Abstract
This paper evaluates whether semantic grouping of reviews helps users make better decisions. Reviews rated as helpful were compared with semantically grouped reviews. While participants did not perceive a reduced effort (using NASA-TLX), they needed less time and performed better on answering questions about the strong,
weak and controversial points of the movies.
