This article is a three-page short article that introduces a mobile-based crowdsourcing platform (mobileworks): for low-income areas, complete simple crowdsourcing tasks on your mobile phone (OCR tasks are used as pilot deployment in this article ).

 

The following are some excerpts:

1. mobileworks is divided into three main modules: (1) preprocessing: dividing tasks into blocks; (2) a UI enables workers to perform OCR tasks; (3) Post-processing: the segmented OCR task after the reorganization is completed.

2. Quality control: each task is assigned to two persons and must be matched before it passes.

3. An experiment was conducted in two cities in India to obtain the accuracy data: 89% (not considering redundancy) and 98.79% (dual entry accuracy ).

4. Improvement Direction: (1) Deploy other tasks. (2) Support for real-time response

5. Other information of interest: mturk had 0.2 million workers last month, mainly distributed in the United States (56%) and India (36% ).
