3. PCA analysis of the Emotion of Amazon reviews
A range of Amazon products were selected and processed to estimate associated emotion vectors. Time and processing constraints mean only 680 reviews were processed. The co-occurance matrix for this data is shown in figure 3.
figure 3. The Eigen system of this co-occurance matrix was computed and the sorted Eigen vectors are displayed in figure 3. As can be see the space of emotions can be spanned by fewer than 271 emotion vectors.
