1. A creation device comprising: a memory; and a processor coupled to the memory and configured to: determine an additional component serving as a component added to a second model owing to application of a module, and a modification component serving as a modified component in a third model, on the basis of the second model and the third model, wherein a condition, in at least a portion of which a wild card is described, and a first model are described in the module, the first model serving as a model when the module is applied to a model satisfying the condition and serving as a model including a variable in which a character string in a model satisfying the condition is stored, the character string corresponding to the wild card, and the third model is a model when the module is applied to the second model satisfying the condition and where a character string in the second model, which corresponds to the wild card, is stored in a variable, extract a word from the additional component and the modification component, on the basis of a word occurring in a fourth model to which a module, different from the module in which the condition and the first model are described, is applied, and the extracted word, calculate a degree indicating that the number of times the word occurs in the third model is high and indicating that the number of times the word occurs in the fourth model is low, and create, on the basis of the degree, a tag corresponding to the module in which the condition and the first model are described, the tag including a word where the number of times the word occurs in the third model is greater than or equal to a first predetermined value and the number of times the word occurs in the fourth model is less than or equal to a second predetermined value.
