There have been many studies that learn sequential or structural information for code representation. But sequence-based models and non-sequence-models both have their limitations. Researchers attempt to incorporate structural information to sequence-based models, but they only mine part of token-level hierarchical structure information. In this paper, we analyze how the complete hierarchical structure influences the tokens in code sequences and abstract this influence as a property of code tokens called h","authors_text":"Ge Li, Kechi Zhang, Zhi Jin, Zhuo Li","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2023-03-14T12:01:39Z","title":"Implant Global and Local Hierarchy Information to Sequence based Code Representation Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.07826","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:ead65c1f039646e99176802c845ac824dff7136876fc62923299f7f9bd9be823","target":"record","created_at":"2026-07-05T05:51:11Z","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":"47f831ba8e5529f1a735a51b0a1488fe35a9a8f2208ce76dfbadc6d15f72aeee","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2023-03-14T12:01:39Z","title_canon_sha256":"d2b30c94a313a1b1e5f89620068d94339b4824e8b0863a37ce4aca9da3b9ef80"},"schema_version":"1.0","source":{"id":"2303.07826","kind":"arxiv","version":1}},"canonical_sha256":"c5645f4d7beef681e0065edc92211e7d1c298ca3acf20d70ed44be865b43cbcb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c5645f4d7beef681e0065edc92211e7d1c298ca3acf20d70ed44be865b43cbcb","first_computed_at":"2026-07-05T05:51:11.999768Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:51:11.999768Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qwhn6sD0q0gCPEEEgj0i+KLOvZ+kLRmNIoz08HnNfiRDdTOrODpded8O8Ug34JF1o4FPFTKGlXI4XagvY1SWCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:51:12.000187Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.07826","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ead65c1f039646e99176802c845ac824dff7136876fc62923299f7f9bd9be823","sha256:7f75fcf7da82f3aeaa69c3a57c3147a9d0636e07657b6f76883358469682eee4"],"state_sha256":"42de328ab1e260f7b1a7fdebe0d379ea376382a355c557ad59544e0bfbbf915b"}
