Capturing Human Factors to Optimize Crowdsourced Label Acquisition through Active Learning

Senjuti Basu Roy
2019 IEEE Data Engineering Bulletin  
Our basic approach is to take a set of existing active learning techniques for a few well known supervised and unsupervised algorithms, but study them in the context of crowdsourcing, especially considering  ...  The goal of this article is to propose an optimization framework by acknowledging human factors to enable label acquisition through active learning .  ...  The closest related works for active learning through crowdsourcing are for single label acquisition [64, 62, 41, 16, 18] . Worker-centric optimization is not considered there.  ...

FROG: A Fast and Reliable Crowdsourcing Framework (Technical Report) [article]

Peng Cheng, Xiang Lian, Xun Jian, Lei Chen
2018 arXiv   pre-print
For the task scheduler module, we formalize a FROG task scheduling (FROG-TS) problem, in which the server actively assigns workers with tasks with high reliability and low latency.  ...  For decades, the crowdsourcing has gained much attention from both academia and industry, which outsources a number of tasks to human workers.  ...  For the subjective tasks, such as image labeling, translation and knowledge acquisition, we may use other data mining or machine learning methods [31] , [14] to estimate their difficulties.  ...
