May I Ask Who's Calling? Named Entity Recognition on Call Center Transcripts for Privacy Law Compliance

We investigate using Named Entity Recognition on a new type of user-generated\ntext: a call center conversation. These conversations combine problems from\nspontaneous speech with problems novel to conversational Automated Speech\nRecognition, including incorrect recognition, alongside other common problems\nfrom noisy user-generated text. Using our own corpus with new annotations,\ntraining custom contextual string embeddings, and applying a BiLSTM-CRF, we\nmatch state-of-the-art results on our novel task.\n
