* Big-5 personality trait questionnaire:

	- Prompt: "Below is a number of personality traits that may or may not apply to you. Please
	indicate the extent to which you agree or disagree with the statements. You should rate the
	extent to which a pair of traits applies to you even if one trait applies more strongly than
	the other. I see myself as..."

	- Statements:

		Extraverted, enthusiastic (1)
		Critical, quarrelsome (2)
		Dependable, self-disciplined (3)
		Anxious, easily upset (4)
		Open to new experiences, complex (5)
		Reserved, quiet (6)
		Sympathetic, warm (7)
		Disorganized, careless (8)
		Calm, emotionally stable (9)
		Conventional, uncreative (10)

	- 5 point scale (1: Strongly disagree to 5: Strongly agree) was used.

	- Each Big-5 trait is assessed above with 2 questions using "opposite scales". For example,
	  "Extraversion" is assessed on "the positive" (Extraverted, enthusiastic) and "the negative"
	  (Reserved, quiet) scales. In our experiments, we merge such question pairs via
	  (positive + (6 - negative)) / 2, and work with five Big-5 features.
