Previous approaches either match sentences from a single direction or only apply single granular (word-by-word or sentence-by-sentence) matching. In this work, we propose a bilateral multi-perspective matching (BiMPM) model under the \"matching-aggregation\" framework. Given two sentences $P$ and $Q$, our model first encodes them with a BiLSTM encoder. Next, we match the two encoded sentences in two directions $P \\rightarrow Q$ and $P \\leftarrow Q$. In each matching direction, each time step of one sentence is","authors_text":"Radu Florian, Wael Hamza, Zhiguo Wang","cross_cats":["cs.CL"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2017-02-13T15:26:27Z","title":"Bilateral Multi-Perspective Matching for Natural Language Sentences"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.03814","kind":"arxiv","version":3},"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":"sha256:9afabd7a3f1cffc6748ea5190d4d108cd20c4db3dd066a4e4391c5328c143138","target":"record","created_at":"2026-05-18T00:40:17Z","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":"2c78efac83cb2d50214ddda13c7034bc0bc2d5c2b84f46f1f04bca4ad4392afc","cross_cats_sorted":["cs.CL"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2017-02-13T15:26:27Z","title_canon_sha256":"cb8352971b54da085858a2b15b331567c62e609d3a6e982304c999d871dca7c9"},"schema_version":"1.0","source":{"id":"1702.03814","kind":"arxiv","version":3}},"canonical_sha256":"84a897bdb89742998bb4a23ad46b00766a82189e6317e273d9c69f244aadbf22","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"84a897bdb89742998bb4a23ad46b00766a82189e6317e273d9c69f244aadbf22","first_computed_at":"2026-05-18T00:40:17.352642Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:40:17.352642Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7MgoKsPkJu9wvxTASLWZJU11Al42znYI//kAJVHr8YmIBp9JbTdiWnMnYiqNzuxFsrc22/jCa0aLr13cYcEhAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:40:17.353400Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.03814","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9afabd7a3f1cffc6748ea5190d4d108cd20c4db3dd066a4e4391c5328c143138","sha256:578f644c0af840c458967b8f7e51e8bb32ec5599d86387cdb0db5207e48a32b7"],"state_sha256":"c5ad4425a274e6bccbb1dc083e7f43859d3c828899508e32987744cafb8a992e"}
