The present disclosure relates to multi-task systems in general, and to allocating tasks to agents in a multi-task system, in particular.
Multi-task systems are system in which there is a plurality of separate tasks to be performed. Each task may be performed by a different agent and may be allocated accordingly. In some cases, the agents are not necessarily committed to the system and there may be no guarantee that they will perform tasks in a reasonable quality. The tasks may be tasks of performing a service, performing a computation, providing computational resources, producing content, providing ideas, or the like.
Crowd-sourcing is a methodology in which “free” agents perform tasks in a multi-task system. In crowd-sourcing, contributions are solicited from a large group of people, such as from online communities, rather than from traditional non-free agents, such as employees or suppliers. In some cases, crowd-sourcing represents the act of a company or institution taking a function once performed by employees and outsourcing it to an undefined (and generally large) network of people in the form of an open call. This can take the form of peer-production (e.g., when the job is performed collaboratively), but may also be undertaken by sole individuals. The process may combine efforts of numerous self-identified volunteering agents or part-time workers, where each contributor of their own initiative adds a small portion to the greater result.
Crowd-sourcing may be used for human-powered solving of large scale problems in numerous domains such as image classification, data entry, optical character recognition, recommendation, and proofreading. In recent years, more and more tasks are done via some sort of crowd sourcing. Examples include routing, such as using reports from a community (e.g., WAZE™), sourcing the community for funding (e.g. KICKSTARTER™), solving hard problems such as protein folding (e.g., FOLD IT™), developing software (e.g., SOURCEFORGE™) and more. In some cases, tasks are assigned to agents that perform them without long term relationship or commitment such as exists e.g. in a traditional work place or when using traditional contractors.
One exemplary embodiment of the disclosed subject matter is A method comprising: obtaining a stream of tasks in a system, wherein the tasks are to be performed by agents, wherein the agents choose whether or not to perform a task, wherein a quality of each agent affects contributions of performing tasks by the agent; calculating, by a processor, for each agent, an average quality of tasks in the system that were completed in the past by the agent; allocating, by the processor, the tasks to the agents, wherein allocating comprises selecting an agent to perform a task, wherein selecting is based on the average quality of the agent; obtaining an indication that the agent has completed the task; in response to the indication, computing, by the processor, a reward for the agent, wherein the reward is calculated according to a total contribution of the agent to the system by completing the task; outputting the reward to be provided to the user; whereby biasing the allocation to prefer allocating tasks to a first agent over a second agent, if a quality of the first agent is greater than a quality of the second agent, wherein the biasing is not dependent on prior knowledge of the qualities.
Another exemplary embodiment of the disclosed subject matter is a computerized apparatus having a processor, the processor being adapted to perform the steps of: obtaining a stream of tasks in a system, wherein the tasks are to be performed by agents, wherein the agents choose whether or not to perform a task, wherein a quality of each agent affects contributions of performing tasks by the agent; calculating for each agent, an average quality of tasks in the system that were completed in the past by the agent; allocating the tasks to the agents, wherein allocating comprises selecting an agent to perform a task, wherein selecting is based on the average quality of the agent; obtaining an indication that the agent has completed the task; in response to the indication, computing a reward for the agent, wherein the reward is calculated according to a total contribution of the agent to the system by completing the task; outputting the reward to be provided to the user; whereby biasing the allocation to prefer allocating tasks to a first agent over a second agent, if a quality of the first agent is greater than a quality of the second agent, wherein the biasing is not dependent on prior knowledge of the qualities.
Yet another exemplary embodiment of the disclosed subject matter is a computer program product comprising a computer readable storage medium retaining program instructions, which program instructions when read by a processor, cause the processor to perform a method comprising: obtaining a stream of tasks in a system, wherein the tasks are to be performed by agents, wherein the agents choose whether or not to perform a task, wherein a quality of each agent affects contributions of performing tasks by the agent; calculating for each agent, an average quality of tasks in the system that were completed in the past by the agent; allocating the tasks to the agents, wherein allocating comprises selecting an agent to perform a task, wherein selecting is based on the average quality of the agent; obtaining an indication that the agent has completed the task; in response to the indication, computing a reward for the agent, wherein the reward is calculated according to a total contribution of the agent to the system by completing the task; outputting the reward to be provided to the user; whereby biasing the allocation to prefer allocating tasks to a first agent over a second agent, if a quality of the first agent is greater than a quality of the second agent, wherein the biasing is not dependent on prior knowledge of the qualities.
