As showed in Table II, there are at most 56 tags for a
watched media, while this value increase to 90 from all
database objects. From percentiles, we can observe that only
a small portion of database objects have more than 54 tags.
Figure 5 demonstrates that the majority of medias (about
90%) have less than 10 tags. However, the number of videos
with less tags is higher from database medias than the
watched ones.
