Systems and methods for document generation

A method for document generation, comprising:

• identifying, by a style extractor, a document fragment including a first style element to be preserved and a second style element to be modified, wherein the first style element corresponds to a first style category and the second style element corresponds to a second style category different from the first style category;
• generating, by a style generator, a graph based on a plurality of style element clusters from a plurality of historical document fragments including the historical document fragment;
• performing, by the style generator, a tree search based on the graph;
• selecting, by the style generator, a modified second style element of the second style category based on a reward function and the tree search, wherein the reward function is computed based on a correlation value between the first style category and the second style category, and wherein the correlation value is an indication of a visual consistency based on a probability that a style element of the first style category and a style element of the second style category are both included in a historical document fragment;
• and
• generating, by a document generator, a modified document fragment comprising at least a portion of a media file including the first style element corresponding to the first style category and the modified second style element of the second style category.

An apparatus for document generation, comprising:

• a style extractor configured to extract a first style element of a first style category from a document fragment;
• a style generator configured to:
• compute a reward function based on a correlation value between the first style category and a second style category,
• generate a graph based on a plurality of style element clusters from a plurality of historical document fragments including the historical document fragment,
• perform a tree search based on the graph, and
• select a second style element of the second style category based on the reward function and the tree search, wherein the correlation value is an indication of a visual consistency based on a probability that a style element of the first style category and a style element of the second style category are both included in a historical document fragment;
• and
• a style recommender configured to identify a recommended fragment comprising at least a portion of a media file including the first style element of the first style category and the second style element of the second style category.
