Abstract: According to one embodiment, an action history search device receives an inquiry from a user and outputs a inquiry time and a target of inquiry, decides a range for searching action history information representing history of the user's action together with a time of the user's action using the target of inquiry, and calculates an elapsed time from the time of the user's action within the range to the inquiry time. The device judges using the elapsed time and a narrowing-down model a probability on each response candidate to the inquiry based on the history of the action within the range. The narrowing-down model is used for judging according to the elapsed time the probability that the response candidate to the inquiry obtained from the history of the action is the user's desired response. The device outputs the response candidate according to the probability.

The information processing apparatus includes a measurement unit, an estimation unit, an extraction unit, and a display unit. The measurement unit is configured to measure a present location and an acceleration representing a rate of a specific user's move. The estimation unit is configured to estimate a moving status of the specific user based on the acceleration, and to estimate a line information which the specific user is presently utilizing or will utilize based on the present location and the moving status. The extraction unit is configured to extract at least one utterance information related to the line information from the server. The display unit is configured to display the utterance information extracted.

Abstract: According to one embodiment, an action history search device receives an inquiry from a user and outputs a inquirty time and a target of inquiry, decides a range for searching action history information representing history of the user's action together with a time of the user's action using the target of inquiry, and calculates an elapsed time from the time of the user's action within the range to the inquiry time. The device judges using the elapsed time and a narrowing-down model a probability on each response candidate to the inquiry based on the history of the action within the range. The narrowing-down model is used for judging according to the elapsed time the probability that the response candidate to the inquiry obtained from the history of the action is the user's desired response. The device outputs the response candidate according to the probability.

Abstract: External data acquired via an input device during display of presentation information on a display device is recorded, and feature amounts are calculated from the external data. An importance level is calculated by integrating the feature amounts for each section during the display period of the presentation information. First headline information of a part of the presentation information corresponding to a section having an importance level which exceeds a predetermined threshold is generated, and is presented to be aligned along the time axis. Previous display contents of the presentation information are searched for in response to a selection operation of the first headline information, and are displayed on the display device. Second headline information of a part of the presentation information corresponding to the section when the selection operation was made is generated, and is presented on the display device.

Abstract: A context estimation rule is applied to spare time on a user's schedule, and contexts are estimated. On the basis of a task template, an input task is divided into plural subtasks. A task recommendation rule for recommending tasks to do from the relation between contexts and metadata of tasks is applied to the spare time of the user, and tasks to do in the spare time are recommended on the basis of the contexts of the spare time and the metadata of the subtasks. The recommended tasks are managed as schedules.

Abstract: An information displaying apparatus includes a presentation displaying unit that displays presentation information on a display unit, a pointing-input receiving unit that receives a pointing to the display unit, a pointing-area detecting unit that detects a pointing area with respect to a predetermined coordinate area including the displayed presentation information, an attention-area determining unit that determines an attention area with respect to the presentation information based on the detected pointing area and an attention-area determination rule, and a highlight displaying unit that displays the determined attention area in a highlighting manner with respect to the presentation information.

Abstract: A conference supporting apparatus acquires structured data recorded with conference content in time series, and acquires information input during a conference. Keywords are extracted from the structured data and the input information. An abstract level of each of the keywords is specified in accordance with predetermined rules. Importance level of each of the keywords is calculated based on the input information. Finally, a heading for each of the abstract levels is specified from the keywords based on the importance levels.

Abstract: A method is for operating a boiler to heat a bioreactor with gases produced from the bioreactor, while supplying excessive hot water to outside of a system. In the method, the boiler is operated to turn on and off depending upon temperature of a hot water tank when a level of a gas holder is higher than an intermediate level H.sub.1. Hot water is unconditionally supplied to the outside of the system when the level of the gas holder is higher than a high level H.sub.2, and hot water is supplied to the outside when temperature of the hot water tank is higher than an intermediate temperature L.sub.1 and the level of the gas holder is between the high level H.sub.2 and the intermediate level H.sub.1. The supply of the hot water is stopped when the level of the gas holder is less than the intermediate level H.sub.1.
