# Citation Telephone

TypeSafe released Citation Telephone, a free tool that takes a cited sentence, opens the papers it cites one by one, finds the passage the sentence rests on, and labels each hop as matching, partly matching, going further or changed. On a held-out third set of 39 full-text citation pairs it found a supporting passage in 38 (97%) and reported support in 0 of 21 pairs where reviewers judged the paper did not state the claim; but hop labels agreed with reviewers in only 47% to 55% of pairs, so a warning should be treated as a reason to read the passage yourself.
