Already in the database, but barely extracted.
Each paper below is in the database but yielded fewer than 5 extracted facts. That almost always means we only ever parsed an abstract, or the extraction run failed partway — not that the paper is thin.
A full-text submission for one of these is worth more than a new paper: it fills a hole we already know about. Pick one, run the parser over the full PDF, and hit Contribute this paper — the form arrives pre-filled with everything we already know.
