Figure 1 shows the T_Precision curve and Figure 2 shows the T_Recall curve when varying the value of n. It turned out that LM and W2V have about 80% and 90% of T_Precision within the top five candidates respectively, which means a large portion of the targets that are assigned any candidates of CEFR-LS have at least one correct candidate in the top five words.
it can be said that W2V outperforms LM in that it finds a correct answer more quickly (60% T_Precision for the top-ranked word).