The present disclosed subject matter will be understood and appreciated more fully from the following detailed description taken in conjunction with the drawings in which corresponding or like numerals or characters indicate corresponding or like components. Unless indicated otherwise, the drawings provide exemplary embodiments or aspects of the disclosure and do not limit the scope of the disclosure. In the drawings:
One technical problem dealt with by the disclosed subject matter is to allocate tasks to agents in a multi-task system. The tasks may be assigned by a multi-task system to agents, which may not be committed to the system. In some cases, and in particular when the agents are humans and not computational devices, different agents may perform different tasks at different quality levels. As an example, the tasks may be to annotate images, which some agents may perform better than others. Other non-limiting examples of tasks may be rating search engine results, collection of labeled data, text translation, or the like. In such scenarios, in particular when high quality is an issue for the multi-task system, the system may compensate the agents, in money or otherwise, in order to obtain high quality performance. Moreover, the system is likely to be unaware of the agents' capabilities in advance (e.g., quality of the agent).
In some exemplary embodiments, the agents may choose whether or not to perform a task. The agents may and are potentially likely to maximize their own utility. A quality of an agent may affect contributions of performing tasks by the agent. In some exemplary embodiments, some agents may be more qualified than other agents. Additionally or alternatively, some agents may be more dedicated to the system than others. The disclosed subject matter may aspire to allocate the tasks to the most qualified agents. Such an allocation would cause the aggregated quality of the completed tasks to get close to the maximal potential aggregated quality. The most qualified agents may be agents having the highest qualities and hence they produce high quality results in performing the tasks. In some cases, the quality of an agent is high as the agent requires relatively a small amount of effort to complete the tasks (e.g., completes the task fast). In other cases, the quality of agent reflects the agent's capabilities, such as how smart the agent is, how diligently he performs his tasks, or the like.
In some cases, the quality of a task completed by an agent may be a statistical random variable whose median, average or mean value is the quality of the agent. As an example, an agent of high quality may produce low quality results in some cases. Hence, a quality of a recent completed task may not necessarily be indicative of the quality of the agent. As another example, in some cases, an agent may not be able to complete a task, and the task may be re-allocated to another agent. In such a case, the quality of the allegedly completed task by the agent may be a minimal quality such as indicated by zero or even a negative contribution to the system.
One technical solution is to select an agent to perform a task based on an average quality of the agent. In some exemplary embodiments, the average quality of the agent may be calculated based on the average quality of tasks in the system that were completed in the past by the agent. In some exemplary embodiments, the selection may be probabilistic so as to allow agents who have high quality who initially produced poor results to prove themselves.
In some exemplary embodiments, in case of a new agent, for which there is no available history, an estimation may be performed as to the quality of the agent. The estimated quality may be a default quality, an average quality of the other agents, or the like. In some exemplary embodiments, a machine learning module may be used to predict the quality of the agent based on attributes such as age, gender, nationality, location, demographic information, credentials, or the like. In some exemplary embodiments, the training set may be the agents for which the average quality is computed.
In some exemplary embodiments, if the quality of the agents was a-priori known, selecting the best agents could have been performed without a probabilistic selection, but rather based on the known qualities. As the qualities are revealed by the completed tasks, and as their quality may be poor even for agents with high qualities, the probabilistic selection may be useful to compensate for the lack of knowledge and provide all agents a chance of proving themselves even if they originally did not provide good results.
In some exemplary embodiments, the average quality of tasks in the system that were completed in the past by the agent may be calculated by dividing a summation of contributions to the system of tasks completed in the past by the agent, by a number of tasks in the system that were performed in the past by the agent.
In some exemplary embodiments, a reward may be calculated for each agent based on the completed tasks. The reward may be provided to the agent to incentivize the user to perform the current tasks in high quality as well and thereby to continue contributing to the system. In some exemplary embodiments, the reward may be provided in a monetary form, funny money, credits, recognition, or the like. In some exemplary embodiments, a reward for the agent may be computed after the agent has completed one or more tasks. The reward may be calculated according to total contribution of the agent to the system by completing the one or more tasks.
