ESTIMATION METHOD, ESTIMATION SYSTEM, COMPUTER SYSTEM, AND PROGRAM

PROBLEM TO BE SOLVED: To estimate the abilities of workers in processing for integrating work results performed by multiple workers.SOLUTION: An estimation method includes: a step S101 of acquiring for each of one or more tasks results oof work performed by workers in a former stage and results yof work performed by workers in a later stage on the basis of the results oby the workers in the former stage; and a step of estimating multiple parameters in a probability model, in which the abilities α,βof the workers in the later stage conditioned by the qualities of the results of work by the workers in the former stage are introduced as parameters, on the basis of the results o, yof the work obtained for each of the one or more tasks. Thus, the abilities of multiple workers in processing for integrating the results of work performed by the multiple workers for the same task are estimated.SELECTED DRAWING: Figure 5 【課題】 複数のワーカが行った作業結果を統合する処理におけるワーカの能力を推定すること。【解決手段】 本推定方法は、コンピュータ・システムが、１以上のタスク各々に関し、前段のワーカの作業結果ｏｔと、該前段のワーカの作業結果に基づいて作業する後段のワーカの作業結果ｙｉｔとを取得するステップＳ１０１と、上記１以上のタスク各々に関して得られた複数の作業結果ｏｔ，ｙｉｔに基づき、前段のワーカの作業結果の品質で条件付けられた後段のワーカの能力αｉ，βｉがパラメータとして導入された確率モデルの複数のパラメータを推定するステップとを含む。これにより、同一のタスクに関する複数のワーカの作業結果を統合する処理におけるワーカの能力を推定する。【選択図】 図５
