Artificial word association dataset. The artificial word association dataset is a small scale network used to validate OMIM. It can be seen as a double layer network. 9 words constitute the first layer, in which the word 'day' works as a hub. The second layer consists of 8 sub-networks that center on other 8 words in the first layer, i.e., month, sunshine, camp, sleep, work, enjoy, long and sunny.
