Patents by Inventor Katsutoshi Ohtsuki

Katsutoshi Ohtsuki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8918408
    Abstract: A computing device maintains an input history in memory. This input history includes input strings that have been previously entered into the computing device. When the user begins entering characters of an input string, a predictive input engine is activated. The predictive input engine receives the input string and the input history to generate a candidate list of predictive inputs which are presented to the user. The user can select one of the inputs from the list, or otherwise continue entering characters. The computing device generates the candidate list by combining frequency and recency information of the matching strings from the input history. Additionally, the candidate list can be manipulated to present a variety of candidates. By using a combination of frequency, recency and variety, a favorable user experience is provided.

  • Patent number: 8798983
    Abstract: Architecture that suppresses the unexpected appearance of words by applying appropriate restrictions to long-term and short-term memory. The quickness of adaptation is also realized by leveraging the restriction. The architecture includes a history component for processing user input history for conversion of a phonetic string by a conversion process that output conversion results, and an adaptation component for adapting the conversion process to the user input history based on restriction(s) applied to short-term memory that impacts word appearances during the conversion process. The architecture performs probability boosting based on context-dependent probability differences (short-term memory), and dynamic linear-interpolation between long-term memory and baseline language model based on frequency of preceding context of word (long-term memory).
