Domain-Adapt an NLP Pipeline from News to Customer-Support Tickets
Overview
What this challenge is about.
You receive 30,000 anonymized customer-support tickets (PT-BR + ES) plus the news-trained NER and intent models. Apply continued pretraining of a multilingual encoder (e.g., XLM-RoBERTa-base) on the ticket corpus, then fine-tune the two downstream tasks. Compare against (a) the news-only baseline and (b) fine-tune without continued pretraining. Report per-language entity F1, intent accuracy, and an honest discussion of where domain adaptation helps and hurts. Deliver a 3-page recommendation memo for the head of NLP.
The Brief
What you'll do, and what you'll demonstrate.
Quantify how much continued pretraining + fine-tuning beats fine-tuning alone for NER + intent on multilingual customer-support tickets.
Earning criteria — what you'll demonstrate
- Apply continued pretraining of a multilingual encoder on a domain corpus
- Fine-tune downstream NLP tasks and compare against meaningful baselines
- Reason about positive and negative effects of domain adaptation
- Communicate domain-adaptation cost vs. benefit to a product-NLP audience
