Semantic partitioning.

Semantic partitioning for two entity semantic groups - “Financial Institutions” and “Financial Context” - and three document semantic groups - “day 1”, “day 2” and “day 3”. The Frobenius norms of the shaded regions quantify the cohesiveness within each semantic group, whereas the Frobenius norms of all other regions quantify the cohesiveness between pairs of semantic groups.
