The implementation of these functions has implications for the choices at the heart of algorithmic recommender systems. - A state of the art, which deals with the main techniques used in automated recommendation system: the two most commonly used algorithmic methods, the K-Nearest-Neighbor methods (KNN) and the fast factorizat","authors_text":"Frank Meyer","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2012-03-20T16:14:42Z","title":"Recommender systems in industrial contexts"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.4487","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":"sha256:317be2ffd65265599cb835bffc5af12b0caa5f63c5ac023b9e937048797d61d7","target":"record","created_at":"2026-05-18T03:55:46Z","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":"a21531350421a97ee520a3738e64d362f2f31a823551b00421bc60466dd2ad98","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2012-03-20T16:14:42Z","title_canon_sha256":"1c844cb60cd4e0831058358e536bdb9ff967b567edc11530677d697c8e7fb60b"},"schema_version":"1.0","source":{"id":"1203.4487","kind":"arxiv","version":2}},"canonical_sha256":"13d574c652443e57a132efb7f980c4fa50c06519d647c7bcbaef681070e5f4f0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"13d574c652443e57a132efb7f980c4fa50c06519d647c7bcbaef681070e5f4f0","first_computed_at":"2026-05-18T03:55:46.368854Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:55:46.368854Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1q3L1Ahr2Go9Kag2+aIk7IoyOUYjlEPGkS7AlNpuwzMvGksnTtuovJymPiqt5s9YJlT9Nop6AO71BUdf733gDw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:55:46.369370Z","signed_message":"canonical_sha256_bytes"},"source_id":"1203.4487","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:317be2ffd65265599cb835bffc5af12b0caa5f63c5ac023b9e937048797d61d7","sha256:4c69a11d6e64af8dd8a08df5727fa2f3607c5a111c70eb651b1980f0fa143c09"],"state_sha256":"4bac363238900155d9051c36dbaa16c58bbc88b00ba07ee16714b33fa70848e8"}
