Cold start
Alterra Answers contains a full-fledged knowledge base search engine
and thus is functional even if no training corpus is available. You may launch
it without any training. The users will come and the bot will record their queries.
You would label them later, using FAQ Editor.
Note
that without training the quality is lower. It typically starts with precision@1
at around 50%. As you add queries to the training corpus it quickly goes up to
~90%. Typically, 10 queries per article are enough to reach it.