In some exemplary embodiment, allocating the tasks may be based on a probabilistic selection of an agent to perform the task. The probabilistic selection may be based on a set of probabilities, each of which is associated with an agent. The probability to select an agent may be based on an average quality of the agent. In some exemplary embodiment, allocating the tasks may comprise applying a probabilistic regret minimization algorithm to select agents to perform the tasks. A probability to select agent i by the probability regret minimization algorithm may be based on the following formula:
In some exemplary embodiments, pi may be the probability to select agent i. γ may be a value between zero and one. In some cases, γ may be a parameter value that is provided to the formula based on configurations, user preferences, or the like. qi may be the average quality associated with agent i. n may be a number of agents from which the selection is made.
One technical effect of utilizing the disclosed subject matter is to automatically assign tasks to the most qualified agents even in the absence of objective information regarding the qualification of each agent. Accordingly, the total gain of the system may be improved when compared to the gain of the system under a random assignment of tasks to agents. In some cases, more qualified agents are assigned more tasks than less qualified agents. The more qualified agents may be rewarded more than the less qualified agents, both when viewing per task reward and a total reward. The system is therefore configured to allocate its resources in a manner which invests more in incentivizing the agents which are most qualified to assist the system in accomplishing its goals. The incentives that are provided to the agents are also configured to incentivize the more qualified agents to take on more tasks, invest more effort and contribute more to the system than less qualified agents.
In some exemplary embodiments, the automatic allocation of the disclosed subject matter together with the computed rewards are implemented in a computerized environment, which is capable of monitoring a large number of agents and completed tasks and is capable of efficiently allocating, in a relatively rapid manner, the tasks to the agents so as not to cause any delay in allocating tasks. In fact, in some cases, the agents may be unaware of the allocation mechanism and less qualified agents who are not assigned a task may simply assume that there are no task available and not that the tasks are constantly being allocated to other, more qualified, agents.
In some exemplary embodiments, the disclosed subject matter may be useful in loosely-coupled organizations such as those employing crowd sourcing methodologies to incentivize high quality agents to contribute more and low quality agents to contribute less.

In Step 110, a stream of tasks in a system, such as a multi-task system, may be obtained. The tasks may tasks that are to be performed by agents. The agents may choose whether or not to perform a task.
In some exemplary embodiments, the tasks may be discrete tasks broken out of a higher-level task. The discrete tasks may be handled by several distributed agents. The tasks may or may not be related to each other, such as some tasks may be performed in sequence, some tasks may be performed in parallel, or the like.
In some exemplary embodiments, the tasks may be technical tasks, such as: translation tasks, transcription tasks, photo tagging, keyword optimization tasks, data verification tasks, testing tasks (e.g., website testing tasks, beta software testing tasks, etc.), article writing tasks, or the like. Additionally or alternatively, the tasks may be creative Tasks. For example: design tasks, video producing tasks, or the like.
In Step 120, information about agents may be obtained. The information about agents may include information about performance of an agent in tasks performed in the past by the agent, information about a contribution of an agent to the system, or the like. The information does not include a-priori known quality of each agent. In some exemplary embodiments, a quality of an agent may affect contribution of performing tasks by the agent.
In Step 130, an average quality may be calculated for each agent based on the agent's past performance in the system. The average quality may be an average quality of tasks in the system that were completed in the past by the agent. In some exemplary embodiments, the average quality of an agent may be calculated as an average of qualities of tasks in the system, completed in the past by the agent. A quality of a task performed by an agent may be measured by a contribution of the completed task to the system. In some exemplary embodiments, the average quality of tasks in the system that were completed in the past by the agent may be calculated by dividing a summation of contributions to the system of tasks completed in the past by the agent, by a number of tasks in the system that were performed in the past by the agent. However, it will be noted that the average quality of tasks may be computed in a different manner.
In some exemplary embodiments, the average quality of tasks in the system, performed by an agent may be calculated based on the following formula: qi=1/ni. Σj(i)vj. In some exemplary embodiments, ni may be a number of tasks in the system that were performed in the past by agent. vj may be an quality of task j, which was performed by agent i.
In Step 140, the tasks may be allocated to the agents. In some exemplary embodiments, an agent may be selected to perform a task based on the average quality of the agent.
In some exemplary embodiments, allocating the tasks may be based on a probabilistic selection of an agent to perform a task. The probabilistic selection may be based on a set of probabilities. Each agent have a probability to be selected. Each probability may be based on an average quality of the agent.
