first user and the second user comprises calculating an aggregated similarity level based on user interests and product preferences, and wherein presenting the recommendation to the first user comprises displaying an indication of the level of similarity of a first attribute weight vector and a second attribute weight vector.
5. The method according to claim 4 , wherein implicit interactions comprise an addition of an item to a private catalog.
6. The method according to claim 1 , wherein calculating the level of similarity of the first user and the second user comprises calculating the aggregated similarity level using users' answers to online surveys.
7. The method according to claim 1 , wherein calculating the level of similarity of the first user and the second user comprises correcting the plurality of weights for each of the first user and the second user based upon the number of distinct users associated with each attribute.
8. A non-transitory computer-readable medium having stored thereon a plurality of code sections, each code section comprising a plurality of instructions executable by a processor to cause the processor to perform a method of producing a recommendation for a first user using interaction information for each of the first user and a second user of a plurality of users of a computer network, the interaction information for the first user and the second user being derived from interactions of the first user and the second user with the computer network, the method comprising:
characterizing the first user and the second user with regard to each of a plurality of attributes, based upon the interaction information for the first user and the second user;
calculating a level of similarity of the first user and the second user, using the characterization of the first user and the characterization of the second user with regard to the plurality of attributes;
presenting to the first user a recommendation of a product or a service, based upon the similarity level and the interaction information for the first user and the second user;
providing, to the first user, a user profile of the second user so that reasons for the similarity can be reviewed by the first user;
causing a list of categories and their respective similarity levels to be presented when one or more graphical elements of a graphical user interface are selected; and
causing to be presented how one or more of the similarity levels are calculated when the one or more graphical elements of the graphical user interface are selected.
9. The non-transitory computer-readable medium according to claim 8 , wherein the computer network comprises an e-commerce system.
10. The non-transitory computer-readable medium according to claim 8 , wherein the interaction information is derived from social network activities of the first user and the second user over the computer network, or wherein the interaction information is derived from implicit interactions.
11. The non-transitory computer-readable medium according to claim 8 , wherein calculating the level of similarity of the first user and the second user comprises calculating an aggregated similarity level based on user interests and product preferences, and wherein presenting the recommendation to the first user comprises displaying an indication of the level of similarity of a first attribute weight vector and a second attribute weight vector.
12. The non-transitory computer-readable medium according to claim 11 , wherein implicit interactions comprise a vote on an online survey.
13. The non-transitory computer-readable medium according to claim 8 , wherein calculating the level of similarity of the first user and the second user comprises calculating the aggregated similarity level using users' answers to online surveys.
14. The non-transitory computer-readable medium according to claim 8 , wherein calculating the level of similarity of the first user and the second user comprises correcting the plurality of weights for each of the first user and the second user based upon the number of distinct users associated with each attribute.
15. A system for producing a recommendation for a first user using interaction information for each of the first user and a second user of a plurality of users of a computer network, the interaction information for the first user and the second user being derived from interactions of the first user and the second user with the computer network, the system comprising:
at least one processor for communicatively coupling to the first user and the second user, the at least one processor operable to, at least:
characterize the first user and the second user with regard to each of a plurality of attributes, based upon the interaction information for the first user and the second user;
calculate a level of similarity of the first user and the second user, using the characterization of the first user and the characterization of the second user with regard to the plurality of attributes;
present to the first user a recommendation of a product or a service, based upon the similarity level and the interaction information for the first user and the second user; and
provide, to the first user, a user profile of the second user so that reasons for the similarity can be reviewed by the first user;
cause a list of categories and their respective similarity levels to be presented when one or more graphical elements of a graphical user interface are selected; and
cause to be presented how one or more of the similarity levels are calculated when the one or more graphical elements of the graphical user interface are selected.
16. The system according to claim 15 , wherein the computer network comprises an e-commerce system.
17. The system according to claim 15 , wherein the interaction information is derived from social networking activities of the first user and the second user over the computer network, or wherein the interaction information is derived from implicit interactions.
