On the other hand, it comes up with a new scheme TF-KLD-KNN to learn the discriminative weights of words and phrases specific to paraphrase task, so that a weighted sum of embeddings can represent sentences more effectively. Based on these two innovations we get competitive state-of-the-art performance on paraphrase identification.","authors_text":"Hinrich Sch\\\"utze, Wenpeng Yin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2016-04-02T13:57:02Z","title":"Discriminative Phrase Embedding for Paraphrase Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.00503","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":"sha256:2a4d2fa2bcfd1848455e1643b3ae06ce6d95c677330cd5faf49cc35a63f7ec89","target":"record","created_at":"2026-05-18T01:17:49Z","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":"21c16663dc0a6b7fda8f337fd9e1326e3598621778b3d7040b749ffceb26cbe7","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2016-04-02T13:57:02Z","title_canon_sha256":"4f3a38d5b221e0141ce19ca293d39787d2f30a433b396cad54239cb52308a5a4"},"schema_version":"1.0","source":{"id":"1604.00503","kind":"arxiv","version":1}},"canonical_sha256":"2b2aa661ceff9e010e06896fba2b68061ed005f1d9ad20b4267bb628ab3f4cfe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b2aa661ceff9e010e06896fba2b68061ed005f1d9ad20b4267bb628ab3f4cfe","first_computed_at":"2026-05-18T01:17:49.438252Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:17:49.438252Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bFIV6XWNHSBczhHZkbbv3pJ/TscIdkI3b/pRHbT+KFHG3a+/CdP5pcANN/vg+EZlBb4Lqvvjb/hz6tB6ag++BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:17:49.439092Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.00503","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2a4d2fa2bcfd1848455e1643b3ae06ce6d95c677330cd5faf49cc35a63f7ec89","sha256:0e5267d80f266616c24ed0e476eb7965e5f2a5be645915653efb9d2b03036e4a"],"state_sha256":"ffa6cb6292196ad49e5022d0ed709ce4bd1d1366d602b2d966f188b7900e970c"}
