Detecting false intentions using unanticipated questions

Drug testing welfare recipients--false positives, false negatives, unanticipated opportunities.

Substance abuse and dependence are among the most common psychiatric disorders among pregnant and parenting women. These disorders among welfare recipients have attracted special concern. Chemical testing has been proposed to identify illicit drug use in this population. This analysis scrutinizes the potential value of drug testing, using recent data from the Women's Employment Study and the Na...

Detecting false captioning using common-sense reasoning

Detecting manipulated images has become an important problem in many domains (including medical imaging, forensics, journalism and scientific publication) largely due to the recent success of image synthesis techniques and the accessibility of image editing software. Many previous signal-processing techniques are concerned about finding forgery through simple transformation (e.g. resizing, rota...

Detecting false intent using eye blink measures

Eye blink measures have been shown to be diagnostic in detecting deception regarding past acts. Here we examined-across two experiments with increasing degrees of ecological validity-whether changes in eye blinking can be used to determine false intent regarding future actions. In both experiments, half of the participants engaged in a mock crime and then transported an explosive device with th...

Intentions, Information, And Inference: Two Rhetorical Questions

Intentions, Implicatures And Processing Of Complex Questions

In this paper we introduce two methods for deriving the intentional structure of complex questions. Techniques that enable the derivation of implied information are also presented. We show that both the intentional structure and the implicatures enabled by it are essential components of Q/A systems capable of successfully processing complex questions. The results of our evaluation support the c...
