Paul Berry is the CTO of Huffington Post. The Huffington Post uses semantic technology in a few areas, and the use of semantic tech has had a significant positive effect on the Post, allowing it to grow rapidly and still maintain an effective editorial oversight for its steady stream of reader commentary.

- The Post has a custom built comments application paired with a moderation component. Their analysis goes beyond simple "bad words", and uses semantic analysis to review and categorize comments that may need human moderation.

- Their investment in the company Adaptive Semantics brings advanced semantic analysis of comments directly into the workflow.

- The use of semantics has enabled Huffington Post to grow from 3,000 comments per day to more than 90,000 comments per day.

- Developing applications to find 'sentiment' on comments and blog posts using semantics.
