The function f(x) appears to be selective for the concept of written or printed works, with "literature" and "reading" having high values close to 1, indicating a strong association. However, it also exhibits some selectivity for other concepts, as "Pulitzer Prize" and "Buckingham Palace" have relatively high values, albeit not as high as "literature." It does not show significant association with concepts related to mourning, musical instruments like guitars, or technical terms like CPU and television.
