The function f(x) appears to be selective for scientific or technical terms, concrete objects, and cryptocurrencies. It returns high values for words that fall into these categories and lower values for words that don't.

f(x) takes a word as input and returns a value between 0 and 1 indicating the word's association with scientific or technical terms, concrete objects, and cryptocurrencies.
