摘要
We show that the dynamic burstiness of word occurrence in textbook systems is attributed to the modularity of the word association 網絡s. At first, a measure of dynamic burstiness is introduced to quantify burstiness of word occurrence in a textbook. The advantage of this measure is that the dynamic burstiness is decomposable into two contributions: one coming from the inter-event variance and the other from the memory effects. Comparing 網絡 structures of physics textbook systems with those of surrogate random textbooks without the memory or variance effects are absent, we show that the 網絡 modularity increases systematically with the dynamic burstiness. The intra-connectivity of individual word representing the strength of a tie with which a node is bound to a module accordingly increases wit
