... vectors. This is called global clustering. Since (by looking at differential vectors) their algorithm al- lows a word to belong to more than one cluster, each cluster a word is assigned to ... clustering of global co-occurrence vectors. To see this, let us bring our attention to the various species of ani- mals that are among the top 30 associations to poach. Some of them se...
