Wordnik’s goal is to gather words in context, and use the results in interesting and useful ways. Leading a seven person team to create lexical resources, manage the natural language processing pipeline, and develop content-based recommendation systems which also use social and personal signals. Also, leading the effort to apply evidence-based metrics for A/B testing for recommendation systems, etc.
