In this work, we propose an unsupervised \\emph{tri-clustering} framework, which analyzes both user-level and tweet-level sentiments through co-clustering of a tripartite graph. A compelling feature of the proposed framework is that the quality of sentiment clustering of tweets, users, and features can be mutually improved by joint clustering. We further investigate the evolution of user-level sentiments and l","authors_text":"Aram Galstyan, James Cheng, Kristina Lerman, Linhong Zhu","cross_cats":["cs.CL","cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2014-02-24T22:58:28Z","title":"Tripartite Graph Clustering for Dynamic Sentiment Analysis on Social Media"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.6010","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:cfc484e2fa828b1c69c81e9dc4b1f82387df41d0b0e7e6cc3331e544a9b619a7","target":"record","created_at":"2026-05-18T02:49:53Z","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":"8985348bb2bd1b814c386f684cafc91a63c5ff4fbd879dc7def9d7ae7ad9b0ce","cross_cats_sorted":["cs.CL","cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2014-02-24T22:58:28Z","title_canon_sha256":"cf1f13a5ba5f0a7e00a40e100d10acf02759d6c1d1879ef33a5b26ca8c58fe88"},"schema_version":"1.0","source":{"id":"1402.6010","kind":"arxiv","version":3}},"canonical_sha256":"8dc1140fe4592a0e56e97f2dcdeebbcec447a71f5002710fc826ba6f00fd9be3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8dc1140fe4592a0e56e97f2dcdeebbcec447a71f5002710fc826ba6f00fd9be3","first_computed_at":"2026-05-18T02:49:53.604051Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:49:53.604051Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"piwvN1wYwJJ2/tLbq82MVq0tDEQJLDNMnsFZzdrPuSSdk94I9Pd3zjZ0Btxdr3lc5ok7R8m7KWZRD2vFiaWHBg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:49:53.604680Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.6010","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cfc484e2fa828b1c69c81e9dc4b1f82387df41d0b0e7e6cc3331e544a9b619a7","sha256:52f3944dfe816be42b412766784e5c38a0fe5ecc908056a64e5de5d425267ad8"],"state_sha256":"57606129530fe0b3492f71314057cad3c7ed11110ff3d7303606a364492b97ef"}
