Abstract

An automated task centered collaboration technique is described that significantly lowers the technological entry barrier for the development and deployment of a broad class of collaborative applications, which are termed Task Centered Collaboration (TCC) applications. TCC applications facilitate the processing of a large number of work items, or tasks, by people working independently or in small, synchronously collaborating groups. The technique also provides a mechanism for the study of computer mediated communication and human-computer interactions for this class of applications. The technique creates an abstraction applicable to the broad class of TCC applications, which enables the factoring out of significant portions of the application into a common infrastructure. It provides a programming model that enables a developer to focus on the User Interface and logic associated with operations on a single task, without being exposed to issues such as security, authentication, binding users to activities, synchronization, concurrency and persisting data.

Claims

1. A computer-implemented creating an application for assigning tasks of a project that can be distributed to a number of actors over a network for the actors to collaboratively complete the tasks, comprising:

for tasks of a project, defining data structures to represent task data and solution data;

creating project activities that enable interaction between actors and tasks; and

uploading the tasks and activities to a server for distribution to one or more actors to collaboratively determine solutions for the tasks.

2. The process of claim 1 wherein creating project activities and uploading tasks to a server, for each activity further comprises:

partitioning each activity into a logic engine and a user interaction component;

defining data structure and messages for communication for each activity;

programming a logic engine and user interface for each activity;

3. The computer-implemented process of claim 1 further comprising obtaining solutions to the tasks wherein each task is performed by the one or more actors in stages and wherein a solution to a task created in each stage is added to the task.

4. The computer-implemented process of claim 1 further comprising receiving information on actor behavior concerning actors'"'"' time-stamped interactions while performing activities.

5. The computer-implemented process of claim 1 wherein the task data further comprises a unit of work comprising a task input, task constraints and a list of solutions.

6. The computer-implemented process of claim 2 wherein the logic engine is a finite state device that advances each time a message is received or at periodic intervals.

7. The computer-implemented process of claim 2 wherein the logic engine executes within the context of a room that comprises at least one activity, a task list and an actor list.

8. The computer-implemented process of claim 5 wherein the tasks constraints are metadata used to match actors, tasks and activities.

9. The computer-implemented process of claim 1 wherein solution data is data appended to a task by the one or more actors participating in an activity.

10. A computer-implemented process for creating and using a collaborative application, comprising:

accessing an abstraction of pre-programmed program modules for common features of a collaborative application where tasks are assigned to one or more actor clients over a network for completion;

using the abstraction, creating a collaborative application using the pre-programmed program modules for the common features;

assigning tasks of the collaborative application to the one or more actors over a network to complete tasks defined by the collaborative application program; and

receiving completed tasks of the collaborative application program from the one or more actor clients.

11. The computer-implemented process of claim 10, further comprising:

receiving data from the collaborative application program on the behavior of the one or more actor clients while completing the tasks of the collaborative application program.

12. The computer-implemented process of claim 10 wherein the pre-programmed program modules for the common features of a collaborative application, further comprise modules for performing at least one of the group of:

user authentication and management;

data base management and access;

synchronization for multi-user collaborative tasks;

management of task life cycles;

security and protection from malicious entities; and

administration for managing tasks.

13. The computer-implemented process of claim 11 wherein the pre-programmed program modules for the common features of a collaborative application, further comprise modules for performing:

analysis of usage data; and

monitoring and evaluation of actor behavior.

14. The computer-implemented process of claim 10 wherein creating a collaborative application using the pre-programmed program modules for common features, further comprises:

inputting each task that needs to be completed by the one or more actors over a network;

for each task, creating activities that allow interaction between a task and an actor and that define program logic and a user interface for completion of the task;

assigning a unique token to classify the tasks and activities into a project;

receiving from the one or more client actors messages regarding the tasks and queuing the messages in a queue;

using the program logic to determine what actions to take on messages in the queue;

when each task is complete, storing a task solution for each task in a database; and

accessing the task solution for each task in the database in order to determine the task solution for the task.

15. A system for creating a collaborative application for distributed computing, comprising:

a general purpose computing device;

a computer program comprising program modules executable by the general purpose computing device, wherein the computing device is directed by the program modules of the computer program to,

author a collaborative project where project tasks are created by an author by accessing a project authoring application containing pre-programmed program modules for the common features of a collaborative application where tasks are assigned to multiple actors;

assign tasks of the collaborative project to the multiple actors to complete tasks using a task services module;

manage the completion of tasks using the task services module and a logic server;

store solutions to completed tasks in a database; and

receive completed tasks from the multiple actors by accessing solutions to the tasks stored in a database.

16. The system of claim 15 wherein the logic server, further comprises:

logic engines;

a logic engine executor that executes the logic engines provided by the authors;

a queue-manager that manages the execution of messages received from the multiple actors;

a state-manager that maintains states for tasks, activities, actors;

a scheduler that schedules the execution of tasks;

a coordinator that coordinates the logic engine executor, the queue manager, the state-manager and the scheduler.

17. The system of claim 15 wherein an actor can be a computational resource performing a computationally intensive task or accessing external data.

18. The system of claim 15 wherein actors can download one or more tasks to work on when offline, and subsequently connect and upload completed tasks.

19. The system of claim 15 wherein static analysis is performed on activity-related code provided by authors to validate proper functioning of the code and disallow malicious or inappropriate functionality in the code.

20. The system of claim 15 where multiple activities are orchestrated on a task by specification of suitable task constraints for each activity.
