I built an API that extracts entities from Hacker News comments and classifies sentiment towards them as positive, negative, or neutral. It also classifies overall comment sentiment and assigns each entity a label (person, location, date, technology, organization, other).505k+ comments, Oct 31 - Present.Here's the leaderboard:LOVED:- Steve Jobs: 44% positive, 7% negative- Linus Torvalds: 43% positive, 5% negative- Gabe Newell: 34% positive, 8% negativeMID:- Bill Gates: 22% positive, 8% negative- Tim Cook: 15% positive, 30% negative- Bezos: 12% positive, 18% negativeHATED:- Zuckerberg: 4% positive, 35% negative- Sam Altman: 8% positive, 38% negative- Musk: 5% positive, 45% negativeTry it yourself:# Who does HN talk about the most?curl "https://api.hnpulse.com/entities?label=person&sort=mentions"# What are people saying about remote work?curl "https://api.hnpulse.com/comments?entity=remote work&limit=3"# Is OpenAI's reputation getting worse?curl "https://api.hnpulse.com/trends?entity=openai&bucket=day"# What technology gets mentioned alongside SF?curl "https://api.hnpulse.com/entities?co-occur=SF&label=technolog..."Stack: Go, PostgreSQL, GPT-4o mini for entity extractionDocs: https://docs.hnpulse.com API: https://api.hnpulse.com

Could you build this?
Yes The product extracts entities and sentiment from public comments via standard batch processing or off-the-shelf NER/sentiment models (or LLM API calls) and serves the results over a REST API.
Discussion
9 comments analyzed.
Concerns raised: Cost is high - $238.21 and 663M tokens for analysis, Binary sentiment analysis loses nuance between different types of criticism, Data collection and annotation effort required for personal datasets
Feature requests: AI nudging for better communication patterns in personal comments, More granular sentiment analysis beyond binary positive/negative, Easier personal data collection from Chrome bookmarks and social posts
