The power of crowdsourcing has dramatically shortened the required time to create accessible content for disabled people with high quality. A number of existing crowdsourcing projects for accessibility use human-machine hybrid systems, where a computer processes the input and human workers correct the output if it is wrong. However, some workers overlook the incorrect output or corrupt the correct one for various reasons, which lower the quality of the final corrected results. Therefore, a quality control method taking account of these workers' behaviors is needed for higher-quality content. This paper proposes a novel statistical model that describes the influence of the machine output on how the workers react, along with an algorithm that infers the correct results from the efforts of the workers. Our experimental evaluations with synthetic and real datasets demonstrate that the proposed method can decrease the number of correction errors compared to the existing methods. |
