The Treato platform is built on a technological process that identifies, collects, analyzes, indexes, and aggregates UGC. Scalability of the system is critical in responding to the challenge of the continuously growing number of pages and increasing volumes of health-related data on the web. Treato is powered by CDH. To date, Treato has aggregated and analyzed more than 1.1 billion online posts about over 11,000 medications and over 13,000 conditions from thousands of English language websites. The system can currently process 150-200 million user posts per day.
