Abstract: An information processing device includes an acquisition unit that acquires a plurality of documents and clue information including a plurality of words and a generation processing unit that generates inter-document relationship source information based on the plurality of documents and the clue information, generates high frequency appearance information based on the inter-document relationship source information, generates vicinity appearance information based on the high frequency appearance information, and generates an inter-document relationship table based on the vicinity appearance information.

Abstract: A similar expression collecting unit (103) collects a word/phrase of an expression similar to an analysis viewpoint word/phrase and a word embedding corresponding the word/phrase from distributed representations of words data. A dimension selecting unit (104) selects a dimension of a word embedding depending on the analysis viewpoint word/phrase, and compresses a word embedding corresponding to the word/phrase collected by the similar expression collecting unit (103) in the selected dimension.

Abstract: An information processing device includes processing circuitry to acquire a signal representing voices corresponding to utterances made by one or more users; recognize the voices from the signal, convert the recognized voices into character strings to identify the utterances, and identify times corresponding to the utterances; identify users who have made the utterances, as speakers from among the users; store information including records indicating the utterances, the times corresponding to the utterances, and the speakers corresponding to the utterances; estimate meanings of the utterances; refer to the information and when a last utterance of the utterances and one or more of the utterances immediately preceding the last utterance are not a conversation, determine that the last utterance is a voice command for controlling a target; and when it is determined that the last utterance is the voice command, control the target in accordance with the meaning of the last utterance.

Abstract: A display device includes: a transmissive display unit disposed in front of the eyes of a user; an image capturing unit for capturing a real world image at an image capturing view angle larger than a display view angle of the display unit; an AR recognizing unit for recognizing an object regarding which additional information is displayed from the captured real world image; a mode determining unit for determining whether a real object superimposing mode or an image superimposing mode is applied; and a display control unit for allowing additional information regarding the recognized object to be superimposed and displayed on the real world which has transmitted through the display unit in the real object superimposing mode, and allowing the additional information regarding the recognized object to be superimposed and displayed on the captured real world image in the image superimposing mode.

Abstract: A work assistance apparatus includes a line-of-sight measuring unit configured to measure line-of-sight information about a worker, a line-of-sight movement-direction measuring unit configured to measure the direction of line-of-sight movement along a line-of-sight on the basis of the measurement result acquired by the line-of-sight measuring unit, and to output a measurement quantity of the direction of line-of-sight movement, a skill-level estimator for comparing the measurement quantity with a reference quantity prepared in advance, to estimate a skill level indicating the proficiency level of the worker on the basis of a result of the comparison, and an output controller for causing an information output unit to output work assistance information having descriptions corresponding to the skill level estimated by the skill-level estimator.

Abstract: An instruction terminal includes a position direction estimating unit to estimate a position and direction of a worker from an image captured by an imaging unit, an onsite situation image generator to generate an image indicating an onsite situation including the position of the worker from the estimation result, a display to display a screen including the generated image; a work instruction accepting unit to accept information indicating a next work position input by a work instructor on the screen; and a direction calculator to calculate a direction to the next work position from the estimation result and the acceptance result. An onsite terminal includes a guide image generator to generate an image indicating the direction to the next work position from the calculation result, and a display to display a screen including the generated image.

Abstract: A search unit 60 calculates a character-string similarity by acquiring expansion source document data partially matching a search query 70 from a character-string search index 40, determines a relational-data expansion similarity by acquiring expansion destination document data defined to have a relationship with the expansion source document data from a relational-data expansion index 50 and correcting the acquired data by the character-string similarity of the expansion destination document data and relation weight data 80, and outputs a search result 90 arranged in an order of the relational-data expansion similarity.

Abstract: A search device includes: a similar word candidate acquirer including a word dictionary searcher to perform a comparison between an input character string and word character string data, and search for word character string data similar to the input character string to acquire, as similar word candidates, the word character string data, and a number-of-similar-word-candidates controller to select similar word candidates from the similar word candidates according to a preset threshold; a similar word selector to calculate an edit distance between each of the similar word candidates selected and the input character string, and select, as a similar word, a similar word candidate whose edit distance is equal to or less than a predetermined distance; and a name searcher to refer to a name search index data storage to search for a search text including the similar word selected by the similar word selector.
