PitchBook Natural Language Search (NLS) is a general search experience improvement solution with natural language understanding. Currently the PitchBook platform requires selecting from more than 50 criteria checkboxes in advanced search for precise company searches. With our advanced NLP framework, this solution enables users to use a sentence to search for companies fast and efficiently. The NLS general search dashboard fetches targeted criteria based on a single sentence user typed in, and returns identified criteria and relevant company results from database. This project aims to improve user search experience and explore more AI possibilities for PitchBook in the long term.
