Patent number: 8560300Abstract: The disclosed system and method apply stores of factual information to correct errors in digital text, for example, generated from OCR, speech and/or handwriting recognition devices, and other automatic recognition devices. A text produced by OCR, speech recognition, handwriting recognition, and others may be processed to extract discussed facts. Databases of facts are searched based on information in the text. After comparing facts asserted in the text with the factual data from the databases, suggested corrections of the text are produced.Type: GrantFiled: September 9, 2009Date of Patent: October 15, 2013Assignee: International Business Machines CorporationInventors: David A.

Publication number: 20130018876Abstract: A method, system and computer program product for generating answers to questions. In one embodiment, the method comprises receiving a query, conducting a search through one or more data sources to identify candidate answers to the query, and providing each of the candidate answers with a preliminary score. The method further comprises filtering out any of the candidate answers with a preliminary score that does not satisfy a defined condition. The candidate answers having preliminary scores that satisfy this condition form a subset of the candidate answers. Each of the candidate answers in this subset is processed to produce further scores. A ranking function is applied to these further scores to determine a ranking for each of the candidate answers in the subset; and after this ranking function is applied, one or more of the candidate answers are selected as one or more final answers to the query.Type: ApplicationFiled: September 13, 2012Publication date: January 17, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jennifer Chu-Carroll, David A. Ferrucci, David C. Gondek, Adam P. Lally, James W. Murdock, IV

Publication number: 20130018652Abstract: Diffusing evidence among candidate answers during question answering may identify a relationship between a first candidate answer and a second candidate answer, wherein the candidate answers are generated by a question-answering computer process, the candidate answers have associated supporting evidence, and the candidate answers have associated confidence scores. All or some of the evidence may be transferred from the first candidate answer to the second candidate answer based on the identified relationship. A new confidence score may be computed for the second candidate answer based on the transferred evidence.Type: ApplicationFiled: September 14, 2012Publication date: January 17, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David A.

Publication number: 20130013547Abstract: Evidence profiling, in one aspect, may receive a candidate answer and supporting pieces of evidence. An evidence profile may be generated, the evidence profile communicating a degree to which the evidence supports the candidate answer as being correct. The evidence profile may provide dimensions of evidence, and each dimension may support or refute the candidate answer as being correct.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric W. Brown, Jennifer Chu-Carroll, James J. Fan, David A. Ferrucci, David C. Gondek, Anthony T. Levas, James W. Murdock, IV

Publication number: 20120330882Abstract: A system and a computer program product for verifying a statement are provided. The system is configured to receive a statement. The system is configured to decompose the received statement into one or more sets of question and answer pairs. The system is configured to determine a confidence value of each answer in the one or more question and answer pair sets. The system is configured to combine the determined confidence values. The combined confidence values represent a probability that the received statement is evaluated as true.Type: ApplicationFiled: August 31, 2012Publication date: December 27, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David A.

Patent number: 8332394Abstract: A system, method and computer program product for conducting questions and answers with deferred type evaluation based on any corpus of data. The method includes processing a query including waiting until a “Type” is determined AND a candidate answer is provided; the Type is not required as part of a predetermined ontology but is a lexical/grammatical item. Then, a search is conducted for evidence that the candidate answer has the required LAT (e.g., as determined by a matching function leveraging a parser, a semantic interpreter and/or a pattern matcher). Alternately, the LAT may be matched to a known Ontological Type and then a candidate answer searched in an knowledge-base or database determined by that type. Then, all the evidence from all the different ways to determine that the candidate answer has the expected lexical answer type (LAT) is combined and one or more answers provided.Type: GrantFiled: May 23, 2008Date of Patent: December 11, 2012Assignee: International Business Machines CorporationInventors: James Fan, David Ferrucci, David C. Gondek, Wlodek W. Zadrozny

Patent number: 8200656Abstract: A method, system and computer program product are disclosed for searching for information using a knowledge base. In one embodiment, the method comprises receiving a query; formulizing the query, including dividing the query into a plurality of parts; for each of the parts, identifying a source, using the knowledge, that addresses that part; and combining the sources to answer the query. In one embodiment, the query includes text; the text is separated into a plurality of segments; and, for each of the segments, at least one source is identified addressing the segment. In an embodiment, a logical proof is formulated having a conclusion that is an answer to the query, and a sequence of statements that establish said conclusion; and a proof of this conclusion is generated by identifying two or more documents that assert the sequence of statements.Type: GrantFiled: November 17, 2009Date of Patent: June 12, 2012Assignee: International Business Machines CorporationInventors: Eric W. Brown, Jennifer Chu-Carroll, James J. Fan, David A. Ferrucci, David C. Gondek, Anthony T. Levas, James William Murdock, IV

Publication number: 20110125734Abstract: A system, method and/or computer program product for automatically generating questions and answers based on any corpus of data. The computer system, given a collection of textual documents, automatically generates collections of questions about the documents together with answers to those questions. In particular, such a process can be applied to the so called ‘open’ domain, where the type of the corpus is not given in advance, and neither is the ontology of the corpus. The system improves the exploring of large bodies of textual information. Applications implementing the system and method include new types of tutoring systems, educational question-answering games, national security and business analysis systems, etc.Type: ApplicationFiled: March 15, 2010Publication date: May 26, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Pablo A.
