The function seems to assign values between 0 and 1 based on the degree of association with a particular concept. For example, words like "excavation" and "outdoors" have high values close to 1, indicating a strong association with the concept, while words like "shy" and "humidity" have low values closer to 0, indicating a weaker association. The function's selectivity is influenced by various factors, as different words receive different scores. It is possible that the function is selective for multiple concepts, as indicated by the range of values assigned to the words. Further testing with more diverse and random words would help in understanding the function's behavior more accurately.
