Enhanced relationship graph signals are provided. A productivity service initiates operations to provide enhanced relationship graph signals by retrieving relationship attribute(s) between two users of a productivity service. Interactivity attribute(s) between the two users of the product service are also retrieved. An enhanced signal is generated based on the relationship and interactivity attributes. The enhanced signal is stored within a relationship graph.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method executed on a computing device to provide enhanced relationship graph signals, the method comprising: retrieving one or more relationship attributes between two users of a productivity service; retrieving one or more interactivity attributes between the two users of the productivity service; generating an enhanced signal based on the relationship and interactivity attributes; and storing the enhanced signal within a relationship graph. 2. The method of claim 1, wherein retrieving the one or more relationship attributes and the one or more interactivity attributes comprises analyzing in each communication one or more of: an address of a recipient, an address of a sender, an address of a co-recipient, a date and time of a transmission, a subject, and a topic extracted from a content of the communication. 3. The method of claim 1, wherein retrieving the one or more relationship attributes further comprises: receiving one or more of an organizational relationship signal and a social distance signal from the relationship graph; and analyzing the organizational relationship signal and the social distance signal to retrieve the one or more relationship attributes. 4. The method of claim 3, wherein the organizational relationship signal describes a relationship between the two users that includes an associate relationship, a supervisory relationship, and a subordinate relationship. 5. The method of claim 3, wherein retrieving the one or more relationship attributes further comprises: receiving one or more of an organizational distance signal and a managerial relationship signal from the relationship graph, wherein the organizational distance signal describes a number of people between the two users within an organization; and analyzing the organizational distance signal and the managerial relationship signal to retrieve the one or more relationship attributes. 6. The method of claim 1, wherein retrieving the one or more relationship attributes and the one or more interactivity attributes further comprises: querying the relationship graph for one or more signal values associated with one or more stored signals, wherein the one or more signal values are normalized to values within a value range. 7. The method of claim 6, wherein a low value within the value range for a distance signal correlates to fewer people between the two users and a high value within the value range for the distance signal correlates to more people between the two users. 8. The method of claim 6, wherein a low value within the value range for an interactivity signal correlates to fewer interactions between the two users and a high value within the value range for the interactivity signal correlates to more frequent interactions between the two users. 9. The method of claim 6, further comprising: applying a weight value to each signal value. 10. The method of claim 9, wherein the weight value is adjustable by one or more of: one of the two users, a stakeholder, and a machine learning scheme that is configured to process the signals. 11. The method of claim 1, wherein retrieving the one or more interactivity attributes further comprises: querying the relationship graph for a modification signal, wherein the modification signal describes a collaboration between the two users; querying the relationship graph for a present relationship signal, wherein the present relationship signal describes an ongoing relationship between the two users; querying the relationship graph for an interaction frequency signal, wherein the interaction frequency signal describes a frequency of the one of more interactions between the two users; and analyzing the one or more of the modification signal, the present relationship signal, and the interaction frequency signal to retrieve the one or more interactivity attributes. 12. A productivity server to provide enhanced relationship graph signals, the productivity server comprising: a communication device; a memory configured to store instructions associated with a productivity service; one or more processors coupled to the memory and the communication device, the one or more processors executing the productivity service in conjunction with the instructions stored in the memory, wherein the productivity service includes: an inference engine configured to: retrieve one or more relationship attributes between two users of the productivity service; retrieve one or more interactivity attributes between the two users of the productivity service; generate an enhanced signal based on the relationship and interactivity attributes; and store the enhanced signal within a relationship graph. 13. The productivity server of claim 12, wherein the inference engine is further configured to: receive a communication directed to a user of the productivity service; query the relationship graph for the enhanced signal associated with the user and/or the communication; and provide a value of the enhanced signal to a communication module to rank the communication among a plurality of communications. 14. The productivity server of claim 13, wherein the inference engine is configured to retrieve the one or more relationship attributes and the one or more interactivity attributes by: querying the relationship graph for a plurality of signals associated with the user and/or the communication: and analyzing the plurality of signals to retrieve the one or more relationship attributes and the one or more interactivity attributes. 15. The productivity server of claim 14, wherein the plurality of signals include signals that indicate one or more of people who communicate with the user often, people the user is close to, a context of the communication trending around the user's colleagues, an importance of the communication, a relevance of the user based on an organizational distance to a sender of the communication, people who are in the communication and are relevant to the user, an explicit reference to the user in a body of the communication, the email is directed only to the user, how influential the sender of the communication is, a relevance of a topic of the communication to the user, and a proximity or a relationship between the user and the sender through a management chain. 16. The productivity server of claim 15, wherein the explicit reference to the user in the body of the communication include one or more of a tag reference to the user and a name of the user being included in the body of the communication. 17. The productivity server of claim 13, wherein the inference engine is further configured to: update the enhanced signal based on the communication; and store the updated enhanced signal. 18. A system to provide enhanced relationship graph signals, the system comprising: one or more cloud servers executing a cloud service, the cloud service configured to: maintain the relationship graph; a productivity server executing a productivity service, the productivity service configured to: detect the communication sent to a user; query the relationship graph for a plurality of signals; retrieve one or more relationship attributes and one or more interactivity attributes between the user and a sender of the communication based on analyzing the plurality of signals; generate an enhanced signal based on the relationship and interactivity attributes; and rank the communication based on the enhanced signal. 19. The system of claim 18, wherein the productivity service is further configured to: query the relationship graph for at least one other enhanced signal; and further rank the communication based on the at least one other enhanced signal. 20. The system of claim 18, wherein the productivity service is further configured to: provide the enhanced signal to the cloud service to be stored in the relationship graph.
