CrowdFill: collecting structured data from the crowd

摘要: We present CrowdFill, a system for collecting structured data from the crowd. While typical microtask-based approach would pose specific questions to each worker and assemble answers, CrowdFill shows partially-filled table all participating workers. Workers contribute by filling in empty cells, as well upvoting downvoting entered other The system's synchronization scheme, based on careful model of primitive operations, enables workers collaboratively complete without latency overhead. allows specification constraints collected data, has mechanisms resolving inconsistencies. Its compensation scheme takes into account worker's contribution final table, varying difficulty entry tasks. paper includes some preliminary experimental results.
