Publication number: 20150347467Abstract: A model of a domain is received, wherein the model has a plurality of elements. A corpus of select documents covering the plurality of elements of the model is also received. A plurality of select topics is generated from the corpus of select documents. Topics of an additional document are compared to the plurality of select topics to calculate a distance between the topics of the additional document and the plurality of select topics. Upon the distance meeting a threshold value, a new corpus is generated to include the additional document. The new document is annotated with the plurality of elements of the model.Type: ApplicationFiled: May 27, 2014Publication date: December 3, 2015Applicant: International Business Machines CorporationInventors: Sara H.

Patent number: 9047567Abstract: A method of enhancing the accuracy of a question-answer system. Missing information from a corpus of data is identified. The missing information is any information that improves a confidence for a candidate answer to a question. A follow-on inquiry is generated. The follow-on inquiry prompts for the missing information to be provided. The follow-on inquiry is output to an external source. A response to the follow-on inquiry is received from the external source. The response is added to the corpus of data.Type: GrantFiled: July 12, 2012Date of Patent: June 2, 2015Assignee: International Business Machines CorporationInventors: Michael A.

Publication number: 20150006537Abstract: An approach is provided in which a question thread management system accumulates a set of questions from a first user into a question thread and classifies the question thread based upon a user profile of the first user. The question thread management system receives a query request from a second user and compares request attributes included in the second user's query request with profile attributes included in first user's user profile. In turn, the question thread management system provides the question thread from the first user to the second user.Type: ApplicationFiled: June 27, 2013Publication date: January 1, 2015Inventors: Jana H. Jenkins, David C. Steinmetz, Wlodek W. Zadrozny

Patent number: 8892550Abstract: System, method and computer program product for 1) preparing queries for retrieving related content based on existing data content. For instance, titles of existing documents or entities extracted from documents can be used as queries. 2) Retrieving content from other repositories of unstructured, semi-structured, or structured data. For instance, web pages can be retrieved using existing search engines. 3) Extracting smaller units of text from the retrieved content. For instance, web pages can be split into coherent paragraphs of text. 4) Judging the quality of the smaller units of text and their relatedness to existing data. For instance, paragraphs can be scored using a statistical model based on lexico-syntactic features and topic models. 5) Synthesizing new sources from high-quality related text. For instance, paragraphs that score above a threshold can be concatenated into a new document.Type: GrantFiled: September 24, 2010Date of Patent: November 18, 2014Assignees: International Business Machines CorporationInventors: Jennifer Chu-Carroll, James J.

Publication number: 20140258286Abstract: System and method for providing answers to questions based on any corpus of data implements a method that generates a number of candidate passages from the corpus that answer an input query, and finds the correct resulting answer by collecting supporting evidence from the multiple passages. By analyzing all retrieved passages and that passage's metadata in parallel, an output plurality of data structures is generated including candidate answers based upon the analyzing. Then, supporting passage retrieval operations are performed upon the set of candidate answers, and for each candidate answer, the data corpus is traversed to find those passages having candidate answer in addition to query terms. All candidate answers are automatically scored by a plurality of scoring modules, each producing a module score. The modules scores are processed to determine one or more query answers; and, a query response is generated based on the one or more query answers.Type: ApplicationFiled: May 21, 2014Publication date: September 11, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric W.
