The Waseda Meisei SoftBank team participated in the TRECVID 2019 Ad-hoc Video Search (AVS) task [1]. For this year's AVS task, we submitted both manually assisted and fully automatic runs. Our approach consisted of concept-based video retrieval for manually assisted runs and visual-semantic embedding for fully automatic runs. Our best manually assisted run achieved a mean average precision (mAP) of 15.2%, which ranked the highest among all the manually assisted systems. Our fully automatic run achieved an mAP of 12.3%, which ranked third among all participants.
