However, it is challenging and time-consuming to design the intents for a new domain from scratch, which usually requires a lot of manual effort of domain experts. This paper presents an unsupervised two-stage approach to discover intents and generate meaningful intent labels automatically from a collection of unlabeled utterances in a domain. In the first stage, we aim to generate a set of semantically coherent clusters where the utterances within each cluster convey t","authors_text":"Helen Meng, King Keung Wu, Kun Li, Pengfei Liu, Youzhang Ning","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.CL","submitted_at":"2021-04-25T09:36:23Z","title":"Open Intent Discovery through Unsupervised Semantic Clustering and Dependency Parsing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2104.12114","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:dd7a24bd5e14a9a35a084707d0a0bf7430604812f9d95b07500fbf091280e35d","target":"record","created_at":"2026-07-05T03:40:33Z","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":"387091f26f5448197e0f635292940065c58efac8cd2f729937882ac81094c676","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.CL","submitted_at":"2021-04-25T09:36:23Z","title_canon_sha256":"c86eb9622c892787fc97f8c898629b00ce9ee46262c77be7355faaef346b3672"},"schema_version":"1.0","source":{"id":"2104.12114","kind":"arxiv","version":2}},"canonical_sha256":"9635874ead7074dd550e56be38244b11e62b671db57e174cae60abedfa4509cf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9635874ead7074dd550e56be38244b11e62b671db57e174cae60abedfa4509cf","first_computed_at":"2026-07-05T03:40:33.669201Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:40:33.669201Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LH/IGkm5gYd1NSo/sbJJs4WJ0635ljIA0/0/CuPge3rBg58//lUD3rdNFCAmJo6rs97y8PhkJ/IWWwE1IpSvDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:40:33.669667Z","signed_message":"canonical_sha256_bytes"},"source_id":"2104.12114","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dd7a24bd5e14a9a35a084707d0a0bf7430604812f9d95b07500fbf091280e35d","sha256:48d0bafa6b4893458baf4f4417a879ce1d82da27102c77f5ff972ac6620314e6"],"state_sha256":"3a74f8ecc6a003728a72316fb55bbcfdff3349251d86bc41fdb5f1d9725e69e3"}
