Given a set of premises and a\nhypothesis, it is able to prove semantic relations between them. The prover is\nbased on a version of analytic tableau method specially designed for natural\nlogic. The proof procedure operates on logical forms that preserve linguistic\nexpressions to a large extent. %This property makes the logical forms easily\nobtainable from syntactic trees. %, in particular, Combinatory Categorial\nGrammar derivation trees. The nature of proofs is deductive and transparent. On\nthe FraCaS and SICK textual entailment datasets, the prover achieves high\nresults comparable to state-of-the-art.","url_abs":"http://arxiv.org/abs/1708.09417v1","url_pdf":"http://arxiv.org/pdf/1708.09417v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"langpro-natural-language-theorem-prover","repo_url":"https://github.com/kovvalsky/LangPro","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":{"status":"unanswered"}}],"tasks":[{"task_slug":"automated-theorem-proving","task_name":"Automated Theorem Proving"},{"task_slug":"natural-language-inference","task_name":"Natural Language Inference"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1708.09417","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