In some exemplary embodiments, allocating the tasks may be based on applying a probabilistic regret minimization algorithm to select agents to perform the tasks. The probabilistic regret minimization algorithm may be implement an online learning and estimation of the agents' qualities. In some exemplary embodiments, regret may be defined as the difference between an actual payoff and a payoff that would have been obtained if a different course of action had been chosen. The probabilistic regret minimization algorithm may be based on minimizing the worst-case regret. The aim of the minimization may be to perform as closely as possible to the optimal course. In some exemplary embodiments, the regret may be selecting a wrong agent to complete the task or not selecting the best agent to complete the task.
In some exemplary embodiment, a probability to select agent i by the probability regret minimization algorithm may be based on the following formula:
In some exemplary embodiments, γ may be a value between zero and one. qi may be the average quality associated with agent i. In some exemplary embodiments, n may be a number of agents from which the probability minimization algorithm is configured to select. The probability to select an agent may combine a uniform distribution
and a distribution which assign to each agent a probability mass that is exponential in the estimated cumulative quality of the agent
Using an exponential function may allow for a slight advantage of one agent of another to provide a meaningful biasing of the allocation in favor of the better agent.
In some exemplary embodiments, allocating the tasks may be biased to prefer allocating tasks to a first agent over a second agent, if an estimated quality of the first agent is greater than an estimated quality of the second agent. The biasing may not dependent on prior knowledge of the actual qualities of the agents.
In Step 150, an indication that the agent has completed the task may be obtained. In response to the indication, a reward, in Step 160 may be computed. The reward may be calculated according to a total contribution of the agent to the system by completing the task.
In some exemplary embodiments, the reward may be monotone in a quantity of the total contribution of the agent to the system. In some exemplary embodiments, the reward may be linear with the total contribution of the agent to the system. In some exemplary embodiments, the reward may be computed as a linear function of a total contribution of the agent to the system. The total contribution of agent i to the system, denoted u(i), may be calculated based on the following formula: u(i)=Σj(i)vj.

In some exemplary embodiments, the computerized system 200 may comprise a Tasks Pool 210, such as retained by a storage device. Tasks Pool 210 may comprise tasks that are generated by a multi-task system. In some cases, the system may continuously populate new tasks and store them in Tasks Pool 210 to be dispatched to agents, in accordance with the disclosed subject matter. In some exemplary embodiments, there may be different types of tasks. In some cases, different agents may be associated with performing different types of tasks. Additionally or alternatively, the competency of an agent may be different with respect to different types of tasks. As an example, one agent may be have high quality with respect to tasks of a first type (e.g., completes tasks of the first type with an average high quality), while the same agent may have a low quality with respect to tasks of a second type.
In some exemplary embodiments, an Agents Pool 220 may retain a list of agents that can perform the tasks. In some cases, Agents Pool 220 may comprise all agents that are registered with the system. Additionally or alternatively, Agents Pool 220 may comprise all active agents of the system, such as but not limited to agents that are currently willing and able to perform tasks. As an example, Agents Pool 220 may be updated in accordance with a status of each agent. In some exemplary embodiments, only agents that are currently connected to the multi-task system may be considered as active agents, as they can receive a task. In some exemplary embodiments, the agents may register when requesting to be assigned with a task, and Agents Pool 220 may comprise only those agents who registered accordingly.
In some exemplary embodiments, an Average Quality Estimator 230 may be configured to compute an average quality of tasks in the system that were completed in the past by an agent. In some exemplary embodiments, Average Quality Estimator 230 may be used to compute the average quality with respect to each agent in Agents Pool 220. In some exemplary embodiments, Average Quality Estimator 230 may compute the average quality of tasks in the system that were completed in the past by an agent by dividing a summation of contributions to the system of tasks completed in the past by the agent, by a number of tasks in the system that were performed in the past by the agent. The contributions to the system of tasks completed in the past by an agent may be provided, directly or indirectly, by a Quality Estimator 270. In some exemplary embodiments, the computation may be based on all historic data or based on data that was obtained within a predetermined timeframe, such as in last month, the last year, the last day, or the like. Additionally or alternatively, the computation may be performed based only of tasks of the same type as a target task that is to be dispatched (e.g., by a Probabilistic Agent Dispatcher 250).
