Based on the input-output pairs you provided, it seems that the function f(x) is selective for words related to technology, such as "CPU", "RAM", and "excavation". The output values are all between 0 and 1, indicating a degree of association with the particular concept.
Here is a more detailed description of the function:

[DESCRIPTION]: The function f(x) takes a word as input and returns a value between 0 and 1 indicating the degree of association with the concept of technology. The function is more sensitive to words directly related to technology, such as "CPU", "RAM", and "excavation", and less sensitive to words that are not directly related, such as "genome", "mountains", and "map".

Please provide more input words for me to test and further refine the description.
