Title:
Generating Language with Personality for Dialogue Systems
Speaker:
Professor Marilyn Walker
Department of Computer Science

Abstract:
Over the last fifty years, the ``Big Five'' model of personality
traits has become a standard in psychology, and research has
systematically documented correlations between a wide range of
linguistic variables and Big Five traits. A distinct line of research
has explored methods for automatically generating language that varies
along personality dimensions, which, in the main, has only
superficially exploited the psycholinguistic findings. In this talk, I
will briefly summarize our previous work on statistical language
generation, and then present PERSONAGE (PERSONAlity GEnerator), an
extension of previous work that implements and utilizes 67 different
parameters related to personality. I will discuss two of the methods
we have evaluated for generating personality-rich language: (1) a
rule-based approach based on findings from social psychology studies;
and (2) a statistical NLG method we call parameter-estimation, which
learns parameter settings from human judgments of personality. I will
discuss the strengths and weakness of both approaches: our evaluations
show that both methods can reliably generate utterances that humans
perceive as manifesting different personality traits.
The Dublin Computational Linguistics Research Seminar series is run
jointly by Dublin City University, Dublin Institute of Technology,
Trinity College Dublin, and University College Dublin.
The 2008/2009 DCLRS is hosted by the Computational Linguistics Group
of Trinity College Dublin, with support from the the Centre for
Computing and Language Studies, Centre for Language and Communication
Studies, the School of Computer Science and Statistics, and the Centre
for Next Generation Localisation.
