Annotating personalized recommendations

A computer-readable medium bearing computer executable instructions which, when executed on a computer system having at least a processor and a memory, carry out a method for responding to a search query with annotated entities, comprising the method of:

• obtaining a set of search results information from a search results retrieval component responsive to receiving a search query from a computer user;
• identifying a plurality of recommended entities within the search results information and obtaining a corresponding plurality of annotations corresponding to each of the plurality of recommended entities from an annotation component and assigning an affinity value to each of the plurality of annotations, the annotation component being distinct from the search results retrieval component, wherein each annotation for each recommended entity comprises a set of annotation relationships between the user and the recommended entity, each annotation relationship describing a basis for which the recommended entity is relevant to the user, and wherein the affinity values between the user and a recommended entity are determined according to one or more probability density functions;
• selecting a threshold number of annotation relationships of the plurality of annotations having the highest affinity value between the user and the corresponding recommended entity;
• generating a search results page, wherein the generated search results page includes a portion of the search results information including at least one of the recommended entities and, for each of the recommended entities in the search results page, annotating the recommended entity by a user actionable indicator proximate to the recommended entity, wherein the user actionable indicator is configured to provide the annotation comprising the selected threshold number of annotation relationships corresponding to the recommended entity upon activation;
• and
• returning the generated search results page responsive to the search query from the user.

An annotation system for providing a plurality of annotations for a corresponding set of entities with regard to a user, wherein the annotation system is implemented on a computer system comprising at least a processor executing instructions stored in a memory, and further comprising:

• a communication component that receives a plurality of entities to annotate and the identity of a user, and that provides annotations in response to receiving the plurality of entities;
• an annotation store, the annotation store storing relationship information regarding a plurality of entities and the user;
• an annotation component that, for each entity of the set entities, provides an annotation for the entity based on the relationship information in the annotation store, and further assigns an affinity value to each of the plurality of annotations, wherein the affinity values are determined according to one or more probability density functions, and wherein each annotation for each of the plurality entities comprises a set of annotation relationships between the user and the entity, each annotation relationship describing a basis for which the entity is relevant to the user;
• and
• wherein, for each entity in the set of entities, the annotation component identifies a plurality of annotation relationships between the entity and the user, and for each annotation, includes only a threshold number of relationships having the highest affinity value between the entity and the user.
