The Stylometric Processing of Sensory Open Source Data
This research project’s end goal is on the Lone Wolf Terrorist.
The project uses an exploratory approach to the
self-radicalisation problem by creating a stylistic fingerprint
of a person's personality, or self, from subtle characteristics
hidden in a person's writing style. It separates the identity of
one person from another based on their writing style. It also
separates the writings of suicide attackers from ‘normal'
bloggers by critical slowing down; a dynamical property used to
develop early warning signs of tipping points. It identifies
changes in a person's moods, or shifts from one state to another,
that might indicate a tipping point for self-radicalisation.
Research into authorship identity using personality is a
relatively new area in the field of neurolinguistics. There are
very few methods that model how an individual's cognitive
functions present themselves in writing. Here, we develop a
novel algorithm, RPAS, which draws on cognitive functions such as
aging, sensory processing, abstract or concrete thinking through
referential activity emotional experiences, and a person's
internal gender for identity. We use well-known techniques such
as Principal Component Analysis, Linear Discriminant Analysis,
and the Vector Space Method to cluster multiple
anonymous-authored works. Here we use a new approach, using
seriation with noise to separate subtle features in individuals.
We conduct time series analysis using modified variants of 1-lag
autocorrelation and the coefficient of skewness, two statistical
metrics that change near a tipping point, to track serious life
events in an individual through cognitive linguistic markers.
In our journey of discovery, we uncover secrets about the
Elizabethan playwrights hidden for over 400 years. We uncover
markers for depression and anxiety in modern-day writers and
identify linguistic cues for Alzheimer's disease much earlier
than other studies using sensory processing. In using these
techniques on the Lone Wolf, we can separate their writing style
used before their attacks that differs from other writing
