Summary

Evaluation

The author evaluate CLMM's performance using [MPQA] and [NTCIR] in mainly two cases:

1) Keep the labeled data in target language (Chinese) unavailable.

A

2) Using the labeled target language (Chinese) data.

B

Discussion

The author provides an analysis (entropy estimates along with upper-bound numbers observed from experiments) and suggests that there can be interesting future work to explore the contextual information provided by the stimulus more effectively and further improve the response completion task.
