Abstract

An activity scheme designer may associate an activity scheme with a task of a process model that includes a plurality of tasks, the activity scheme including a directed graph of nodes in which the nodes represent knowledge actions to be performed at least partially by human users, and in which edges of the directed graph connecting the nodes are probabilistically weighted. A workflow engine may instantiate the process model for execution, including associating an instance of the task with a user of the human users, the task instance including instance-specific data associated with completing the execution. An activity scheme transformer may transform the activity scheme for the user, based on the instance-specific data, a context of the user including applications and information resources available to the user, and a personal profile of the user.

Claims

1. A system including instructions recorded on a non-transitory computer-readable storage media and executable by at least one processor, the system comprising:

an activity scheme designer configured to cause the at least one processor to associate an activity scheme with a task of a process model that includes a plurality of tasks, the activity scheme including a directed graph of nodes in which the nodes represent knowledge actions to be performed at least partially by human users, and in which edges of the directed graph connecting the nodes are probabilistically weighted;

a workflow engine configured to cause the at least one processor to instantiate the process model for execution, including associating an instance of the task with a user of the human users, the task instance including instance-specific data associated with completing the execution; and

an activity scheme transformer configured to cause the at least one processor to transform the activity scheme for the user, based on the instance-specific data, a context of the user including applications and information resources available to the user, and a personal profile of the user.

2. The system of claim 1, comprising:

an activity monitor configured to cause the at least one processor to monitor activities of the user associated with the context.

3. The system of claim 2, comprising:

a personalized activity scheme repository configured to store a plurality of transformed activity schemes associated with the user, including the transformed activity scheme; and

an activity scheme assigner configured to cause the at least one processor to receive monitor data from the activity monitor and to identify the transformed activity scheme from the plurality of activity schemes as being currently executed by the user, based on the monitor data.

4. The system of claim 3, wherein the activity scheme assigner is further configured to cause the at least one processor to identify a current knowledge action node being executed by the user within the context, based on the identified, transformed activity scheme and on the monitor data.

5. The system of claim 2, comprising:

a scheme-based recommender configured to recommend a subsequent knowledge action node for execution by the user, based on monitor data received from the activity monitor and on the probabilistically-weighted edges output from a current knowledge action node.

6. The system of claim 2, comprising:

a scheme-based recommender configured to cause the at least one processor to recommend a current activity for implementing a current knowledge action node of the transformed activity scheme, using a current application and information resource associated with the current activity and the current knowledge action.

7. The system of claim 2, comprising:

an activity scheme enhancer configured to cause the at least one processor to detect a non-included activity that is not included in knowledge action nodes of the transformed activity scheme, and to determine inclusion of the non-included activity within the transformed activity scheme to obtain an enhanced transformed activity scheme.

8. The system of claim 7, wherein the activity scheme enhancer is further configured to cause the at least one processor to disassociate the instance-specific data and the context from the enhanced transformed activity scheme to obtain a generalized activity scheme for updating the activity scheme therewith.

9. The system of claim 2, wherein an activity scheme enhancer associated with the activity scheme designer is configured to cause the at least one processor to update probabilities of the probabilistically-weighted edges of the activity scheme, based on monitor data received from the activity monitor.

10. The system of claim 1 wherein the activity scheme transformer is configured to cause the at least one processor to transform the activity scheme including replacing placeholder applications and information resources with specific applications and information resources associated with the context.

11. The system of claim 1 wherein each knowledge action includes a data triplet identifying an activity to be performed by an application, using an information resource.

12. The system of claim 1, comprising:

an application server configured to cause the at least one processor to associate the activity scheme with the at least one task of the process model including retrieving the process model from a process model repository and retrieving the activity scheme from an activity scheme repository, and including linking the retrieved at least one task with the retrieved activity scheme.

13. The system of claim 1, wherein the personal profile includes competency information related to the user with respect to the at least one task and/or the activity scheme.

14. A method including executing instructions recorded on a non-transitory computer-readable storage media using at least one processor, the method comprising:

associating, using at least one processor, an activity scheme with a task of a process model that includes a plurality of tasks, the activity scheme including a directed graph of nodes in which the nodes represent knowledge actions to be performed at least partially by human users, and in which edges of the directed graph connecting the nodes are probabilistically weighted;

instantiating, using at least one processor, the process model for execution, the instantiating including associating an instance of the task with a user of the human users, the task instance including instance-specific data associated with completing the execution; and

transforming, using at least one processor, the activity scheme for the user, based on the instance-specific data, a context of the user including applications and information resources available to the user, and a personal profile of the user.

15. The method of claim 14, comprising monitoring, using the at least one processor, activities of the user associated with the context, to thereby obtain monitor data, and further comprising identifying the transformed activity scheme from a plurality of activity schemes as being currently executed by the user, based on the monitor data.

16. The method of claim 14, comprising monitoring, using the at least one processor, activities of the user associated with the context, to thereby obtain monitor data, and further comprising recommending a subsequent knowledge action node for execution by the user, based on the monitor data and on the probabilistically-weighted edges output from a current knowledge action node.

17. A computer program product including instructions recorded on a non-transitory computer readable storage media, which, when executed by at least one processor, cause the at least one processor to:

associate an activity scheme with a task of a process model that includes a plurality of tasks, the activity scheme including a directed graph of nodes in which the nodes represent knowledge actions to be performed at least partially by human users, and in which edges of the directed graph connecting the nodes are probabilistically weighted;
