Additionally, sports like "basketball" and sports-related terms like "coach", "athlete", "competition" and "championship" showed relatively higher values as compared to other random words. Some locations such as "New York", "London", and "Tokyo" had moderately higher values as well. The function f(x) seems to be measuring the degree of association between the input words and the combined concepts of sports and certain locations.
