I've never heard of NLP model accuracy deteriorating over time, and a Google search hasn't yielded anything relevant. Is there a source about this you could point me to?

Hey, so this typically happens when there is a change in vocabulary. Just sharing my experience of facing this issue, we built a chatbot to answer product onboarding queries and with a new marketing campaign, we got a great influx of younger audience. Their questions were generally accompanied with a lot of urban slang and emojis which our NLP model wasn't equipped to handle, causing the performance to deteriorate.
