An exploration on the word co-occurrence network of Chinese popular song titles

Song titles is a special form of language expression with modernity and popularity: they are short in form and concise in meaning and can reflect the ideology and values of an era. In this paper, we built a co-occurrence network with the titles of approximately six thousand Chinese popular songs. We make an all-round research about it from the perspective of complex networks and explain such characteristics as small world effect, scale-free, hierarchy, betweenness centrality and assortiveness and so on. This paper reveals the unique nature of the co-occurrence network of the titles of popular songs and broadens the scope of language network studies.
