Application ID: 14227020

Base Claim:
1. A system configured to use semantic analysis to measure affective response at varying measuring rates, comprising: a semantic analyzer configured to receive a first segment of content comprising data representing first text; the semantic analyzer is further configured to utilize semantic analysis to generate a first feature that describes an aspect of a meaning of a portion of the first text; the semantic analyzer is further configured to generate, based on the first feature, a first indication that a first value related to a predicted emotional response to the first segment does not reach a first predetermined threshold; and a controller configured to select, based on the first indication, a first measuring rate for a device for measuring affective response of a user to the first segment; the semantic analyzer is further configured to receive a second segment of content comprising data representing second text; the semantic analyzer is further configured to utilize semantic analysis to generate a second feature that describes an aspect of a meaning of a portion of the second text; the semantic analyzer is further configured generate based on the second feature a second indication that a second value related to a predicted emotional response to the second segment does reach a second predetermined threshold; the controller is further configured to select, based on the second indication, a second measuring rate for the device for measuring 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.

Claim 2:
2. The system of claim 1 , wherein the first and second predetermined thresholds represent first and second confidence levels in predictions of emotional response, respectively; and wherein the first and second values represent confidence in predictions of emotional response to the first and second segments, respectively; whereby the first measuring rate is selected when the first indication indicates that confidence in a prediction of emotional response to the first segment does not reach the first confidence level, and the second measuring rate is selected when the second indication indicates that confidence in a prediction of emotional response to the second segment does reach the second confidence level.
