  • Patent number: 10642874
    Abstract: A mechanism is provided in a data processing system for using paraphrase metrics for answering questions. The mechanism receives an input question and generating a candidate answer from a corpus of information. The candidate answer has a supporting passage from the corpus of information. The mechanism divides the input question into a first sequence of tokens and divides the supporting passage into a second sequence of tokens. The mechanism identifies a plurality of subsequences of tokens within the second sequence of tokens and applies a paraphrase metric to compare the first sequence of tokens to each of the plurality of subsequences of tokens to generate a plurality of paraphrase metric scores. The mechanism then determines a confidence score for the candidate answer based on a highest paraphrase metric score within the plurality of paraphrase metric scores.

  • Patent number: 10168870
    Abstract: Annotations can be handled by a computer system that receives a query that specifies parameters for extraction of particular annotations from a set of annotations. Annotations include metadata that describes properties of the associated text fragment. A first entity subset, a second entity subset and a relations subset of annotations are extracted from an annotated text corpus. Contextual information relative to the extracted annotations is also extracted from the corpus. A user interface is generated to display frame elements that include the extracted annotations subsets and the extracted contextual information. In response to selections to the frame elements, the system receives input that specifies modifications to the annotations. Based on the input received, the set of annotations is modified in the annotated text corpus.

  • Patent number: 9860308
    Abstract: Collaborative annotation of a document. A GUI is generated by a host computer that displays a document to annotate. The GUI is transmitted by the host computer to a plurality of client computers. Real time communication modes are established by the host computer between the client computers, each including communication channels between all the client computers. The host computer receives annotations entered into the GUIs at the client computers, each annotation identifying a span of words in the document to annotate and including an associated annotation type. The host computer updates the GUI to include for display the received annotations and inter-rater agreement statistics indicating the level of agreement between annotations received from each client computer and annotations received from the other client computers. The updated GUI is then transmitted by the host computer to the plurality of client computers.

  • Patent number: 9805613
    Abstract: A method for providing adaptation to a question answering (QA) system having an associated plurality of trace data and a question-answer set. The method includes submitting a set of questions to the QA system; receiving back from the QA system a set of answers; comparing the set of answers to answers in the question-answer set; and generating the plurality of trace data based on comparison, and an estimate of how much more training data is needed. The generating comprises (a) for each question type, successively sample an increasing number of question-answer pairs from the question-answer set; (b) automatically train the QA system using the sampled question-answer pairs; (c) automatically compute a functional dependence of the QA system performance on the remaining questions relative to the size of the sample; and (d) extrapolate from the functional dependence a number of training question-answer pairs of each question type.

  • Patent number: 9483731
    Abstract: In a method of answering questions and scoring answers, a title and at least one topical field are identified for a document. A field name and field content associated with the topical field is identified, and a title-oriented document is created by combining the title, the field name, and the field content associated with the topical field. For each title-oriented document, a term in the title is matched to previously established categories to produce a title concept identifier. The topical field is synthesized to produce a field concept identifier and a field content concept identifier. A question is received. The question topic term and the question content identifier are used to identify at least one question-matching relation instance. The title concept identifier of each question-matching relation instance is identified as a candidate answer to the question. Each candidate answer and a corresponding answer score is output.
