This paper presents a span-level hallucination detection framework for the SemEval-2025 Shared Task, focusing on English and Arabic texts. Our approach integrates Semantic Role Labeling (SRL) to decompose the answer into atomic roles, which are then compared with a retrieved reference context obtained via question-based LLM prompting. Using a DeBERTa-based textual entailment model, we evaluate each role semantic alignment with the retrieved context. The entailment scores are further refined ","authors_text":"Mervet Abu-Elkheir, Passant Elchafei","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2025-04-25T18:35:25Z","title":"Span-Level Hallucination Detection for LLM-Generated Answers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.18639","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":"sha256:16a3eb665f81436dd34c9ab8d24dcbf5947caa0c579fbcab9f4bd69b4c3d7cd3","target":"record","created_at":"2026-07-05T10:54:18Z","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":"19f9fc6adb19332597f02e14dae114e0f074359c079f9b0ac9aec25159b53fe7","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2025-04-25T18:35:25Z","title_canon_sha256":"45b91573c859152e14d2cc0ce5126dabeaefd0b34ec426ee516315b3323485a5"},"schema_version":"1.0","source":{"id":"2504.18639","kind":"arxiv","version":1}},"canonical_sha256":"7c97f347d26907017b73ef5b2f07a3532777b56bd0b7a0dc3ab7e2b053306679","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7c97f347d26907017b73ef5b2f07a3532777b56bd0b7a0dc3ab7e2b053306679","first_computed_at":"2026-07-05T10:54:18.246538Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:54:18.246538Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bxWkR/uIh429qHkzAdjW0sdA+r44Py8QmD8GpjstUXoV1rFKNaCPDPnf8RbdNIeo6H5WwUHWRwXlMEpLgWPTDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:54:18.247058Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.18639","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:16a3eb665f81436dd34c9ab8d24dcbf5947caa0c579fbcab9f4bd69b4c3d7cd3","sha256:e24e170bd681d59f75078ae9c2ee04d771fb844a7604c61365aa48167e9e4336"],"state_sha256":"96bda2ce2535fb554a66919a09e8e1f1cf507eba020ae8dbabbefaaf7f376ccb"}
