2. PROBLEM STATEMENT
“Personality Recognition” includes automatic classification of authors’
personality traits, that can be compared against gold standard annotation
obtained by means of the big5 personality test.
5. INTRODUCTION
• Mapping personality of person to big-5 personality traits which includes:
Extraversion – (sociable vs shy)
Neuroticism – (neurotic vs calm)
Agreeableness - (friendly vs uncooperative)
Conscientiousness - (organized vs careless)
Openness - (insightful vs unimaginative)
6. DATA SET
• Facebook dataset of 250 users of about 10000 status.
• Essay dataset of about 2400 essays
9. FEATURE EXTRACTION
• Style based features
• Sentimental Analysis
• Total number of posts of author
• Concept Extraction
• Social networking features
11. • Extroverts tend to use
• Dictionary words
• 2nd person,3rd person singular
• Past tense verbs
• Neurotic users tend to
• Update their status with anger words and
• Less likely to use social interaction words
14. APPROACH-2
Trigram based approach
• It is based on generating two features for each status say F1 and F2
• Where F1– represents normalized frequency of trigrams w.r.t to
current personality trait
• And F2 – represents normalized frequency of trigrams w.r.t remaining
classes
• Finally train the individual classifier using SVM for feature vector
(F1,F2)
