Therefore, in this paper, we propose a method called MPM (mining perceptual map) to automatically build perceptual maps and radar charts from consumer reviews. Perceptual maps and radar charts are business tools widely used in marketing and business analysis. The proposed method may reduce subjective personal bias since perceptual maps and radar charts are mined from a large number of consumer reviews. The analysis results obtained from consumer reviews of smartphones show that the proposed method may provide some practical insights for smartphone companies. Our method can help companies position new products, and formulate effective marketing and competitive strategies. ? 2015 Elsevier B.V.
