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.

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.

According to one embodiment, a topic extracting apparatus extracts each term from a target document set, and calculates an appearance frequency of each term and a document frequency that each term appears. The topic extracting apparatus acquires a document set of appearance documents with respect to each extracted term, calculates a topic degree, extracts each term whose topic degree is not lower than a predetermined value as a topic word, and calculates freshness of the extracted topic word based on an appearance date and time. The topic extracting apparatus presents the extracted topic words in order of the freshness and also presents the number of appearance documents of each presented topic word per unit span.
