Affective Computing● Refers to processing of “emotions”● Enables computers to perceive and/or

express affect● Does NOT refer to:

○ Creating emotional computers○ Introducing unreliability/unpredictability in computers

Page 5: Wordnet-Affect [IIT-Bombay]

Need of Affective Computing● Importance of emotion to humans● Vast wealth of information conveyed via

emotions [Sentic Modulation]○ Body language○ Facial expressions○ Voice cues

● Ability to enhance communication with computers

Cannot Express Can Express

Cannot Perceive Most computers today Use of smileys, etc

Can Perceive Teaching computers Maximally user-friendly*

Wordnet-Affect● Linguistic resource for affect● Wordnet-Affect = Wordnet + Affect

Information

Page 11: Wordnet-Affect [IIT-Bombay]

Need of Wordnet-Affect● Haphazard process of selecting emotion

words● Lack of emotion features● Need of distinguishing different senses of

the same word

Stages in Building Wordnet-Affect● Core [Manual]● Extension [Semi-Automatic]

Page 17: Wordnet-Affect [IIT-Bombay]

Building Wordnet-Affect:Core● Manual resource called Affect created with

1903 terms (not synsets)● Each term was given associated affect

information● Information was then projected from the

terms to Wordnet synsets

Page 18: Wordnet-Affect [IIT-Bombay]

Building Wordnet-Affect:Extension● Extension was performed using the following

Wordnet relations (similar to Sentiwordnet):○ Direct antonymy○ Similarity○ Derived from○ Pertains to○ Attribute○ Also see

Page 19: Wordnet-Affect [IIT-Bombay]

Building Wordnet-Affect:Extension● For other relations, similar expansion was

performed, but the synsets had to be filtered manually.○ Hypernym of ‘cheer’ is ‘attribute’○ Hyponym of ‘murder’ is ‘tyrannicide’
