Existing approaches typically rely on data preprocessing pipelines that retain either compact or extensive table content as contextual evidence, and then formulate entity linking as a language generation task for instruction-tuned models; recent systems further incorporate explicit reasoning to disambiguate challenging mentions. However, their training supervision is usually static: fixed preference data cannot adapt to the residual errors of an evolving model, while variations in","authors_text":"Kehao Li, Stefan Decker, Yixin Peng","cross_cats":["cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CL","submitted_at":"2026-07-29T18:08:26Z","title":"TELLER: Dual-Path Iterative Preference Optimization for Table Entity Linking"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.28680","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:7ef6f1d7d43f2a23219e4db33b9a20d0398b668eab2bf31bc8746ca354a6fb39","target":"record","created_at":"2026-08-03T00:12:09Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"390b78b3dc9a9b6b221fe9645d18c5561a8edb8ea627cbe00cdacfc6fab4adb2","cross_cats_sorted":["cs.LG"],"license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.CL","submitted_at":"2026-07-29T18:08:26Z","title_canon_sha256":"820da47eeb5b11a673fddb4e5e159c027ccfff2b6574c875b015b6aa3747f229"},"schema_version":"1.0","source":{"id":"2607.28680","kind":"arxiv","version":1}},"canonical_sha256":"3efa2d5b7e80831c2553f7f602f624b1e4ecab942201a6cb8f58b64f86aa53cf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3efa2d5b7e80831c2553f7f602f624b1e4ecab942201a6cb8f58b64f86aa53cf","first_computed_at":"2026-08-03T00:12:09.593238Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-03T00:12:09.593238Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ECVZgUhyqMwTHCb4H8T6WbyhVDh7A+7eRhaESJwySu2J6aZ4PeK0lHabdtGUCwlUs9AC97V6kp8HSRfh1zHiBw==","signature_status":"signed_v1","signed_at":"2026-08-03T00:12:09.595227Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.28680","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7ef6f1d7d43f2a23219e4db33b9a20d0398b668eab2bf31bc8746ca354a6fb39","sha256:ca645ebdc94375fce616851d0ebaaa1205dce82008a256ab4866843ba1b34c0f"],"state_sha256":"333871a95fe7adb4b8e50342ef1bfcf1f3bf57ca6f7ced3683034c907bc83f4b"}
