Dr. Eoin Hurrell discusses NLP applications in search at Cohort. Cohort helps users find relevant people in their network they could get an introduction to from a close friend. Cohort classifies social media posts as "asks" or searches, and uses techniques like part-of-speech tagging and word vectors trained on technical data to understand the concepts in asks and expand the scope of searches to return more relevant results. Evaluation of understanding concepts in 542 real asks achieved an F1-score of 87.06%. Currently, Cohort uses a more explicit exploratory search interface and word vectors to enrich information searched over.
