YouTravel: a YouTube LLM Engine

Search for Travel Narratives & Claims per country.

Description

Travel videos & vlogs are sometimes the best source of firsthand information for people interested in planning a trip or learning about a country. Using video transcripts from YouTube, we display overall trends, top narratives per country, and claims per video.

The Breakdown

  1. Batch Ingestion: Pick channels from the travel and lifestyle buckets. Download the transcript if available. Use OpenAI's Whisper to transcribe if needed
  2. LLM Feature Extraction: Parse the transcript to classify travel videos, and extract a structured set of narratives per-video with claims from the creators
  3. Risk Assessment: Use search and comments to detect sentiment spikes and potential false statements
  4. Top Narrative Clustering: Use an embedding model to convert narratives into vectors. Then HDBSCAN can return the top 3 semantic clusters of narratives per-country, per-creator, and overall.
