Usually, a trade-off between precision and coverage is hard to find, and it depends on the methodology used to build the lexicon. Manually annotated lexica provide a high precision but lack in coverage, whereas automatic derivation from pre-existing knowledge guarantees high coverage at the cost of a lower precision. Since the automatic derivation of prior polarities is less time consuming than manual annotation, there has been a great bloo","authors_text":"Lorenzo Gatti, Marco Guerini, Marco Turchi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2015-10-30T13:19:47Z","title":"SentiWords: Deriving a High Precision and High Coverage Lexicon for Sentiment Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1510.09079","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:b7a33c46d1322dda96fdae3fbd00fe48b032c1df01cce68c136929c592393c94","target":"record","created_at":"2026-05-18T01:28:23Z","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":"4e563bfa5118206e7709a9946dd3e8113f45710687867ef5d98587eadbba419d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2015-10-30T13:19:47Z","title_canon_sha256":"7d87606846ca2a689c90eeb07b6f1362d6315ba6ae22a09a4a7a12f52124992e"},"schema_version":"1.0","source":{"id":"1510.09079","kind":"arxiv","version":1}},"canonical_sha256":"cc29b3648926c452c9a4011827753d0d3d9f03bcfb91f7048c6413b62854bd4a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cc29b3648926c452c9a4011827753d0d3d9f03bcfb91f7048c6413b62854bd4a","first_computed_at":"2026-05-18T01:28:23.226886Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:28:23.226886Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4URhbnlF167DhnIm/6QNhD4xyB3TS+S7JfROjs+rnllnLxZjf50f40axLNnLiwOMgT6G3uvu/d2KJ8CZfb4sAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:28:23.227559Z","signed_message":"canonical_sha256_bytes"},"source_id":"1510.09079","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b7a33c46d1322dda96fdae3fbd00fe48b032c1df01cce68c136929c592393c94","sha256:b9c928f6bc17c0525b99b2f5eb6f55c5a27e657bc722d0596ce4207eb9956eaf"],"state_sha256":"f390c32c4123c8b5d5d31602076a49f2538d8efbf67ac3d80b68d01a220d9574"}
