Abstract: There is provided an information processing apparatus including a setting unit that sets a search character string, a searching unit that searches information including the set search character string, and a determining unit that extracts a co-occurrence character string candidate group other than partial character strings appearing as only a part of other partial character strings, among all partial character strings appearing in a plurality of pieces of the information obtained as a search result, and determines a co-occurrence character string from the co-occurrence character string candidate group, on the basis of the extracted co-occurrence character string candidate group and kinds of characters used in characters before and after the co-occurrence character string candidate group.

Abstract: The present technique relates to a control device, a control method, a recording device, a recording method, and a program, which enable recording of all episodes of a series program. A control device of a first aspect of the present technique includes an acquisition unit that acquires information of a program recorded in a recording device and a control unit that controls recording in the recording device so that an unrecorded episode is recorded when there is the unrecorded episode in a series program recorded in the recording device. The present technique can be applied to recording equipment.

Abstract: Disclosed herein is an information processing apparatus including: a sensor information acquisition section configured to acquire sensor information outputted from a sensor for detecting a user motion and sensor information outputted from a sensor for obtaining a user current location; an action pattern detection block configured to analyze sensor information indicative of a user motion to detect an action pattern corresponding to the acquired sensor information from a plurality of action patterns obtained by classifying user's actions that are executed in a comparatively short time; a keyword conversion block configured to convert, on the basis of the sensor information indicative of a current location, the information into at least one keyword associated with the current location; and a text extraction block configured to extract a text for user presentation from a plurality of texts on the basis of the detected action pattern and the generated at least one keyword.

Abstract: There is provided an information processing apparatus including an evaluation value calculating unit that acquires time-series data of a discrete system including sampling values xi in a measurement period i, calculates a movement deviation vt based on a movement mean mt of N sampling values xt, xt?1, xt?2, . . . , and xt?N+1 corresponding to predetermined periods before a predetermined measurement period t, and calculates an evaluation value st showing a rapid change in the time-series data of the discrete system in the measurement period t, on the basis of the movement deviation vt corresponding to the measurement period t and a movement deviation vt?1 corresponding to a measurement period t?1.
