The email from the lawyer might mention lots of names. Who are the plaintiffs, who are defendants, their attorneys, assistants, or insurance adjusters. The model parses out who is who and connects names to titles to email addresses.

Interesting, that's what I thought it meant, but didn't realize it was a term of art.

Things like inferring the meaning of “people parsing” when it isn’t explicitly defined but can be implied by context.

Not strict rational A+B=C, nuance.
