Exploring the importance of context and embeddings in neural NER models for task-oriented dialogue systems

6 Dec 2018Pratik JayaraoChirag JainAman Srivastava

Named Entity Recognition (NER), a classic sequence labelling task, is an essential component of natural language understanding (NLU) systems in task-oriented dialog systems for slot filling. For well over a decade, different methods from lookup using gazetteers and domain ontology, classifiers over handcrafted features to end-to-end systems involving neural network architectures have been evaluated mostly in language-independent non-conversational settings...
