  • Publication number: 20150347467
    Abstract: 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.

  • Patent number: 9165252
    Abstract: A computerized device for enhancing the accuracy of a question-answer system is disclosed. The computerized device comprises a question-answer system comprising software for performing a plurality of question answering processes. A receiver receives a question into the question-answer system. A processor that generates a plurality of candidate answers to the question is connected to the question-answer system. The processor determines a confidence score for each of the plurality of candidate answers. The processor evaluates sources of evidence used to generate the plurality of candidate answers. The processor identifies missing information from a corpus of data. The missing information comprises any information that improves a confidence score for a candidate answer. The processor generates at least one follow-on inquiry based on the missing information. A network interface outputs the at least one follow-on inquiry to external sources separate from the question-answer system.

  • Patent number: 9047567
    Abstract: 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.

  • Patent number: 8943051
    Abstract: A system, method and computer program product for automatically estimating the confidence of a detected LAT to provide a more accurate overall score for an obtained candidate answer. A confidence “score” or value of each detected LAT is obtained, and the system and method performs combining the confidence score with a degree of match between a LAT and an AnswerType of the candidate answer to provide improved overall score for the candidate answer.

  • Publication number: 20150006537
    Abstract: 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.

  • Patent number: 8892550
    Abstract: 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.

  • Publication number: 20140258286
    Abstract: 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.
