Abstract：Many truth inference methods have been proposed to improve crowdsourcing quality and to obtain high-quality annotated data. Traditional truth inference uses multiple noisy labels as inputs to deduce the real labels through an aggregation strategy. This paper introduces the features of the instances that most effectively mine the useful information contained in the instances. The probability that a crowdsourcing instance belongs to each category is used to divide the crowd-sourcing dataset. An integrated meta-learning classifier is trained on the new dataset to calculate a similarity degree to get worker weights that show each worker's annotation ability for different instances. Finally, a weighted soft voting method is used to predict the labels. Tests show that this method is superior to existing truth inference algorithms for public and constructed datasets.
