ESP-index is a grammar-based self-index on the notion of edit-sensitive parsing (ESP), an efficient parsing algorithm that guarantees upper bounds of parsing discrepancies between different appearances of the same subtexts in a text. Although ESP-index performs efficient top-down searches of query texts, it has a serious issue on binary searches for finding appearances of variables for a query text, which resulted in slowing down the que","authors_text":"Hiroshi Sakamoto, Yasuo Tabei, Yoshimasa Takabatake","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2014-04-19T17:08:29Z","title":"Improved ESP-index: a practical self-index for highly repetitive texts"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1404.4972","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":"sha256:986e433f77ca625f74de3ee5ed68410b170c76d4660496ed81707dbc514732fd","target":"record","created_at":"2026-05-18T02:53:06Z","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":"91df53a2382e750de2c2b58fefb2c50aa752a1f38c568789018d1e95e9c44752","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2014-04-19T17:08:29Z","title_canon_sha256":"5b6a3a76537cd0266f6a40cec00b66ad893eb649935a49f365720486dd898f40"},"schema_version":"1.0","source":{"id":"1404.4972","kind":"arxiv","version":2}},"canonical_sha256":"9faec109a1c3df6d5e79cdc55263ae61134510b428889ad35fbde45795e405b2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9faec109a1c3df6d5e79cdc55263ae61134510b428889ad35fbde45795e405b2","first_computed_at":"2026-05-18T02:53:06.945855Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:53:06.945855Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+4zioh5oIzh8mqPLto1Y9dcajbQsXYg4lumYewQf0VK7cgIrkmg80qbbDHUOzdYavFL+nDrXem82nuiS/tZPDw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:53:06.946403Z","signed_message":"canonical_sha256_bytes"},"source_id":"1404.4972","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:986e433f77ca625f74de3ee5ed68410b170c76d4660496ed81707dbc514732fd","sha256:7c2487d290254bda2bcdcde6c26a74c5d1f7288addf4d30466db72fa81099dd9"],"state_sha256":"0f2d7b73c216be01b6735c7595a6b7bc7d699ea98c554f2a5677a9a094148372"}
