Abstract

Methods and apparatus are provided for collecting proxy presence information about an object associated with a user from one or more proxy presence sources associated with the user. A proxy presence agent is associated with each of the proxy presence sources; and the proxy presence agents provide proxy presence information to one or more presence servers. The object may be, for example, one or more of a business document, an application document, or one or more runtime objects associated with the user. The proxy presence agent reports one or more of macropresence events and micropresence events related to the object. A continuous presence function is generated for each of the proxy presence sources that characterizes the likelihood that the object is active at the corresponding presence source at a given time. The proxy presence sources may include, for example, one or more business applications, application execution environments, devices or locations.

Claims

1. A method comprising:

receiving, at a first time and from a first presence agent associated with a first presence source, a first indication of a presence of a user at the first presence source;

receiving, at a second time and from a second presence agent associated with a second presence source, a second indication of presence of the user at the second presence source;

determining a first likelihood that the user is available at the first presence source at a third time later than the first time and the second time by applying a first monotonically decreasing and continuous function to a first difference between the first time and the third time;

determining a second likelihood that the user is available at the second presence source at the third time by applying a second monotonically decreasing and continuous function to a second difference between the second time and the third time; and

determining an overall presence of the user at the third time by computing a weighted average of the first likelihood and the second likelihood.

2. The method of claim 1, wherein the presence source comprises one of a business document, an application document, or a runtime object associated with the user.

3. The method of claim 1, further comprising:

determining at which one of the first presence source or the second presence source the user is more likely to be available at the third time by comparing the first likelihood and the second likelihood.

4. The method of claim 1, further comprising

determining an updated likelihood that the user is available at the first presence source at a fourth time later than the third time by applying the first monotonically decreasing and continuous function to a third difference between the first time and the fourth time, when a fourth difference between the third time and the fourth time exceeds a threshold.

5. The method of claim 1, further comprising recording the first indication and a time associated with the first indication.

6. The method of claim 1, wherein the first indication comprises a likelihood that an object is active at the first presence source.

7. The method of claim 1, wherein the first presence source comprises one of a business application, an application execution environment, a device, or a location.

8. The method of claim 1, wherein the first indication is provided by a database trigger operating on a database associated with the first presence source.

9. The method of claim 1, wherein the first indication is provided by a node of a workflow executed by the first presence source.

10. A system comprising:

a processor; and

a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising;

receiving, at a first time and from a first presence agent associated with a first presence source, a first indication of a presence of a user at the first presence source;

receiving, at a second time and from a second presence agent associated with a second presence source, a second indication of presence of the user at the second presence source;

determining a first likelihood that the user is available at the first presence source at a third time later than the first time and the second time by applying a first monotonically decreasing and continuous function to a first difference between the first time and the third time;

determining a second likelihood that the user is available at the second presence source at the third time by applying a second monotonically decreasing and continuous function to a second difference between the second time and the third time; and

determining an overall presence of the user at the third time by computing a weighted average of the first likelihood and the second likelihood.

11. The system of claim 10, wherein the first presence source comprises one of a business document, an application document, or a runtime object associated with the user.

12. The system of claim 10, wherein the computer-readable storage medium stores additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:

determining at which one of the first presence source or the second presence source the user is more likely to be available at the third time by comparing the first likelihood and the second likelihood.

13. The system of claim 10, wherein the computer-readable storage medium stores additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:

determining an updated likelihood that the user is available at the first presence source at a fourth time later than the third time by applying the first monotonically decreasing and continuous function to a third difference between the first time and the fourth time, when a fourth difference between the third time and the fourth time exceeds a threshold.

14. The system of claim 10, wherein the computer-readable storage medium stores additional instructions which, when executed by the processor, cause the processor to perform further operations comprising recording the indication and a time associated with the first indication.

15. The system of claim 10, wherein the first indication comprises a likelihood that the object is active at the first presence source.

16. The system of claim 10, wherein the first presence source comprises one of a business application, an application execution environment, a device, or a location.

17. The system of claim 10, wherein the first indication is provided by a database trigger operating on a database associated with the first presence source.

18. The system of claim 10, wherein the first indication is provided by a node of a workflow executed by the first presence source.

19. A non-transitory computer readable medium storing instructions which, when executed by a processor, cause the processor to perform operations comprising:

receiving, at a first time and from a first presence agent associated with a first presence source, a first indication of a presence of a user at the first presence source;

receiving, at a second time and from a second presence agent associated with a second presence source, a second indication of presence of the user at the second presence source;

determining a first likelihood that the user is available at the first presence source at a third time later than the first time and the second time by applying a first monotonically decreasing and continuous function to a first difference between the first time and the third time;

determining a second likelihood that the user is available at the second presence source at the third time by applying a second monotonically decreasing and continuous function to a second difference between the second time and the third time; and

determining an overall presence of the user at the third time by computing a weighted average of the first likelihood and the second likelihood.
