Thus, we propose the use of tree-structured Long Short-Term Memory with an attention mechanism that pays attention to each subtree of the parse tree. Experimental results indicate that our model achieves the state-of-the-art performance in a Japanese sentiment classification task.","authors_text":"Mamoru Komachi, Ryosuke Miyazaki","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2017-04-04T09:08:46Z","title":"Japanese Sentiment Classification using a Tree-Structured Long Short-Term Memory with Attention"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1704.00924","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":"sha256:337c52e2e8b2b9eedc9819c28398e48c59d693d247ff41322b7b8803e59900b3","target":"record","created_at":"2026-05-18T00:04:32Z","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":"e170c053e9ff12b1da86d4c6ac2cec86c400a0552a5f90bbfbe164973f19b6e3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2017-04-04T09:08:46Z","title_canon_sha256":"8cab25892efc2ee3b5606c591817f4264ba7d3bdce30406b1b1e198d837e4d94"},"schema_version":"1.0","source":{"id":"1704.00924","kind":"arxiv","version":2}},"canonical_sha256":"b0de7ce29429dd78cf622ee00fe631c3147f9bb8a27bc58089c95f789528195d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b0de7ce29429dd78cf622ee00fe631c3147f9bb8a27bc58089c95f789528195d","first_computed_at":"2026-05-18T00:04:32.621164Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:04:32.621164Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"o4CAAXw0iP9CRintqWXk3wgnTMeJW1VQZfpkMLZjTUzy5Ai0Zju82495Mk7YjDh8RUjW20oQb/ZgbDlJRs0+CA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:04:32.621797Z","signed_message":"canonical_sha256_bytes"},"source_id":"1704.00924","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:337c52e2e8b2b9eedc9819c28398e48c59d693d247ff41322b7b8803e59900b3","sha256:15ca9609d01a954d13b37d33fb61db9a49449d4203aec2bd5c1941b8442acfaa"],"state_sha256":"fd57db96454145f7d4a26659a39441ef2823f8ff467992c2f513e52f7c6e4a21"}
