The Enron dataset pivot story is wild! PhD projects always seem to turn into building the tools you wish existed. I totally feel the pain of custom parsers failing on messy data. We process millions of social media posts for influencer analysis and the format inconsistencies are a nightmare. RegEx works until it spectacularly doesn't. Quick question though - how does it handle really domain-specific annotation tasks? Like if I need to extract sentiment and engagement metrics from Instagram comments in different languages, can it adapt to those custom categories pretty easily?
