named entity recognition
How a model extracts people, organisations, places and products from unmarked prose when no structured data exists. It is why a page with no schema is still partly understood, and why structured data is an advantage rather than a requirement.
What named entity recognition does not show
What it cannot give is a stable identity: a name found in text is a string, matched by guess to whichever entity seems likeliest, and two organisations with similar names are confused exactly where a stable @id would have separated them.
