A mechanism is provided in a data processing system for exploring knowledge. The mechanism receives a set of known facts. The mechanism traverses paths in an ontology for a domain of knowledge from known facts in the set of known facts to one or more hypotheses. The ontology includes a plurality of entity types and a plurality of relationships between the entity types. The mechanism presents one or more hypotheses to a user.

Leveraging an external ontology for graph expansion in inference systems

According to an aspect, a processing system of a question answering computer system determines a first set of relations between one or more pairs of terms in a question. The processing system also determines a second set of relations between one or more pairs of terms in a candidate passage including a candidate answer to the question. The processing system matches the first set of relations to the second set of relations. A plurality of scores is determined by the processing system based on the matching. The processing system aggregates the scores to produce an answer score indicative of a level of support that the candidate answer correctly answers the question.

Evaluating passages in a question answering computer system

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.

Utilizing failures in question and answer system responses to enhance the accuracy of question and answer systems

Systems and methods display at least one subject, and display a location for at least one user to enter at least one problem related to the subject. The problem comprises unknown items to which the user would like more information. In response to the problem, such systems and methods automatically generate evidence topics related to the problem, and automatically generate questions related to the problem and the evidence topics. Further, such systems and methods can receive additional questions from the user. In response to the questions, such systems and methods automatically generate answers to the questions by referring to sources, automatically calculate confidence measures of each of the answers, and then display the questions, the answers, and the confidence measures. When the user identifies one of the answers as a selected answer, such systems and methods display details of the sources and the factors used to generate the selected answer.

User interface for an evidence-based, hypothesis-generating decision support system

A method of validating that a user is human. A user question is generated using a computerized device. The user question is output to a user. A user response to the user question is received from the user. The user response is validated as having been provided by a human.

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.
