Google is using old news reports and AI to predict flash floods
What Happened
A new way to solve data scarcity: Turning qualitative reports into quantitative data with an LLM.
Our Take
This is good engineering. Google scraped old news reports about floods, used an LLM to extract structured data (time, location, severity), then fed that into ML models. Solved a real problem—data scarcity in developing countries.
No massive labeled dataset, no years of sensor deployment. Just 'we have text, let's make it data.' More teams should think like this instead of waiting for perfect data.
Only caveat: accuracy probably isn't great (news reports are inconsistent), but it's better than nothing. If this prevents even one false negative, it's worth it. This is the one that actually ships.
What To Do
Use LLMs to extract structure from unstructured historical data when labeled datasets don't exist.
