Leaderboards with results placed since the archive Syntology

The archive's leaderboards stopped at 2025-07-28. In this build Syntology placed 132 results from 93 newer papers on the 95 leaderboards below. On each leaderboard they are listed in a separate “Since the archive” section under the archive's rows, labelled Syntology, dated, and never ranked among the archive rows. A model pointed at the cell in the paper's own table, the number was read from that cell and checked against the leaderboard's metric, dataset, split and scale, and an independent check accepted it; none is reviewed by the paper's authors or by the archive's editors (how they were placed). Syntology has checked 8,886 of the 9,662 papers on this site that are newer than the archive (for 3,717 of them no archive leaderboard matched the paper's tables, so there was nothing further to check); 733 were read and have nothing to place (arXiv has no HTML version of the paper, or that version has no tables), 41 could not be read (the extractor's reply could not be parsed), and results from the other 2 appear after they are checked. Measured before publishing, on held-out archive papers: the extractor was given 883 of them and produced output for 881 (the other 2 had no title and were excluded before any model call, so they are not part of this measurement). A model adjudicator (Claude Opus 5.5), blind to which entries were real, judged 108 of 110 accepted entries correct on those held-out archive papers; its own controls: 69 of 70 archive-confirmed entries judged true, 101 of 103 corrupted copies judged false. It was not measured on the newer papers whose results are placed on this site.

Order: newest placed paper first (its arXiv date, else the month in its arXiv id), then task, then dataset. “Placed entries” counts one entry per paper per leaderboard; “Archive rows” is the leaderboard's own row count at the snapshot archive 2025-07-28. Every leaderboard the extractor proposed and did not place is counted on what is not shown; the same list is at /placed.json.
