Our model simultaneously identifies an underlying set of ratable aspects presented in the reviews of a product (e.g., sushi and miso for a Japanese restaurant) and determines the corresponding sentiment of each aspect.  This approach directly enables discovery of highly-rated or inconsistent aspects of a product.  Our generative model admits an efficient variational mean-field inference algorithm.  It is also easily extensible, and we describe several modifications and their ef","authors_text":"Christina Sauper, Regina Barzilay","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2014-01-23T02:48:07Z","title":"Automatic Aggregation by Joint Modeling of Aspects and Values"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.6422","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":"sha256:0a5ddbd4c2b5788ae597a92e0bc59b7ded355ebcfd1a8503dfe6dedac948c34e","target":"record","created_at":"2026-05-18T03:01:12Z","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":"1894649a57b81b623c1e82e85bae69910e2e773fb391f9df991a4f758532e1af","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2014-01-23T02:48:07Z","title_canon_sha256":"5cc6cd29612c480673db1bf56db7177335b6d3bab1c6d24f32d212478f565b44"},"schema_version":"1.0","source":{"id":"1401.6422","kind":"arxiv","version":1}},"canonical_sha256":"0fa75a93274b364bc0108133ea08d2e45b0c623c78f75c97ad487e5130a2824d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0fa75a93274b364bc0108133ea08d2e45b0c623c78f75c97ad487e5130a2824d","first_computed_at":"2026-05-18T03:01:12.058925Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:01:12.058925Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2e0v1FKRLOT4tApP6ctKOPrmUY5n/hc29Wavub2BjubZkF3bR8kmj38HzLdzaLjNUSXHKBof5reQL7ltvixrBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:01:12.059660Z","signed_message":"canonical_sha256_bytes"},"source_id":"1401.6422","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0a5ddbd4c2b5788ae597a92e0bc59b7ded355ebcfd1a8503dfe6dedac948c34e","sha256:d86312f3063984001bb08afcb6140ce22fab25196fe53aa4a170e2501d1baff8"],"state_sha256":"4c03ebbdfc2f04ffc2d36bef43208015593af0eda2001de7173003f922de996e"}
