We adapted Robert Plutchiks model of emotions to Internet chat,
and chatter-robot
systems. We created an emotional chat application in witch the two conversational
partners had to label their sentences with Plutchiks 24 basic emotions.
Each partner saw
the emotional label her partner assigned to her message. We examined the
distribution of
basic emotions in the dialogue logs and how the emotional load of the
sentences changed
during the conversation. In the paper we try to approach empathy as altering
ones emotion
in response to the partners change of her label. We designed a visualization
software to
display personal emotion changes in Plutchiks 3 dimensional cone
model as a function
of time. This way we can follow the trajectory of the emotional state
of the person as the
current active emotion is moving on the surface of the cone during the
discussion. We
also developed another software based on Plutchiks circumplex model,
which displays the
two conversational partners emotions on a series of circles placed
one above the other as
they followed each other in the discourse. This way the emotional loads
of the sentences
resemble a double chain of a DNA molecule, where the two sides are the
two dialogue
partners, and the distance between two consecutive points is the distance
between the
two partners consecutive sentences in the discussion. With the help
of these tools we can
visualize the changes of emotional load in a discussion, and calculate
several statistical
parameters which can describe empathy in the discussion. We also used
these tools to build
an expression-emotion database, which we used up to identify the emotional
load of user
sentences in human computer interactions with our chatter-robot system.
