Recent works, including those considered state-of-the-art, ignore event-nouns or build a single model for solving both Japanese predicate argument structure analysis (PASA) and event-noun argument structure analysis (ENASA). However, because there are interactions between predicates and event-nouns, it is not sufficient to target only predicates. To address this problem, we present a multi-task learning method for PASA and ENASA. Our multi-task models improved the performance of both tasks compared to a single-task ","authors_text":"Hikaru Omori, Mamoru Komachi","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2019-04-03T21:29:14Z","title":"Multi-task Learning for Japanese Predicate Argument Structure Analysis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.02244","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":"sha256:1cf2d58cf4d31e52b926d977ab0d25cf6d33fb094bdae73cff4a5fd5df93eca5","target":"record","created_at":"2026-05-17T23:49:24Z","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":"d0647c39691497afc3f1fae1eabb9236a05d75a30618976f00ac945b3f5e418f","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2019-04-03T21:29:14Z","title_canon_sha256":"7b52e6f85ca5b590f7f21b47cea0ced1ac0ba38c1511a37feb4c4dc82ef53681"},"schema_version":"1.0","source":{"id":"1904.02244","kind":"arxiv","version":1}},"canonical_sha256":"9a801e3ed61ac3ad02e91cf811cfe95623b4129cd4e5fd84d0d7f9c2b3cfa610","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a801e3ed61ac3ad02e91cf811cfe95623b4129cd4e5fd84d0d7f9c2b3cfa610","first_computed_at":"2026-05-17T23:49:24.108047Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:24.108047Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WoZmpSm7KzBcF66vo0tNJbrob8KyL6v+/Su0PBqGGhzybk6wncUg+gLs7lslT+gX5KFiwu2EUcjF1uGK3EmICw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:24.108676Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.02244","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1cf2d58cf4d31e52b926d977ab0d25cf6d33fb094bdae73cff4a5fd5df93eca5","sha256:e2b5a0afee307724328a3d6c1dbd58f1b54c39500f38b6f291429c19d3741faa"],"state_sha256":"233af4ef58d855d1c28e9140c0a485d36473dfa251d65b1ac9682e4d8728e674"}
