  • Natural language dialogue apparatus and method
    Patent number: 6466899
    Abstract: A natural language dialogue apparatus. A blank data memory stores blank data to blank a question element being a decision object for a value of truth or falsehood in a question to ask the value of truth or falsehood. If the input sentence is the question, a question data conversion section estimates the question element in the input sentence, and converts the input sentence to question data in which the question element is blanked by referring to the blank data memory. A problem solution section retrieves a solution for the question element blanked in the question data and generates a response in which an answer for the value of truth or falsehood is not included according to the solution.
