Previous works usually take long documents as non-structured flat texts or only consider the local structure in long documents. However, these methods usually ignore the global structure of the long document, which is essential for long-range understanding. To tackle this problem, we propose Compressive Graph Selector Network (CGSN) to capture the global structure in a compressive and iterative manner. The proposed model mainly focuses on the evidence selection phase of long document","authors_text":"Heyan Huang, Wei Wei, Xian-Ling Mao, Yuxiang Nie","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2022-10-11T14:55:12Z","title":"Capturing Global Structural Information in Long Document Question Answering with Compressive Graph Selector Network"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2210.05499","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":"sha256:34a94dc2b54ec6025e2f75559cb989610861174ed3b820c6428a0ef1489d40ee","target":"record","created_at":"2026-07-05T05:08:05Z","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":"6253cb38cf174ac6e3bfde4e73b2f312a233ecb9e20b02d4b74a093ff7f9ee0f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2022-10-11T14:55:12Z","title_canon_sha256":"61b57088ceeeb40be4488741c745b5ba2f4a9ba94e302816ead8954c8b7f2c69"},"schema_version":"1.0","source":{"id":"2210.05499","kind":"arxiv","version":2}},"canonical_sha256":"bb4f32ac8b3be891109a9bda0e21d5b46553598af8d80892f4d7faf1df50b481","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bb4f32ac8b3be891109a9bda0e21d5b46553598af8d80892f4d7faf1df50b481","first_computed_at":"2026-07-05T05:08:05.107634Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:08:05.107634Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6kiVheg6A8iK4AYi0tk5Ggm1LouD7IesbvLe3SupPUiUat7y7/3NaixaPo6vx68+gBh21zDc7vL8hgMYwyLLBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:08:05.108023Z","signed_message":"canonical_sha256_bytes"},"source_id":"2210.05499","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:34a94dc2b54ec6025e2f75559cb989610861174ed3b820c6428a0ef1489d40ee","sha256:4789712ea02bdb14e4618cc43998c874e6141f1fc85e898a7f967f6723fd95f9"],"state_sha256":"a47f7f9e88d9a7dc36d9cc7112c4230b33d5e8fdddb4a7319de9aa79cd8c9f98"}
