Based on the results of running the function on multiple inputs, here is a description of the function f(x): 

[DESCRIPTION]: The function f(x) assigns a value between 0 and 1 to each input word, where a value closer to 1 indicates a higher association with a particular concept. The function seems to be selective for multiple concepts. For example, input words like "word1" and "word3" have similar output values of 0.0675, suggesting that they are associated with the same concept. On the other hand, input word "word2" has a lower output value of 0.0206, suggesting a weaker association with that concept. Additionally, there are other input words that have output values close to 1, indicating a strong association with another concept. Overall, this function seems to be selectively associating input words with different concepts based on the output values it assigns to them.
