Patent number: 11720611Abstract: Generating textual entailment pair by a natural language processing (NLP) system. The NLP system receives two input texts, such as a question and a candidate answer. The NLP system queries a database and retrieves passages likely to include text that support the candidate answer. The NLP system generates parse trees and performs term matching on the passages and scores them according to the matching. The NLP system detects anchor pairs in the question and in the passage and aligns subgraphs (within the parse trees) of one to the other based on matching. The NLP system identifies aligned terms in the question and the passage that are not in the aligned subgraphs. The NLP system identifies text fragments, for the question and the passage, within the non-aligned segments of their respective parse trees, that connect the aligned term to the aligned portion of the subgraph.Type: GrantFiled: May 20, 2016Date of Patent: August 8, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Branimir K. Boguraev, Jennifer Chu-Carroll, Aditya A. Kalyanpur, David J. McClosky, James W. Murdock, IV, Siddharth A. Patwardhan

Patent number: 10671929Abstract: Mechanisms are provided in a question answering (QA) system comprising a QA system pipeline that analyzes an input question and generates an answer to the input question, for pre-processing the input question. The mechanisms receive an input question and input the input question to a pre-processor flow path having one or more pre-processors. The one or more pre-processors transform the input question into a transformed question by correcting errors in a formulation of the input question that are determined to be detrimental to efficient and accurate processing of the input question by a QA system pipeline of the QA system. The transformed question is then input to the QA system pipeline of the QA system which processes the transformed question to generate and output an answer to the input question.Type: GrantFiled: August 29, 2014Date of Patent: June 2, 2020Assignee: International Business Machines CorporationInventors: Branimir K.
