Utilizing semantic analysis to determine how to measure affective response

A method for utilizing semantic analysis to set a measuring rate of a device that measures affective response, comprising:

• receiving a first indication derived from a first evaluation comprising semantic analysis of a first segment of content comprising data representing text;
• wherein the first evaluation comprises analysis of an aspect of a meaning of a portion of the first text;
• determining that the first indication indicates that a first value related to a prediction of emotional response to the first segment does not reach a first predetermined threshold, and configuring the device to measure, at a first measuring rate, affective response of a user to the first segment;
• receiving a second indication derived from a second evaluation comprising semantic analysis of a second segment of content comprising data representing text;
• wherein the second evaluation comprises analysis of an aspect of a meaning of a portion of the second text;
• and
• determining that the second indication indicates that a second value related to a prediction of emotional response to the second segment reaches a second predetermined threshold, and configuring the device to measure, at a second measuring rate, affective response of the user to the second segment;
• wherein while operating at the first measuring rate, the device takes at least 50% fewer measurements of affective response, per unit of measurement time, compared to measurements of affective response the device takes while operating at the second measuring rate.

A system configured to enable a device to measure affective response at varying measuring rates based on semantic analysis of content, comprising:

• a receiver configured to receive first and second indications derived from first and second evaluations comprising semantic analysis of first and second segments of content that comprise first and second data representing first and second texts, respectively;
• wherein the first and second evaluations comprise analysis of first and second aspects of meanings of first and second portions of the first and second texts, respectively;
• and wherein the first indication indicates that a first value, which is a function of emotional response the first segment, does not reach a first predetermined threshold, and the second indication indicates that a second value, which is a function of emotional response to the second segment, does reach a second predetermined threshold;
• a processor configured to select, based on the first and second indications, first and second measuring rates for measuring affective response, respectively;
• and
• a controller operable to configure the device to measure the affective response of a user according to the first and second measuring rates;
• wherein while operating at the first measuring rate, the device takes at least 50% fewer measurements to measure affective response of the user to the first segment, per unit of measurement time, compared to measurements the device takes while operating at the second measuring rate to measure affective response of the user to the second segment.
