TASK ASSIGNMENT IN CROWDSOURCING
Systems and methods for task assignment in crowdsourcing are described. In one implementation, a method comprises receiving task information from a requester, the task information comprising at least details of a task, an accuracy level for task completion, and a budget for the task. The method further comprises computing expected costs of completing the task to achieve the accuracy level within the budget based on the task information, and recommending an assignment of the task to agents based on the computation.
1 . A crowdsourcing system ( 102 ) comprising:
a processor ( 110 ):
a task receipt module ( 120 ) coupled to the processor ( 110 ), the task receipt module ( 120 ) configured to receive task information from a requester, the task information comprising at least details of a task, an accuracy level for task completion, and a budget for the task; and
a task assignment module ( 122 ) coupled to the processor ( 110 ), the task assignment module ( 122 ) configured to recommend an assignment of the task to agents based on a comparison of expected costs of completing the task to achieve the accuracy level within the budget.
2 . The crowdsourcing system ( 102 ) as claimed in claim 1 , wherein the task assignment module ( 122 ) is configured to recommend one of a random assignment, an oracle assignment and a referral based assignment as the assignment.
3 . The crowdsourcing system ( 102 ) as claimed in claim 2 , wherein the task assignment module ( 122 ) is configured to recommend one of a referral assignment, a random-referral hybrid assignment and an oracle-referral hybrid assignment as the referral based assignment.
4 . The crowdsourcing system ( 102 ) as claimed in claim 1 , wherein the task assignment module ( 122 ) is configured to determine an upper bound on a referral payment for the task when a referral based assignment is recommended for completing the task.
5 . The crowdsourcing system ( 102 ) as claimed in claim 1 , wherein the task assignment module ( 122 ) is configured to compute the expected costs based on the task information and an agent capability distribution.
6 . The crowdsourcing system ( 102 ) as claimed in claim 1 , wherein
the task receipt module ( 120 ) is configured to receive an agent criteria comprising minimum qualifications for an agent to attempt the task; and
the task assignment module ( 122 ) is configured to pre-screen the agents based on the agent criteria.
7 . The crowdsourcing system ( 102 ) as claimed in claim 1 further comprising a solution aggregation module ( 124 ) coupled to the processor ( 110 ), the solution aggregation module ( 124 ) configured to receive solutions from the agents and determine an aggregate solution for the task.
8 . A method for task assignment in crowdsourcing, the method comprising:
receiving task information from a requester, the task information comprising at least details of a task, an accuracy level for task completion, and a budget for the task;
computing expected costs of completing the task to achieve the accuracy level within the budget based on the task information; and
recommending an assignment of the task to agents based on the computation.
9 . The method as claimed in claim 8 , wherein the recommending the assignment comprises recommending one of an oracle assignment, a random assignment, a referral assignment, and a hybrid assignment.
10 . The method as claimed in claim 9 , wherein the hybrid assignment comprises:
selecting a seed set based on one of the oracle assignment and the random assignment; and
assigning the task to the seed set at least for referral.
11 . The method as claimed in claim 8 further comprising determining an upper bound on a referral payment for the task when a referral based assignment is recommended for completing the task.
12 . The method as claimed in claim 8 , wherein the computing the expected costs comprises selecting an agent capability distribution based at least in part on past performance of the agents.
13 . The method as claimed in claim 8 further comprising receiving an agent criteria comprising minimum qualifications for an agent to attempt the task; and pre-screening an agent pool based on the agent criteria.
14 . The method as claimed in claim 8 further comprising receiving solutions from the agents and determining an aggregate solution for the task.
15 . A non-transitory computer readable medium ( 304 ) comprising instructions executable by a processor to;
receive task information from a requester, the task information comprising at least details of a task, an accuracy level for task completion, and a budget for the task;
compute expected costs of completing the task to achieve the accuracy level within the budget based on the task information and an agent capability distribution; and
recommend an assignment of the task to agents based on the computation.
16 . The non-transitory computer readable medium ( 304 ) as claimed in claim 15 , wherein the assignment is one of a random assignment, an oracle assignment, a referral assignment, a random-referral hybrid assignment and an oracle-referral hybrid assignment.
17 . The non-transitory computer readable medium ( 304 ) as claimed in claim 15 , wherein the set of computer readable instructions, when executed, perform further acts to determine an upper bound on a referral payment for the task when a referral based assignment is recommended for completing the task.
