  • Publication number: 20220237536
    Abstract: A risk estimation apparatus includes: an extraction unit that extracts a factor information, which is a statistic of a physical and mental information about a factor that causes a change in work stress of a subject person, from a physical and mental information including at least one of a physiological information of the subject person and an inner state information indicating an inner state of the subject person estimated on the basis of the physiological information; an arithmetic unit that obtains a feature quantity in a predetermined time unit from the factor information; and an estimation unit that estimates a risk degree related to at least one of leave of absence, job separation or productivity of the subject person, by inputting the feature quantity into a predetermined learning model.

  • Publication number: 20170364854
    Abstract: The purpose of the present invention is to provide a technology which is capable of appropriately evaluating a person's conduct with respect to another person. Provided is an information processing device, comprising a recognition unit 11, a detection unit 12, and an evaluation unit 13. The recognition unit 11 recognizes an evaluation subject's conduct. The detection unit 12 detects a trigger which is a state of a person other than the evaluation subject which triggers the evaluation subject's conduct. Using the detected trigger and the result of recognition by the recognition unit 13 relating to the evaluation subject's conduct, the evaluation unit 13 evaluates the evaluation subject's conduct.

  • Patent number: 8892435
    Abstract: Provided is to a text data processing apparatus, method and program to add a symbol at an appropriate position. The apparatus according to this embodiment is a text data processing apparatus that executes edit of a symbol in input text, the apparatus including symbol edit determination means 52 that determines whether symbol edit is necessary or not based on a frequency of symbol insertion in a block consisting of a plurality of divided text; and symbol edit position calculation means 53 that calculates likelihood of the symbol edit based on likelihood of symbol insertion for a word and a distance between the symbols and calculates a symbol edit position in the block in accordance with the likelihood of symbol edit or a word in the block when the symbol edit determination means determines that the symbol edit is necessary.

  • Patent number: 8788266
    Abstract: The present invention uses a language model creation device 200 that creates a new language model using a standard language model created from standard language text. The language model creation device 200 includes a transformation rule storage section 201 that stores transformation rules used for transforming dialect-containing word strings into standard language word strings, and a dialect language model creation section 203 that creates dialect-containing n-grams by applying the transformation rules to word n-grams in the standard language model and, furthermore, creates the new language model (dialect language model) by adding the created dialect-containing n-grams to the word n-grams.

  • Publication number: 20140074475
    Abstract: There is provided a speech recognition result forming apparatus (10) including a recognition result output unit (106) that refers to character string data, which is a speech recognition result, and removes a word string of a recognition error included in the character string data from the character string data and also, when attached word strings are located before and/or after the word string of the recognition error, generates preformatted character string data by removing at least one of the attached word strings from the character string data or replacing at least one of the attached word strings with other data items and outputs the preformatted character string data.

  • Patent number: 8577679
    Abstract: Enables symbol insertion evaluation in consideration of a difference in speaking style features between speakers. For a word sequence transcribing voice information, the symbol insertion likelihood calculation means 113 obtains a symbol insertion likelihood for each of a plurality of symbol insertion models supplied for different speaking style features. The speaking style feature similarity calculation means 112 obtains a similarity between the speaking style feature of the word sequence and the plurality of speaking style feature models. The symbol insertion evaluation means 114 weights the symbol insertion likelihood obtained for the word sequence by each of the plurality of symbol insertion models according to the similarity between the speaking style feature of the word sequence and the plurality of speaking style feature models and the relevance between the symbol insertion model and the speaking style feature model, and performs symbol insertion evaluation to the word sequence.

  • Publication number: 20090313017
    Abstract: A framework in which a numerical value that represents a statistical appearance tendency of each of words in a language model is set with respect to the words not only as a constant, but also as an update function that changes in time, is included. The numerical value that represents the set statistical appearance tendency of a word is automatically updated in accordance with passage of time.
