Abstract: Particular embodiments may receive, by one or more processors of an information processing system, results of one or more tasks performed by a worker. The volume of the results for one of the tasks may be determined to be insufficient. The volume of the results of similar tasks completed by the worker may be determined to be sufficient. A weighted similarity score may be assigned based on the results of the similar tasks completed by the worker.

Abstract: In one embodiment, a method for providing recommendations for workflow alteration is disclosed. Task results for completion of a first set of iterations of a workflow are received. Training data may be extracted from the task results. The training data may be used to build a machine learning model for altering at least a portion of the workflow. An automation forecast that assesses the effects of altering the workflow for a second set of the iterations of the task may be generated, and a workflow alteration recommendation may be provided. Based on automation parameters, such as a minimum required level of accuracy, and the automation forecast, a recommendation regarding whether to automate the task may be included in the workflow alteration recommendation. Finally, based on the recommendation, an automated process may be generated to handle at least a portion of the task.

Abstract: In one or more embodiments, one or more methods, processes, and/or systems may receive data associated with effective completion of tasks by agents and determine a positive correlation within the data between first particular feature values of feature vectors associated with the tasks and second particular feature values of feature vectors associated with the agents. A first agent associated with a feature vector that matches, within a first threshold, the second particular feature values may be selected, and a probability that the first agent will effectively complete a first task based on a feature vector associated with the first task matching, within a second threshold, the first particular feature values may be determined.

Abstract: Particular embodiments may receive, by one or more processors of an information processing system, results of a benchmark task performed by a set of one or more workers.

Abstract: Particular embodiments may receive, by one or more processors of an information processing system, results from completion of a plurality of iterations of a task performed by a worker. The volume of the results for the worker may be determined to be insufficient. A set of similar workers may be identified, wherein each of the similar workers has a sufficient volume of results for the task. A weighted score of similarity between the worker and the similar workers may be assigned based on the results of the task as completed by the similar workers. Estimates based on the weighted similarity score may be provided for the worker's behavior for the task.

Abstract: Particular embodiments may receive results from completion of a first set of a plurality of iterations of a workflow, the workflow comprising one or more tasks performed by one or more workers. A result for a task may be received from a worker. A fraud candidate model may be determined based on attributes of one or more confirmed instances of fraud assessment and a first vector of behavioral features of the worker. Particular embodiments may then determine whether the result is fraudulent based on the fraud candidate model.

Abstract: One or more embodiments manage web-based crowdsourcing of tasks to an unrelated group of workers. An information set associated with a task to be crowdsourced is received from at least one customer that is associated with the task. This information set comprises at least a description of the task, a reward to be provided for completion of the task, and at least one adjudication rule for accepting a task result. At least one advertising campaign for the task is created based on the information set. The advertising campaign is published for access by a set of one or more worker systems. At least one task result associated with the task is received from at least one of the set of one or more of the worker systems. The task result is compared against the rule. Task results are received and compared to the adjudication rule until the rule is satisfied.

Abstract: Positioning apparatus comprises: a first surface; a tubular body and a first end surface at a first end of the tubular body and arranged in contact with the first surface; and surface wave generation means arranged to generate a first travelling surface wave on the first end surface, the first travelling surface wave travelling along a first portion of the first end surface in a first direction, and, while the first travelling surface wave is travelling along the first end surface, to generate a second travelling surface wave on the first end surface, the second travelling surface wave travelling along a second portion of the first end surface in a second direction, the second direction being opposite to the first direction. Interaction between the first surface and the first and second travelling surface waves effects relative movement between the first surface and the tubular body.
