It integrates the recommender system and the dialog generation system. The dialog system can enhance the performance of the recommendation system by introducing knowledge-grounded information about users' preferences, and the recommender system can improve that of the dialog generation system by providing recommendation-aware vocabulary bias. Experimental results demonstrate that our proposed model has significant advantages over the baselines in both the evaluation o","authors_text":"Hongxia Yang, Jie Tang, Junyang Lin, Ming Ding, Qibin Chen, Yichang Zhang, Yukuo Cen","cross_cats":["cs.IR","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-08-15T01:49:19Z","title":"Towards Knowledge-Based Recommender Dialog System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.05391","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:c7e5b3d7be9f5f866ba897d495552306a5c112b1639b2e06814ed5eac459f96f","target":"record","created_at":"2026-07-05T00:01:03Z","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":"aaa0f1edea42753f536ceaa56f56a9173102a1c8a758b1d34e0a74e3c13a7c0c","cross_cats_sorted":["cs.IR","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2019-08-15T01:49:19Z","title_canon_sha256":"4dd8369eb3d5e543c8efeb76b94fb66b4708e56f7be54b3c825278c23da74e49"},"schema_version":"1.0","source":{"id":"1908.05391","kind":"arxiv","version":2}},"canonical_sha256":"4cfe89b8bc30d68262fb42ef80158e9433d3d645a666527e30366c960e52e8e2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4cfe89b8bc30d68262fb42ef80158e9433d3d645a666527e30366c960e52e8e2","first_computed_at":"2026-07-05T00:01:03.359863Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:01:03.359863Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6KDXhxWgSrwUDJG80OMAm7r4cMqioTXdF6130mDKpgzYLDC7uSH+zJf/wGUR8s/lw02W4zuO3ffzK++ybfjMCw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:01:03.360270Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.05391","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c7e5b3d7be9f5f866ba897d495552306a5c112b1639b2e06814ed5eac459f96f","sha256:f97ab02ffa1646aad6f69ac14dece4d1ff6fcb441e76120c7be2a8a13c26a961"],"state_sha256":"fa7840e49c4dc69534dd85674b99aaf0ee821c33e9c9e703868b6ccd5a3667bf"}
