Human perception of the term \\emph{suggestion} is subjective and this effects the preparation of hand labeled datasets for the task of suggestion mining. Existing work either lacks a formal problem definition and annotation procedure, or provides domain and application specific definitions. Moreover, many previously used manually labeled datasets remain proprietary. We first present an annotation study, and based on our observations propose a formal task definition and a","authors_text":"Maarten de Rijke, Paul Buitelaar, Sapna Negi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-06-06T13:38:57Z","title":"Open Domain Suggestion Mining: Problem Definition and Datasets"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.02179","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":"sha256:9374045e4999936c41830866cf8344ba810edc080ea78b87fbdd24a283821081","target":"record","created_at":"2026-05-18T00:11:56Z","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":"faf3f882975cd91049dd75e7cf6095f2c592d3d8dc53f9020898968690e36933","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-06-06T13:38:57Z","title_canon_sha256":"b2e3919ce85645673d3f09f7065581c3e60b64b3bb70d6a6b370eee1c82ba428"},"schema_version":"1.0","source":{"id":"1806.02179","kind":"arxiv","version":2}},"canonical_sha256":"c0b3a4c3ce6c85af41c1d76af586ee3c1443bf7a4383df8331e3ea7dcb95a030","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c0b3a4c3ce6c85af41c1d76af586ee3c1443bf7a4383df8331e3ea7dcb95a030","first_computed_at":"2026-05-18T00:11:56.689921Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:11:56.689921Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VqPSFQ1PQdtRG4NHY3H6xWL2w+WqaPp5Zfl1jmgM4Z+ulcKlB2DqPL/vEfscsi24NH5lscAvZSOKT8MIoTjABw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:11:56.690634Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.02179","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9374045e4999936c41830866cf8344ba810edc080ea78b87fbdd24a283821081","sha256:5921023bd82629d2550830035008e8e65ef8e17f36850fa01c1d4eaeeba1e545"],"state_sha256":"19604de32f72e08e7350dbe2b820200286ed54fbef542fe30175be067d670397"}
