James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist with broad interests [ 1][ 2] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations ...
In the social sciences people sometimes use the term semantic network to refer to co-occurrence networks. [38] [39] The basic idea is that words that co-occur in a unit of text, e.g. a sentence, are semantically related to one another.
