Patent number: 11550794Abstract: A candidate document is received, for example, by a document filter. A determination is made based on the content of the candidate document, whether the candidate document is relevant to a document corpus. A determination is made based on the content of the candidate document, whether the candidate document is novel with respect to the document corpus. In response to determining that the candidate document is relevant to the document corpus and novel with respect to the document corpus, the candidate document is added to the document corpus to make at least a portion of the content of the candidate document available for a response to a search query.Type: GrantFiled: June 26, 2019Date of Patent: January 10, 2023Assignee: International Business Machines CorporationInventors: Charles Evan Beller, William G Dubyak, Palani Sakthi, Kristen Maria Summers

Patent number: 11501006Abstract: Natural language processing is enhanced by linguistically extracting intelligence about a user. A history of user queries is analyzed by a natural language classifier to determine various user intents, and these intents are combined to form a user intent profile. The profile includes elements of sentiment, emotion and tone. The profile can be used in various ways including restricting access to documents in a collection, or refining a cognitive analysis of a query. For access restriction, a determination is made that the user intent is inconsistent with a document, and the user is denied access to the document. This determination involves a user intent score which is compared to a score of the document. For cognitive analysis, searching of reference documents is filtered by excluding documents based on the user intent. The searching includes a comparison of meta-data tags of the documents to the user intent.Type: GrantFiled: March 5, 2018Date of Patent: November 15, 2022Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: William G. Dubyak, Vijai Gandikota, Palani Sakthi

Patent number: 11379706Abstract: Embodiments are directed to interaction with an open-domain question and answer system by recognizing questions that are highly broad or abstract, and generating and processing a batch of questions expressing alternate, concrete instances of the more general, abstract question. Responses to all of the questions in the batch are considered as candidates, and the strongest general answers are returned. A weighted, ranked answer set, based on weighting individual concrete questions and scaling the answers proportional to the weight of the questions, is provided to the user. The approach, according to embodiments herein, addresses the need for responses to broad questions in which a response to any of a set of more concrete question instances may serve to answer the question.Type: GrantFiled: April 13, 2018Date of Patent: July 5, 2022Assignee: International Business Machines CorporationInventors: Charles E. Beller, William G. Dubyak, Palani Sakthi, Kristen M. Summers

Patent number: 11227113Abstract: Batch interaction with a computerized question answering system can produce an answer that more closely relates to a user's information need. A batch of questions can be generated interactively, and provides a context for a first question received from a user. The batch of questions includes or more additional questions which have terms with a nonsynonymous semantic relation to a first term in the first question. A question answering system can process the batch of questions to determine candidate answers. An answer to the first question can be determined based, at least in part, on a combined ranking of the candidate answers.Type: GrantFiled: January 20, 2016Date of Patent: January 18, 2022Assignee: International Business Machines CorporationInventors: Charles Evan Beller, William G Dubyak, Palani Sakthi, Kristen Maria Summers

Patent number: 11170181Abstract: Dynamic semantic processing of text in a word processing application with engagement of question-answering system. A user provides a text stream to a computer system via an input source. The input text stream includes a first natural language statement. The system determines that the first natural language statement includes a fact-based component expressed in natural language form. The system identifies an initial span and an alternative span of the first natural language component, based on the determining. The system engages a question-answering (QA) system by providing the initial span and the alternative span of the first natural language component to the QA system, and by receiving, in response to the providing, a set of natural language results from the QA system. The system evaluates the initial span and the alternative span of the first natural language component based on the received natural language results.Type: GrantFiled: June 27, 2019Date of Patent: November 9, 2021Assignee: International Business Machines CorporationInventors: Charles E.

Patent number: 10621177Abstract: Embodiments are directed to an entity extraction and filtering system that enables a close search of documents to build filters necessary for near real-time monitoring of streaming sources of information. According to an embodiment, the entity extraction and filtering system operates based on the following parameters. First, a detection of an entity of interest warrants flagging an arriving article for analyst attention. Nothing more than a match may be required. The list of entities may be derived by an entity extractor from a corpus of data. Secondly, automatic updates may be utilized, so that exports are automatically updated to the filters. Thirdly, information flowing past the filters may update a static corpus whether or not they are flagged for an analyst or user. This allows for new relationships to be detected and extracted, and the filters subsequently updated.Type: GrantFiled: March 23, 2017Date of Patent: April 14, 2020Assignee: International Business Machines CorporationInventors: Charles E. Beller, William G. Dubyak, Joshua G. Hong, Brian L. Keith, Palani Sakthi, Kristen M. Summers
