1 There’s more to sentiments than you think!
Guest lecture in Muhammad Abdul-Mageed’s S604: Social Media Mining, Indiana University, March 6, 2013 By David Heise Rudy Professor of Sociology Emeritus, IU

2 Sentiment analysis assesses people’s emotionality from texts that they produce.
It answers the question: When talking about X, are people happy or unhappy? The trouble is…

3 Emotions cover a lot more territory than just happy and unhappy!
Pleasant vs. unpleasant; stillness vs. arousal; dominant vs. vulnerable. So if you assess just happiness and unhappiness, you’re missing a lot of what people are feeling and expressing in their texts.

4 There are three affective dimensions:
Badness versus Goodness (unpleasant-pleasant) Weakness versus Powerfulness (vulnerable-dominant) Quiescence versus Activation (stillness-arousal) Research projects in 30 different cultures have verified these dimensions.

The socio-emotional basis of human interaction and communication: How we construct our social world. Social Science Information, 52(1), 3–33. The three dimensions are a universal basis for how people affectively respond to all kinds of stimuli, including other people and their behaviors.

5 Measuring affective response
The affective meanings of words, phrases, pictures, sounds, or smells are measured with computerized scales, one for each dimension. I think stimulus is “being female”

6 Measurement details Each stimulus gets a three-number profile, corresponding to measurements on Evaluation, Potency, Activity (EPA). Measurements range from -4 (bad, powerless, inactive) to +4 (good, powerful, active) Stimuli typically are rated by respondents, and averages over all respondents constitute the final EPA profile.

7 Example EPA measurements of words by IU male students in 2002-2004
People Behaviors Modifiers Word E P A champion 2.4 2.5 2.2 rescuing 2.6 1.9 adventurous 2.3 grandparent 2.7 1.5 -1.0 praying with 1.8 1.7 -1.3 peaceful 2.8 -1.8 child 1.4 -0.8 2.1 lusting for 1.0 0.2 feminine 0.6 -0.4 0.0 senior citizen 1.2 -0.9 obeying -0.5 cautious -0.2 -0.7 politician fighting -1.6 2.0 enraged -1.2 executioner -2.0 incarcerating 0.7 -0.6 dogmatic 0.3 prostitute -1.9 babbling to panicked -1.7 victim -2.4 stealing from -2.9 cowardly -2.1 ±1 = slightly, ±2 = quite, ±3 = extremely

8 Good Bad champion, grandparent, child, senior citizen, rescuing, praying with, lusting for, obeying, adventurous, peaceful, feminine, cautious politician, executioner, prostitute, victim, fighting, incarcerating, babbling to, stealing from, enraged, dogmatic, panicked, cowardly These words can be used as indicators of good (favorable) versus bad (unfavorable) in sentiment analyses of social media. The same words can be used as indicators of power versus weakness. Powerful Powerless champion, grandparent, politician, executioner, rescuing, praying with, fighting, incarcerating, adventurous, peaceful, enraged, dogmatic child, senior citizen, prostitute, victim, lusting for, obeying, babbling to, stealing from, feminine, cautious, panicked, cowardly Lively Quiet champion, child, politician, prostitute, rescuing, lusting for, fighting, babbling to, adventurous, feminine, enraged, panicked grandparent, senior citizen, executioner, victim, praying with, obeying, incarcerating, stealing from, peaceful, cautious, dogmatic, cowardly And the same words can be used as indicators of activation versus passivity.

9 Setting up program Interact.
Affect control theory uses the three dimensions and a mathematized theory to predict people’s behaviors. “ACT is one of the most encompassing and precise social-psychological theories, translating … qualitative, phenomenological approaches … into an exact quantitative system with point predictions that deliver astonishing plausible results” (Scholl, 2013: 21) Setting up program Interact. Predicting behaviors. Interact is at

10 You can’t do all that with just one dimension!
With three dimensions and a mathematized theory that people maintain their sentiments about self and other, we can predict behaviors, emotions, attributions, and labelings. With one dimension, we would know that the father should do some friendly act toward his daughter. But should he rescue her, pray with her, lust for her, obey her, or what? You can’t do all that with just one dimension!

11 Where do you get the EPA data?
Suppose you want to do three-dimensional sentiment analyses. Where do you get the EPA data?

12 Getting EPAs for words in Interact.

14 Have any 3-D sentiment analyses been done? Some related research.
Heise, D. R. (1966). "Sensitization of verbal response-dispositions by n Affiliation and n Achievement." Journal of Verbal Learning and Verbal Behavior 5: Computed the distance between EPA profiles of 1,000 words and EPA profiles representing need-for-affiliation and need-for-achievement. Result: each word scored for each need. 137 Ss wrote stories in response to four pictures. Need-scores of words in an S’s stories were averaged to score the individual on each need. Results. n-affiliation: Text-based scores correlated 0.64 with standard method of scoring needs. n-achievement: Text-based scores correlated 0.36 with standard method, and 0.30 with an experimental measure of the need. Significance: text analyses, p < .001; experiment, p < .05. Anderson, C. W., and G. E.
