  • Patent number: 7805303
    Abstract: A question answering system includes a question input unit, a search unit, an answer candidate extraction unit, an answer candidate inspection unit and an answer output unit. The search unit executes search processing based on an input question. The answer candidate extraction unit extracts an initial answer candidate based on a result of the search processing. The answer candidate inspection unit inspects the initial answer candidate. The answer candidate inspection unit executes search processing with using a query including the initial answer candidate. The answer candidate inspection unit determines whether each word of a sentence obtained as a result of the search processing has a similar lexical meaning to that of each word of the input question. The answer candidate inspection unit selects an initial answer candidate contained in a query determined to have the similar lexical meaning, as a secondary answer candidate.

  • Patent number: 7738737
    Abstract: An image processing apparatus sequentially reduces a document, while changing the reduction factor step-by-step. Next, the image processing apparatus refers to the characters that constitute the document that has been reduced with the respective reduction factors, and specifies a reduction factor at which blank regions surrounded by line portions that express each character do not disappear. When an appropriate reduction factor is specified, the image processing apparatus specifies a resolution of the characters for that reduction factor, and converts the resolution of the document data to that specified resolution. Then, the image processing apparatus performs various processing for the document data whose resolution has been converted. Thus the resolution of document data is converted such that the document is reduced with a reduction factor suitable for computer processing.

  • Patent number: 7623716
    Abstract: A translation device analyses image data that includes characters, to separate and extract a character region, and another region whose structural elements differ from those of the character region; recognizes characters in the region determined to be the character region; extracts a character string related to the other region, from a result of the character recognition, to associate the character string with the character region from which the character string is extracted and the other region; translates the resulting recognized characters; and, based on the association between the character string and the other character region, pastes the resulting translation that includes the character string onto the same page as the other region that is associated with the character string.
