Title: Unsupervised Personality Recognition from Text: advantages,
disadvantages and applications
When: Tuesday Oct 8, 12 pm
Where: Serraia room, via Sommarive 14, Povo
Personality recognition from text consists in the automatic classification of
authors’ personality traits from pieces of text they wrote. Classifier’s
predictions can be compared against gold standard labels, obtained by means of
personality assessments like the Big5 personality tests. Until recently, the
extraction of personality recognition was limited to blogs and offline texts,
while now there is a strong interest in the scientific community about the
extraction of personality from various sources, like status updates in online
social networks, speech and video.
Current approaches to Personality Recognition are based on supervised learning,
but this has several limitations, for example the cost of data annotation, the
lack of domain adaptability and multilinguality. We present an unsupervised
method for personality recognition from text and some of its applications in
Social network analysis as well as in NLP tasks.
