VIRET tool keyword search at TRECVID 2019 AVS task

This paper presents details of a frame-based keyword search component that was used for TRECVID 2019 Ad-hoc Video Search with manually-assisted querying. The component is part of the VIRET framework primarily developed for interactive known-item search. For each task one query was formulated and the query was used to form four dierent runs by applying dierent scoring functions.
