In most previous applications of universal schema, each textual pattern is represented as a single embedding, preventing generalization to unseen patterns. Recent work employs a neural network to capture patterns' compositional semantics, providing generalization to all possible input text. In response, this paper introduces significant further improvements to the coverage and flexibility of universal sche","authors_text":"Andrew McCallum, Benjamin Roth, David Belanger, Emma Strubell, Patrick Verga","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2015-11-19T21:42:23Z","title":"Multilingual Relation Extraction using Compositional Universal Schema"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.06396","kind":"arxiv","version":2},"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:d33c46e8ee497b7dfc686db4416570652f0b96237686f5593cf2fc9f0fc5e5a4","target":"record","created_at":"2026-05-18T01:19:40Z","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":"e0225f7b2ded07bcd19829e0f85d150336a209e792f6a4986f96bc9e5ec5f31b","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2015-11-19T21:42:23Z","title_canon_sha256":"4d7dd70a93b3e0d20fc3adcda3fa456d7c79cad9786f10aa29e385b6e18b6eab"},"schema_version":"1.0","source":{"id":"1511.06396","kind":"arxiv","version":2}},"canonical_sha256":"303f5e29f123f16cbf1d9e09353381e2d456cf0b58012ebf4dc10581ee1d7b23","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"303f5e29f123f16cbf1d9e09353381e2d456cf0b58012ebf4dc10581ee1d7b23","first_computed_at":"2026-05-18T01:19:40.468507Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:19:40.468507Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+w/wdFjXmuroFkRlrs82lNbawFu50gSCgp9J+NFSifp5FicrRcbBSHg1bVDEmmaG1WFQ6N1zR450c1/Vv5HjAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:19:40.469160Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.06396","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d33c46e8ee497b7dfc686db4416570652f0b96237686f5593cf2fc9f0fc5e5a4","sha256:1651a5f8b9a37b57f695f135a0a8d9096f50a2bda406ebc00f04558a494b1403"],"state_sha256":"1c3e4ad8e43892c59d87c06ee0cd93c5a3fcbb904f0f2e30c57bca21f1d8e2ac"}
