This is an extended ver- sion of our workshop paper (Hettinger et al., 2018) including further technical details (Sec- tions 3.2 and 4.3) and changes made to the preprocessing step in the post-evaluation phase (Section 2.1). Due to these changes Classification of Relations using Embeddings (ClaiRE) achieved an improved F1 score of 75.11% for the first subtask and 81.44% for the second.","authors_text":"Albin Zehe, Alexander Dallmann, Andreas Hotho, Lena Hettinger, Thomas Niebler","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-04-16T17:52:36Z","title":"ClaiRE at SemEval-2018 Task 7 - Extended Version"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.05825","kind":"arxiv","version":3},"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:c25925f351b2979394b249ae73e30232aba94192d154aefb3067f242a0a98110","target":"record","created_at":"2026-05-18T00:15:49Z","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":"20da301b8066b010f480cf8e8c1c60cdeeb376f07d95d42b6a3665dbd7ae4d17","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-04-16T17:52:36Z","title_canon_sha256":"ea207527bee70ebc46e31806fa03c5d623cf9c0c842905aad08de8977775e488"},"schema_version":"1.0","source":{"id":"1804.05825","kind":"arxiv","version":3}},"canonical_sha256":"b23594d252f3ae3f0e626dcd04d1cbd4d0627b0b70a572f60234008940b7684c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b23594d252f3ae3f0e626dcd04d1cbd4d0627b0b70a572f60234008940b7684c","first_computed_at":"2026-05-18T00:15:49.565055Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:49.565055Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"saQuugm7hbdI+PFMEzAtpTLs6JP1BU2n+jMDc4C8qZ4MXwZQ210t8RI06XEitfacVzSheebBQ86AZjhzyaEMCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:49.565674Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.05825","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c25925f351b2979394b249ae73e30232aba94192d154aefb3067f242a0a98110","sha256:358a6e262fd66949a9efeb9c4750444981cbc4571978ca244b75e29c9eb96583"],"state_sha256":"6d97a9d2e772d5c19f7aaa100d7272c51da1ff3681ab6985e5b9b32578ad4f8c"}
