The network operates at the paragraph level and integrates convolutional and recurrent neural networks, as well as a similarity matrix as part of the overall architecture. The experimental evaluation on the Fake News Challenge dataset shows state-of-the-art performance.","authors_text":"Alessandro Moschitti, James Glass, Lluis Marquez, Mitra Mohtarami, Preslav Nakov, Ramy Baly","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-04-20T12:48:10Z","title":"Automatic Stance Detection Using End-to-End Memory Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.07581","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:a93b4c4d4052dae003ef92afdc92abb25b755f40614045b5abd863fc6ebd3254","target":"record","created_at":"2026-05-18T00:17:58Z","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":"ebe970eb299928a7dfb898a504708160bf84a34d4283379eb188b7c73d530090","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-04-20T12:48:10Z","title_canon_sha256":"9b72d38ea56ee0b113abd8dfa8e435b4cdd5f4cd4e1f499135218d1f5922a1a6"},"schema_version":"1.0","source":{"id":"1804.07581","kind":"arxiv","version":1}},"canonical_sha256":"5a6ad8556e25432d481043ac877bb12b252908e54708808caa261891a2c49359","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a6ad8556e25432d481043ac877bb12b252908e54708808caa261891a2c49359","first_computed_at":"2026-05-18T00:17:58.404226Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:58.404226Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SS26K88zzGyz80mSon+CPcOay5+2iir8cszALrbbkaDDII2kkDFhyMMH16mFfFb6Wef64WcNkJX2NQwAKhLeAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:58.404746Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.07581","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a93b4c4d4052dae003ef92afdc92abb25b755f40614045b5abd863fc6ebd3254","sha256:d02a2b9d45026cd534b19a5be17d081720a7333f99bdff9a83aea455c53333fb"],"state_sha256":"82c241cf1a3f9bb36b98e76467bd79c224ac9a7a45d5fc9da208f1290c01a37a"}
