表7.29において，提案手法は原文を選出している．しかし，表7.30より，原文に対する出力文よりも，主語補完を行った文の方が翻訳品質が高い．よって，提案手法の選出が誤りである．
次に，2つ目の文を表7.31に示し，提案手法の翻訳候補及び翻訳確率を表7.32に示す．

表7.31において，提案手法は``彼らは"を補完した文に対する出力文を選出している．しかし，表7.32より，主語として``私は"を補完した文に対する出力文の方が翻訳品質が高い．よって，提案手法の選出が誤りである．
以上のように，提案手法の選出の誤りが，200文中2文存在した．選出の誤りの事例は少数ではあるが，選出の性能を向上することで，さらに翻訳精度は向上すると考える．
