Previous methods sequentially encode features with a specified order. They first encode the emotion and cause features for clause extraction and then combine them for pair extraction. This lead to an imbalance in inter-task feature interaction where features extracted later have no direct contact with the former. To address this issue, we propose a novel Pair-Based Joint Encoding (PBJE) network, which generates pairs and clauses features simultan","authors_text":"Junlong Liu, Qianli Ma, Xichen Shang","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2022-12-04T15:24:14Z","title":"Pair-Based Joint Encoding with Relational Graph Convolutional Networks for Emotion-Cause Pair Extraction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.01844","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":"sha256:7f071daa2ebf6aec95cb6f76833d72a5ee61ba5ca8cf32fb2a24ac98221daed5","target":"record","created_at":"2026-07-05T05:22:17Z","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":"4d58be53755ce10718cb2e4be64dc451a40f676389a2d8e2fd13fc2539e51c68","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2022-12-04T15:24:14Z","title_canon_sha256":"13494495326489e4c1e013ba597a09b653d148b7b78d6fe47e08838f737eb04f"},"schema_version":"1.0","source":{"id":"2212.01844","kind":"arxiv","version":1}},"canonical_sha256":"72813d1fa3ef7cf5d9b02357e3cd0a2feae7e2d6da311b7c051b930e6dd45591","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"72813d1fa3ef7cf5d9b02357e3cd0a2feae7e2d6da311b7c051b930e6dd45591","first_computed_at":"2026-07-05T05:22:17.356126Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:22:17.356126Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6QZYKe0MBs/GyBlwQ4QNM6ZZcGjvmSYCyOKn44HB8KCvD7zxwzHbrtuBURbQW8BKdjswCldwmX/2GizKw/VGDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:22:17.356512Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.01844","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7f071daa2ebf6aec95cb6f76833d72a5ee61ba5ca8cf32fb2a24ac98221daed5","sha256:c00336e4b406e8aef1273c27baaab441221a05d2f8bb5aef742dba3c0a3fca02"],"state_sha256":"7ec5016233d8bf7b22ecbb4b922a28ccad2f14375fe0abfc0992a70e14610d8e"}
