Active Learning and Crowdsourcing: A Survey of Optimization Methods for Data Labeling

详细

High-quality annotated collections are a key element in constructing systems that use machine learning. In most cases, these collections are created through manual labeling, which is expensive and tedious for annotators. To optimize data labeling, a number of methods using active learning and crowdsourcing were proposed. This paper provides a survey of currently available approaches, discusses their combined use, and describes existing software systems designed to facilitate the data labeling process.
