The paper is devoted to the construction and expansion of such linguistic resources as dictionaries and thesauri using microtask-based crowdsourcing. Approaches for microtask complexity estimation, worker ranking, and adaptive task assignment are discussed. The implementation of these approaches is available in a software system designed using the three-tier architecture.
