In this paper, we extend a pitch accent detector that involves a convolutional neural network to include word embeddings, which are state-of-the-art vector representations of words. We examine the effect these features have on within-corpus and cross-corpus experiments on three English datasets. The results show that while word embeddings can improve the performance in corpus-dependent experiments, they also have the potential to make generaliz","authors_text":"Antje Schweitzer, Ngoc Thang Vu, Sabrina Stehwien","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-05-14T15:40:31Z","title":"Effects of Word Embeddings on Neural Network-based Pitch Accent Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.05237","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":"sha256:43aa2e0468ae47f30256234a0297cb5df0323a68aef660a0d428cc66e9110126","target":"record","created_at":"2026-05-18T00:13:57Z","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":"230288a3fb0de7991d05025c3b70a89bec4a0d104412ebbf1add417dedc3289d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-05-14T15:40:31Z","title_canon_sha256":"07e75a80049753c2e94de1c162c0e1ca56bc9c4ac431c5f41f7014b4d8b40c94"},"schema_version":"1.0","source":{"id":"1805.05237","kind":"arxiv","version":2}},"canonical_sha256":"8c1397efc0a67ae0f6eb35b3c176cab562eecb73bc307160ef3cd6129f4f1100","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8c1397efc0a67ae0f6eb35b3c176cab562eecb73bc307160ef3cd6129f4f1100","first_computed_at":"2026-05-18T00:13:57.506277Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:13:57.506277Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ff6w/+lfOCgWmPV8+S+7tO34LUcMGuL50AgoShaf1IUuRVZ2AqQK/7XCtY8nSee+DSIPyCx7hTyNo6ums4oyBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:13:57.506805Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.05237","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:43aa2e0468ae47f30256234a0297cb5df0323a68aef660a0d428cc66e9110126","sha256:a697f6f0dd78844e0f915212e63273c64b16e4c87f108c2e2732ba3ab5e777a8"],"state_sha256":"8d1693c382e9d490b725e5285203357d1925581709fd961d1cf7b4dd89f72ed9"}
