Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a kind of online pricing method based on mobile crowd sensing based on data quality, which specifically includes the following steps:

[0033] S1: Obtain a mobile crowd sensing task, the mobile crowd sensing task includes: task content, task budget, and quality requirements;

[0034] S2: Construct a Markov decision process model for the mobile crowd sensing task, select an initial price for the mobile crowd sensing task from the Markov decision process model, and publish it;

[0035] S3: Publishing the quality requirements of the mobile crowd sensing task according to the strategy based on the continuous Actor-Critic algorithm;

[0036] S4: Obtain the user's data quality and user's action selection, calculate the rewards obtained by recruiting users according to the Markov decision process model, and determine the recruitment results; if the reward is greater than zero, it means that the user has been recruited ...

Embodiment 2

[0078] Such as image 3 As shown, the present invention also provides a mobile crowd sensing online pricing system based on data quality: including a service platform 1 located in the cloud, a task provider 2 and a personal mobile terminal 3 that can be connected to the platform. It can be understood that the task provider 2 is used to send mobile crowdsensing tasks to the service platform 1, and obtain mobile crowdsensing data from the service platform 1; mobile crowdsensing data includes but not limited to text, pictures, printed matter, At least one of video and spatio-temporal information. The service platform 1 can accept the mobile crowdsensing task from the task provider. The mobile crowdsensing task includes: task content, task budget, and quality requirements; and releases the dynamic crowdsensing task to the personal mobile terminal 3 and conducts the dynamic crowdsensing task. Set the price, then recruit users, and feed back the mobile crowd sensing data completed ...

Abstract

The invention provides a mobile crowd sensing online pricing method and system based on data quality. The method comprises the steps of obtaining a mobile group sensing task; constructing a Markov decision-making process model for the mobile group sensing task, selecting an initial price of the mobile group sensing task from the Markov decision-making process model and publishing the initial price; issuing the quality requirements of the mobile group sensing task according to the strategy based on a continuous Actor-Critic algorithm; acquiring data quality and action selection of a user, calculating a reward obtained by recruiting the user according to the Markov decision-making process model, and determining a recruiting result; and according to the recruitment result and the Markov decision-making process model, transferring the bid price to the next price and waiting for the arrival of the next user until the budget is depleted or no more users come. Appropriate perception task participants are recruited, and the data quality is improved as much as possible to realize platform profit maximization.

Description

technical field [0001] The present invention relates to the technical field of mobile crowd sensing, in particular to a mobile crowd sensing online pricing method and system based on data quality. Background technique [0002] In recent years, mobile crowd sensing has provided a new modality for large-scale sensing tasks. With the rapid development and improvement of mobile terminal processors, memory and other hardware devices, the field of mobile devices has been prosperous and developed. Sensors such as cameras, microphones, GPS, gyroscopes, and accelerometers are embedded in smart mobile terminals represented by smartphones and tablets. , provides an efficient way to collect data. Therefore, many mobile crowd sensing applications have emerged, such as Amazon Mechanical Turk as an online crowdsourcing platform, VTrack provides traffic information through crowd sensing, and Sensorly is used to build cellular network / WiFi network coverage maps. [0003] In practical appli...
