Plutchik's wheel organizes affect into eight primary emotions in four opposing pairs: joy ↔ sadness, trust ↔ disgust, fear ↔ anger, and surprise ↔ anticipation. Each emotion varies in intensity and can blend with its neighbours to form dyads (e.g. joy + trust = love).
This taxonomy is a popular, granular scheme for emotion/sentiment annotation. Tag spans where the subject expresses an emotion in their own words and assign the primary emotion (optionally with an intensity). Emotion words that appear only in the interviewer's question are not coded.
