Identifying entities based on interactivity models

1. A method performed by a computing system for analyzing interactivity between a target entity and participant entities, the method comprising:

receiving indications of interactions between the target entity and participant entities;

for at least some of the participant entities, maintaining an interactivity model for the target entity and each participant entity based on the interactions between the target entity and that participant entity, the interactivity model for a participant entity including totals of interactions between the target entity and that participant entity covering multiple time frames;

receiving a query that specifies an interactivity criterion, the interactivity criterion specifying a characteristic of an interactivity model;

analyzing interactivity models to determine whether the interactivity criterion is satisfied wherein the target entity satisfies the interactivity criterion when one or more interactivity models exhibit the characteristic; and

when the interactivity criterion is satisfied, sending a response to the query indicating that the interactivity criterion is satisfied.

2. The method of claim 1 wherein the total for the most recent time frame is updated in real time as indications of interactions are received.

3. The method of claim 1 wherein the interactivity criterion specifies a characteristic of an interactivity model and wherein a participant entity satisfies the interactivity criterion when the interactivity model of the participant entity exhibits the characteristic.

4. The method of claim 3 wherein the response identifies the participant entities that satisfy the interactivity criterion.

5. The method of claim 1 wherein interactivity models are generated for multiple target entities and stored in a distributed manner.

6. The method of claim 1 wherein each interaction has an interaction type that is selected from a group consisting of an electronic mail message, a text message, an instant message, a scheduled meeting, a voice mail, a phone call, and a document collaboration.

7. A computer-readable storage medium storing computer-executable instructions for identifying an entity that satisfies an interactivity criterion, the computer-executable instructions comprising instructions that:

generate a query that specifies the interactivity criterion, the interactivity criterion specifying a characteristic of an interactivity model;

identify entities as target entities for responding to the query, a target entity having interactivity models, each interactivity model modeling interactions between the target entity and a participant entity and including totals of interactions between the target entity and that participant entity covering multiple time frames;

send a query for the identified target entities;

receive a response for the target entities, a response for a target entity indicating whether the interactivity criterion is satisfied by the target entity or one or more participant entities based on analysis of the interactivity models of the target entity, wherein a target entity satisfies the interactivity criterion when one or more interactivity models of the target entity exhibit the characteristic and a participant entity satisfies the interactivity criterion when the interactivity model for the participant entity exhibits the characteristic; and

generate query results based on the entities that satisfy the interactivity criterion as indicated by the received response.

8. The computer-readable storage medium of claim 7 wherein the instructions that identify the entities as target entities include instructions that compare a target profile to profiles of entities and select those entities with a profile that matches the target profile.

9. The computer-readable storage medium of claim 7 wherein the interactivity models of an entity are stored separately from the interactivity models of other entities such that the interactivity models of the entities are stored in a distributed manner.

10. A method performed by a computing device for tracking interactivity between entities, the method comprising:

receiving indications of interactions between a target entity and participant entities; and

upon receiving an indication of an interaction between the target entity and a participant entity, updating in real time an interactivity model for the target entity and that participant entity, each interactivity model of a participant entity modeling interactions between the target entity and the participant entity and including totals of interactions between the target entity and the participant entity covering multiple time frames

wherein the interactivity models are adapted to be analyzed to determine whether an interactivity criterion is satisfied, wherein the interactivity criterion specifies a characteristic of an interactivity model, wherein the target entity satisfies the interactivity criterion when one or more interactivity models exhibit the characteristic.

11. The method of claim 10 wherein the interactivity models for the target entity are stored at a computing device of the target entity.

12. The method of claim 10 wherein the total for the most recent time frame is updated in real time as indications of interactions are received.

13. The method of claim 10 further comprising maintaining separate interactivity models for different interaction types.

14. The method of claim 10 wherein each interaction has an interaction type that is selected from a group consisting of a scheduled meeting, a voice mail message, an electronic mail message, a text message, and a phone call.

15. A method performed by a computing system for analyzing interactivity between a target entity and participant entities, the method comprising:

receiving indications of interactions between the target entity and participant entities;

for at least some of the participant entities, maintaining an interactivity model for the target entity and each participant entity based on the interactions between the target entity and that participant entity, the interactivity model for a participant entity including totals of interactions between the target entity and that participant entity covering multiple time frames;

receiving a query that specifies an interactivity criterion, the interactivity criterion specifying a characteristic of an interactivity model;

analyzing interactivity models to determine whether the interactivity criterion is satisfied wherein a participant entity satisfies the interactivity criterion when the interactivity model for the participant exhibits the characteristic; and

when the interactivity criterion is satisfied, sending a response to the query indicating that the interactivity criterion is satisfied.

16. The method of claim 15 wherein the total for the most recent time frame is updated in real time as indications of interactions are received.

17. The method of claim 15 wherein the target entity satisfies the interactivity criterion when the interactivity models exhibit the characteristic.

18. The method of claim 15 wherein the response identifies the participant entities that satisfy the interactivity criterion.

19. The method of claim 15 wherein interactivity models are generated for multiple target entities and stored in a distributed manner.

20. The method of claim 15 wherein each interaction has an interaction type that is selected from a group consisting of an electronic mail message, a text message, an instant message, a scheduled meeting, a voice mail, a phone call, and a document collaboration.
