The attempt to spot deception through its correlates in human
behavior has a long history. Until recently, these efforts have
concentrated on identifying individual "cues" that might occur with
deception. However, with the advent of computational means to
analyze language and other human behavior, we now have the ability
to determine whether there are consistent clusters of differences
in behavior that might be associated with a false statement as
opposed to a true one. While its focus is on verbal behavior, this
book describes a range of behaviors-physiological, gestural as well
as verbal-that have been proposed as indicators of deception. An
overview of the primary psychological and cognitive theories that
have been offered as explanations of deceptive behaviors gives
context for the description of specific behaviors. The book also
addresses the differences between data collected in a laboratory
and "real-world" data with respect to the emotional and cognitive
state of the liar. It discusses sources of real-world data and
problematic issues in its collection and identifies the primary
areas in which applied studies based on real-world data are
critical, including police, security, border crossing, customs, and
asylum interviews; congressional hearings; financial reporting;
legal depositions; human resource evaluation; predatory
communications that include Internet scams, identity theft, and
fraud; and false product reviews. Having established the
background, this book concentrates on computational analyses of
deceptive verbal behavior that have enabled the field of deception
studies to move from individual cues to overall differences in
behavior. The computational work is organized around the features
used for classification from -gram through syntax to
predicate-argument and rhetorical structure. The book concludes
with a set of open questions that the computational work has
generated.
