One of the major challenges in an online recruitment scenario is to provide good matches between job posts and candidates using a recommender system on the scale. In this paper, we discussed the techniques for applying an embedding-based recommender system for the large scale of job to candidates matching. To learn the comprehensive and effective embedding for job posts and candidates, we have constructed a fused-embedding via different levels of representation learning from raw text, sem","authors_text":"Bopeng Zhang, Jingya Wang, Jing Zhao, Madhav Sigdel, Mengshu Liu, Mohammed Korayem, Phuong Hoang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IR","submitted_at":"2021-07-01T05:18:32Z","title":"Embedding-based Recommender System for Job to Candidate Matching on Scale"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2107.00221","kind":"arxiv","version":1},"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":"sha256:9d348ef0a6210fb4be664d2857657a2d52214203cd279d1da011ad92e303ec65","target":"record","created_at":"2026-07-05T02:54:22Z","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":"139bd7f98f4042a743db4d73bf54f0f9ccde640ec37099d0801e48f805c74067","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IR","submitted_at":"2021-07-01T05:18:32Z","title_canon_sha256":"f78726972741d44806f50bc04bf6d813706ad434a26c903925756087393c9f4e"},"schema_version":"1.0","source":{"id":"2107.00221","kind":"arxiv","version":1}},"canonical_sha256":"39cc0a4ee9d0bdd4daafc4f45003984419d91b38669929612840ba95b55d273b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"39cc0a4ee9d0bdd4daafc4f45003984419d91b38669929612840ba95b55d273b","first_computed_at":"2026-07-05T02:54:22.227800Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:54:22.227800Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0yddkI+pdXGBCMf/uaYHuEyd57KR9m/k8dA/6wCeEqa4Nnr/p6vihI8LLNc7M7l8e0pPFlWP14LtwqGo0MiSAA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:54:22.228201Z","signed_message":"canonical_sha256_bytes"},"source_id":"2107.00221","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9d348ef0a6210fb4be664d2857657a2d52214203cd279d1da011ad92e303ec65","sha256:2f9fdc730a5f884d5bee4bdb08e69457854951a3572133e851d866ecf08545ed"],"state_sha256":"e350c53ab1576334e41351898ff25a938c37fb942e96f853c08e7f38b0010141"}
