data structures and pipeline • build support for new tasks even if we don’t have a model • make sure it's easy to BYO model • keep shipping good defaults What’s out-of-scope? • anything generative: summarization, machine translation, etc. • multi-modal: audio, video, etc. • research assistance: plenty of good frameworks for developing novel techniques • morphological features • entity linking • non-entity span tagging • static analysis of processing pipeline and its components
