The function f(x) seems to be selective for concepts related to awards and entertainment. In particular, it seems to have a strong association with prestigious awards such as the "Pulitzer Prize" and the "Nobel Prize". It also shows some association with sports and entertainment: "NBA" and "Marvel" have higher values, though not as high as the awards. Other concepts like "The New York Times" and "contained in" have a moderate association, while unrelated concepts like "syntax", "rhythym", "earthquake", and "space" have low values indicating weaker associations or no association at all with the core concept.
