Figure 5

Mountain visualization map of high-frequency keywords biclustering in documents of VTE anticoagulant. Each hill represents a cluster, the distance between the mountains indicates the similarity between clusters, the height of the slope is proportional to the similarity of keywords within the cluster, the volume is proportional to the number of keywords contained in the cluster, and the color of the peak is proportional to the internal standard deviation of the cluster. Red means low standard deviation, while blue means high standard deviation.