In some exemplary embodiments, Quality Estimator 270 may be configured to estimate a quality of a task performed by an agent in the system. The quality may be estimated based on various factors, such as the time required to complete the task, the contribution of the task to the system, the results of the task, or the like. In some exemplary embodiments, the quality of a task is estimated upon its completion. The quality may be then be retained in a data storage (not shown) to be used in the future as part of the computations of Average Quality Estimator 230 that rely on tasks that were completed in the past. In some exemplary embodiments, the quality is retained together with an identifier of the agent that completed the task. Additionally or alternatively, the quality is retained together with a time stamp indicating a time of completion. Additionally or alternatively, the quality is retained together with a type of task.
In some exemplary embodiments, Probabilistic Agent Dispatcher 250 may be configured to select an agent from Agents Pool 220 to perform a task from Tasks Pool 210. Probabilistic Agent Dispatcher 250 may select the agent based on the average quality of the agent, estimated by Average Quality Estimator 230, and optionally for the same type of tasks as the task to be dispatched. In some exemplary embodiment, Probabilistic Agent Dispatcher 250 may allocate the tasks based on a probabilistic selection of an agent to perform the task. The probabilistic selection may be based on a set of probabilities, each of which is associated with an agent from Agents Pool 220. The probability to select an agent may be based on an average quality of the agent. In some exemplary embodiment, Probabilistic Agent Dispatcher 250 may apply a probabilistic regret minimization algorithm to select agents to perform the tasks.
In some exemplary embodiments, a Reward Manager 240 may be configured to compute a reward for an agent, in response to obtaining an indication that the agent has completed the task that the agent was allocated to perform. Reward Manager 240 may calculate the reward according to the total contribution of the agent to the system by completing the task. The reward may be provided to the agent to incentivize the agent to continue contributing to the system. In some exemplary embodiments, Reward Manager 240 may compute a reward for an agent in a batch process by processing a total reward for more than one task completed by the agent and for which the agent was not yet rewarded. Reward Manager 240 may output the reward to another entity to provide the reward to the agent, such as a bookkeeping department. Additionally or alternatively, Reward Manager 240 may provide the reward to the agent, such as by increasing the credits balance in an account of the agent.
In some exemplary embodiments, Reward Manager 240 may calculate the reward r(i) for agent i based on the following formula: r(i)=f·Σj(i)vj. In some exemplary embodiments, vj may be the quality of task j performed by agent i. vj may be calculated by Quality Estimator 270. Σj(j)vj may be a summation of vj for all tasks j that are performed by agent i. f may be a parameter, such as a constant value, a parameter value set by the user or defined based on configurations or preferences. Additionally or alternatively, the value of f may be automatically computed by Reward Manager 240, as is explained further hereinbelow.
In some exemplary embodiments, a Total Performance Estimator 260 may be configured to evaluate the total performance of the system. In some exemplary embodiments, the total performance of the system may be calculated based on the system's gain. The system's gain may be calculated based on the quality of the tasks completed in the system in the past. Additionally or alternatively, the system's gain may be calculated based on the average quality of agents performing tasks in the system.
In some exemplary embodiments, Total Performance Estimator 260 may calculate the total performance of the system based on the following formula: (1−f)·Σini·q1. In some exemplary embodiments, qi may be the average quality of agent i such as calculated by Average Quality Estimator 230. ni may be the number of tasks performed by agent i in the system. f may be the parameter used by Reward Manager 240 in calculating the rewards. f may be chosen by the system in order to optimize the total performance of the system. In some exemplary embodiments, the system may choose a value of parameter f that optimizes the system's gain. In some exemplary embodiments, the system may choose a value of parameter f by an optimization algorithm such as gradient descent method or the like.
In some exemplary embodiments, the difference between the optimal quality and the expected quality of a system in accordance with the disclosed subject matter may be bounded by
where N is the number of tasks performed by the system so far.
Referring now to
A prototype of a system in accordance with the disclosed subject matter was devised and simulated. The prototype simulated a stochastic system where tasks are dispatched to agents without the system having prior knowledge of the quality of the agents.
In the simulation there are 30 agents having different capabilities as shown in
The simulation dispatched 8000 tasks to the 30 agents.
The chart illustrated in
The chart illustrated in
When comparing these results with those that would have been received with a random agent selection, the overall gain of the prototype is about 35%. If an hypothetical algorithm in which all tasks are always dispatched to the best agent is simulated (i.e., optimal quality of the system), the gain of that system over the random selection would be 60%. Hence, the 35% improvement provided by the prototype provides a substantial improvement in compression to the random agent selection algorithm.
