I spent too much time trying to parse the meaning of this headline. I wish HN would train a regressor for the difficulty in understanding a headline's meaning, and then automatically restrict them past some threshold.
[1] A garden-path sentence is one where you find at the end that the expected parsing is wrong. e.g. "The old man the boat" or "The horse raced past the barn fell". https://en.wikipedia.org/wiki/Garden-path_sentence
It's a bad headline. There's no a complete sentence here. "DOJ vs. Google evidence release" is a noun phrase ("release" here is used as a noun), modified by the clause "that judge calls embarrassing exhibit". In that clause, "judge" is the subject, "calls" is the verb, "that" is the direct object, and "embarrassing exhibit" is an object compliment, which refers to the same thing as "that". So basically we just have a big noun phrase.
Is it really that difficult?
