The extreme multi-label classification (XMC) task aims at tagging content
with a subset of labels from an extremely large label set. The label vocabulary
is typically defined in advance by domain experts and assumed to capture all
necessary tags. However in real world scenarios this label set, although large,
is often incomplete and experts frequently need to refine it. To develop
systems that simplify this process, we introduce the task of open vocabulary
XMC (OXMC): given a piece of content, …
