Such interpretation is known variously as the symbol grounding problem, grounded semantics and grounded language acquisition. This problem is challenging because people employ diverse vocabulary and grammar, and because robots have substantial uncertainty about the nature and contents of their surroundings, making it difficult to associate the constitutive language elements (principally noun phrases and spatial relations) of the co","authors_text":"Abraham Bachrach, Albert Huang, Ashis Banerjee, Deb Roy, Emma Brunskill, Matthew Walter, Nicholas Roy, Sachi Hemachandra, Seth Teller, Stefanie Tellex, Thomas Kollar","cross_cats":["cs.RO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2017-11-29T21:20:51Z","title":"Generalized Grounding Graphs: A Probabilistic Framework for Understanding Grounded Commands"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.01097","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":"sha256:6364043a1a21d50059064f8a4dc2b42f31e4ff42c2d037facb9b800cfe952b0c","target":"record","created_at":"2026-05-18T00:28:59Z","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":"65324af68ab9de85ab8a8cd572c225fbab77938e16f6415312237d9f3f73b4e2","cross_cats_sorted":["cs.RO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2017-11-29T21:20:51Z","title_canon_sha256":"d05c12d05c166a43c17cbf998cb1de88e7b6f831c3ce7c32ac770d1f23a5418f"},"schema_version":"1.0","source":{"id":"1712.01097","kind":"arxiv","version":1}},"canonical_sha256":"117f2ce1dd1ebe5e21d1b9ec2247b7483a68a43a975cdf1874b6f2f56de0cf10","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"117f2ce1dd1ebe5e21d1b9ec2247b7483a68a43a975cdf1874b6f2f56de0cf10","first_computed_at":"2026-05-18T00:28:59.530560Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:28:59.530560Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1+5oG2pMb8wPtQECIqnUgYsr4ZTkpab2QNHutcuf398/g+6xZ3vtFUnt8qhlqUH+a3O6CoSYxVW/+rijjmUeCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:28:59.531087Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.01097","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6364043a1a21d50059064f8a4dc2b42f31e4ff42c2d037facb9b800cfe952b0c","sha256:518457bb0fb3732e99b48df5b98a60349a4901262af6fd23f632bb84ffb94ce2"],"state_sha256":"7edc72179af830866e481a9e175f6ac19e065db5cde42ff962a98e7569511999"}
