Aspects of the invention include receiving an original work written in a first style to be transformed into a derivate work written in a second style. The transforming includes accessing a similarity data structure organized to include a phrase-similarity vector space of phrase vectors representing degrees of similarity between phrases in a corpus of works written in the second style. An original sentence of the original work that includes one or more original phrases is obtained. The original phrases are located in the phrase-similarity vector space. For each of the original phrases, a similar phrase from the phrase-similarity vector space is selected based on the selected similar phrase having a phrase-similarity index corresponding to the original phrase that is greater than a predetermined phrase-similarity index threshold. The derivative work is created by replacing the original phrases in the original work with the selected similar phrases. The derivative work is output.
