Patent number: 10565503Abstract: Embodiments are directed to a watched questions threshold filtering system that functions to determine and deliver to a user relevant and significant data changes with respect to a user's goals, as defined by a notification threshold value provided by the user. The user is provided with an option to flag one or more queries for automatic re-querying. Confidence scores are processed on new data (i.e., data ingested after the original question was asked) by utilizing a confidence threshold for indicating if the new data warrants alerting a user.Type: GrantFiled: July 8, 2016Date of Patent: February 18, 2020Assignee: International Business Machines CorporationInventors: Charles E.

Patent number: 10540442Abstract: Mechanisms are provided for evaluating a temporal relevance of a candidate answer to an input natural language question. An input natural language question is received and analyzed to identify a temporal focus of the input natural language question. A corpus of documents is processed based on the input natural language question to generate candidate answers to the input natural language question, where each candidate answer is processed to identify at least one contextual temporal focus associated with the candidate answer. The at least one contextual temporal focus is compared with the temporal focus of the input natural language question and a measure of temporal relevance of the candidate answer based on results of the comparison is generated. A final answer to the input natural language question is output based on the measure of temporal relevance.Type: GrantFiled: July 20, 2016Date of Patent: January 21, 2020Assignee: International Business Machines CorporationInventors: Charles E. Beller, Paul J. Chase, Jr., Richard L. Darden, Edward G. Katz

Publication number: 20180260383Abstract: Large lists of domain-specific terms are classified as a particular kind of linguistic object, e.g., lexical answer type T versus canonical answer E, based on features from a domain-specific corpus which have been found to distinguish between the linguistic objects. The distinguishing features can be identified in the corpus based on sets of the linguistic objects derived from question-and-answer pairs. A classifier can be trained using the distinguishing features, and the classification carried out using that classifier. The distinguishing features can include one or more syntactic features or one or more lexical features. The linguistic objects (the T and E training sets) can be extracted from the question-and-answer pairs automatically via text analysis if manually curated lists are not available. The classified terms can be included in a domain-specific lexicon which facilitates a deep question answering system to yield an answer to a question.Type: ApplicationFiled: June 9, 2017Publication date: September 13, 2018Inventors: Charles E.

Publication number: 20180025280Abstract: Mechanisms are provided for evaluating a temporal relevance of a portion of content to a cognitive operation request. A cognitive operation request is received that comprises a portion of input text and the input text is analyzed, by a temporal relevance evaluation engine, to identify a temporal focus of the input text. A corpus of content is processed based on the input portion of text to generate candidate results each of which are processed to identify at least one contextual temporal focus associated with the candidate result. The at least one contextual temporal focus is compared with the temporal focus of the input text and a measure of temporal relevance of the candidate result is generated based on results of the comparison. The cognitive operation is performed based on the measure of temporal relevance.Type: ApplicationFiled: July 20, 2016Publication date: January 25, 2018Inventors: Charles E. Beller, Paul J.

Publication number: 20170364519Abstract: A mechanism is provided in a computing device configured with instructions executing on a processor of the computing device to implement a question answering system for answer scoring based on a specificity score. The question answering system, executing on the processor of the computing device and configured with a question answering machine learning model, generates a set of candidate answers for a user-generated input question. For each given candidate answer in the set of candidate answers, a specificity scorer of the question answering system determines a specificity value of each term in the given candidate answer based on a position of the term in a taxonomy data structure and determines a specificity score of the given candidate answer based on the specificity value of the terms in the given candidate answer. The question answering system, determines a confidence score for each candidate answer within the set of candidate answers based on its specificity score.Type: ApplicationFiled: June 15, 2016Publication date: December 21, 2017Inventors: Charles E.
