  • Question answering with time-based weighting
    Patent number: 11734587
    Abstract: A mechanism is provided in a data processing system for question answering using time weighted evidence. The mechanism receives an input question. The mechanism determines a time focus for the input question and defines a weighting function. The weighting function is a bell curve having a peak at the time focus on a time axis. The mechanism decomposes the input question into one or more queries and applies the one or more queries to a corpus of information to obtain a set of hypothesis evidence. Each item of information within the hypothesis evidence has an associated time value. The mechanism weights the set of hypothesis evidence based on the associated time values according to the weighting function to form time weighted evidence and generates hypotheses for answering the input question based on the time weighted evidence.

  • Iterative deepening knowledge discovery using closure-based question answering
    Patent number: 10573190
    Abstract: A mechanism is provided in a data processing system for question answering using context features in closure form. The mechanism receives a function call comprising an input question and a set of non-local context evidence in closure form. The mechanism decomposes the input question into one or more queries and applies the one or more queries to a corpus of information to obtain a set of local hypothesis evidence. The mechanism generates hypotheses for answering the input question based on the local hypothesis evidence and the set of non-local context evidence.
