Although deep learning methods like CNNs, RNNs, and Transformer-based models like BERT have enhanced fake news detection, they primarily focus on content, overlooking social context during news propagation. Graph-based techniques have incorporated this social context but are limited by the need for large labeled datasets. Addressing these challenges, this paper introduces GAMC, an unsupervised fake news detection technique using the ","authors_text":"Chao Gao, Shu Yin, Zhen Wang","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.SI","submitted_at":"2023-12-10T03:34:29Z","title":"GAMC: An Unsupervised Method for Fake News Detection using Graph Autoencoder with Masking"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2312.05739","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:b74294b2b909ccc0ae88ef30e3720889d799ddd7716c6b3735ce4b78b016167a","target":"record","created_at":"2026-07-05T07:22:31Z","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":"9460bfde9db5247898fbec19d79ec40758c5a36e15191f8db9ca0d0e6b5b71f3","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.SI","submitted_at":"2023-12-10T03:34:29Z","title_canon_sha256":"0b7fe4dfecc556ebf719d8d39376419520b2b07d97e7e5ebe2c64081bda17ebb"},"schema_version":"1.0","source":{"id":"2312.05739","kind":"arxiv","version":1}},"canonical_sha256":"d7e3634dd3536d25e9776437730ed77d744cec3dee5ae621b29f804def9858e0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d7e3634dd3536d25e9776437730ed77d744cec3dee5ae621b29f804def9858e0","first_computed_at":"2026-07-05T07:22:31.866796Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:22:31.866796Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YmAkPFoB2jt8NoWYmGMqbKn1bA4agZF3VFqylse8RXiKcezmXQCOYMOQUhRKKjHqpwEmSK3C1SG1ux3rmF98Cg==","signature_status":"signed_v1","signed_at":"2026-07-05T07:22:31.867248Z","signed_message":"canonical_sha256_bytes"},"source_id":"2312.05739","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b74294b2b909ccc0ae88ef30e3720889d799ddd7716c6b3735ce4b78b016167a","sha256:c7a05c81793642fd4531313368eedb1f114fd34af3c86a4a897098f5c6032813"],"state_sha256":"bb607450e019a331d23dfa68cf605716b77c0cf48dba2717f626584acac0468d"}
