Abstract: According to one embodiment, a document analysis apparatus is an apparatus comprising first document storage circuit for storing first documents that include words, belong to respective categories constituting a hierarchical structure, and only comprise opinion documents for a desirable object, and a second document storage circuit for storing second documents that include words, belong or do not belong to the categories constituting the hierarchical structure and comprise opinion documents for the desirable object and documents other than the opinion documents, and the apparatus is configured to classify, into one of the categories constituting the hierarchical structure, the second documents that do not belong to the respective categories among the second documents stored in the second document storage circuit.

Abstract: According to an embodiment, a dictionary updating apparatus includes a candidate extraction unit, a selection control unit, and a word registration unit. The candidate extraction unit extracts, based on a recognition result text obtained by a voice recognition engine performing a voice recognition processing using a word dictionary and a correction result text obtained by correcting at least a part of the recognition result text, candidates of words to be additionally registered in the word dictionary. The selection control unit generates a selection screen on which the extracted candidates are displayed selectably and, at the same time, information indicating the influence on the voice recognition processing at least when the candidates are additionally registered in the word dictionary is displayed, and accepts an operation of selecting the candidates displayed on the selection screen. The word registration unit registers additionally the candidates selected on the selection screen in the word dictionary.

Abstract: An input support apparatus of an embodiment includes a template storage unit configured to store a form template that is a template for form data having one or more slots to which item values are input in correspondence with item names, the form template describing item names of the respective slots and alternatives of an alternative type slot in which an item value is selected from a plurality of alternatives together with respective readings thereof; an acquisition unit configured to acquire recognition result data obtained by speech recognition performed on utterance of a user, the recognition result data containing a transcription and a reading; and a determination unit configured to determine the item values to be input to the slots of the form data based on the reading of the recognition result data and the readings of the item names and the alternatives described in the form template.

Abstract: An information processing device according to an embodiment includes a keyword extracting unit, a tag generating unit and a UI control unit. The keyword extracting unit extracts a keyword from time-series texts within a time range set by a user. The tag generating unit generates a tag corresponding to a time period from a first appearing time until a last appearing time of a same keyword appearing plural times within a duration set according to the time range. The UI control unit creates a UI screen including a first display area in which a time axis corresponding to the time range is displayed and a second display area in which the tag is displayed while causing the tag to correspond to the time period on the time axis, and resets, by selecting the tag, a time period of the selected tag in the time range to update the UI screen.

Abstract: An information processing device includes an extracting unit, a first calculating unit, and a second calculating unit. From a sentence included in a set of sentences, the extracting unit extracts compound words, each made of a plurality of words, and first words other than the words constituting the compound words. The first calculating unit calculates, based on the occurrence frequencies of the first words and based on the occurrence frequencies of the compound words, first degrees of importance indicating the degrees of importance of the first words and the degrees of importance of the compound words. With respect to first sentences included in the set of sentences, the second calculating unit calculates second degrees of importance, which indicate the degrees of importance of the first sentences, based on the first degrees of importance of the words and the first degrees of importance of the compound words.
