Its success stems from being a modified pre-trained multilingual model finetuned for quality assessment. However, it being a machine learning model also gives rise to a new set of pitfalls that may not be widely known. We investigate these unexpected behaviours from three aspects: 1) technical: obsolete software versions and compute precision; 2) data: empty content, language mismatch, and translationese at test time as well as distribution and do","authors_text":"Barry Haddow, Nikita Moghe, Pinzhen Chen, Tsz Kin Lam, Vil\\'em Zouhar","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2024-08-27T19:03:11Z","title":"Pitfalls and Outlooks in Using COMET"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2408.15366","kind":"arxiv","version":3},"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":"sha256:57f7c9df53fdcef2e93e4c421c7806dda8ead7c096400aedbf248882e09b95c7","target":"record","created_at":"2026-07-05T09:13:38Z","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":"9a72ea3ced3ee2cdf5fdbb53859b634fafc7e3a6f0e3060d7167f542aa389995","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2024-08-27T19:03:11Z","title_canon_sha256":"5906a06639537eda17f305bceba45f06db4b05f58dde2f727ab8b26b680876ba"},"schema_version":"1.0","source":{"id":"2408.15366","kind":"arxiv","version":3}},"canonical_sha256":"406871fef585c7a092850e597f3a322495e52bc846fd47318cf775427afb7779","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"406871fef585c7a092850e597f3a322495e52bc846fd47318cf775427afb7779","first_computed_at":"2026-07-05T09:13:38.342754Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:13:38.342754Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iqxOyCcTYG4dycE/5nNymJV6PZ5Se3kNlm+2rF3/Puzj+I8VOeN7wIT7cgrd/QMMSjJl9ouF51BuEZO3RTntAA==","signature_status":"signed_v1","signed_at":"2026-07-05T09:13:38.343243Z","signed_message":"canonical_sha256_bytes"},"source_id":"2408.15366","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:57f7c9df53fdcef2e93e4c421c7806dda8ead7c096400aedbf248882e09b95c7","sha256:a452a24f268ebe4161abab211b0a8b8248b56b7aca5f335affbe2387bccee7d1"],"state_sha256":"b49c08f88f3870946e6a0e6f7854a1923277ed5282eefbfc202d8a2d25576bce"}
