Previous studies have attempted to detect unseen entities that are not registered in a particular knowledge base as emerging entities and consequently find non-emerging entities since the absence of entities in knowledge bases does not guarantee their emergence. We therefore introduce a novel task of discovering truly emerging entities when they have just been introduced to the public through microblogs and propose an effective method ba","authors_text":"Masashi Toyoda, Naoki Yoshinaga, Satoshi Akasaki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-07-08T11:13:42Z","title":"Early Discovery of Emerging Entities in Microblogs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.03513","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:d2dc0d5eecc3817ccdbc534f6f929605a9929401c0c2e79822de6f1c877040d6","target":"record","created_at":"2026-05-17T23:41:14Z","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":"f397b9c7b7e822186a8965a12dfa34393f041f7435a393754bef83c197921697","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-07-08T11:13:42Z","title_canon_sha256":"26551df59d979708da540898a85274c0482eaa73f96b3fb730758f11617c9f9f"},"schema_version":"1.0","source":{"id":"1907.03513","kind":"arxiv","version":1}},"canonical_sha256":"7fa059e15b70340025c66b4ebc3895d78a6c5f10f2f0f88b128f82c75d0bed70","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7fa059e15b70340025c66b4ebc3895d78a6c5f10f2f0f88b128f82c75d0bed70","first_computed_at":"2026-05-17T23:41:14.420976Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:14.420976Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XXvFZuRFkwX3Vi9SHWuDgw70hrtWfXSUl74/i7QWhxcU24fomIRl62rxX3YuWndLP5gfDKMDxGazjAn4ISv5Cw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:14.421330Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.03513","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d2dc0d5eecc3817ccdbc534f6f929605a9929401c0c2e79822de6f1c877040d6","sha256:a1a050cc01f497d63ea694f5ba256a3cb199c0a98cc7e83d20c0253f1682cce2"],"state_sha256":"73146ac86382df146f553a673804005ef1869331d11d7833fdc8071c2c4993e4"}
