8. A method for generating a documentary of a source document comprising: receiving the source document, wherein the source document includes source content; determining a source document structure based on an automated analysis of a table of contents (ToC) of the source document, wherein determining the source document structure includes determining a plurality of hierarchical structures of the source content and an arrangement order of the plurality of hierarchical structures of the source content; segmenting the source content into a plurality of hierarchical slices based on the source document structure, wherein each of the plurality of hierarchical structures of the source content is included in one or more of the plurality of hierarchical slices and each of the plurality of hierarchical slices includes at least a rank and an index, wherein the rank represents a level of depth in the determined plurality of hierarchical structures and the index represents an ordered position in the determined arrangement order of the plurality of hierarchical structures; generating a coding map that provides a map between the rank of each of the plurality of hierarchical slices, the index of each of the plurality of hierarchical slices, and a logical location of the slice; generating one or more presentation slides for each of the plurality of hierarchical slices based on the coding map; populating each of the one or more presentation slides for each of the plurality of hierarchical slices with a portion of the source content corresponding to the hierarchical slice based at least on the rank and the index of each of the plurality of hierarchical slices; and generating a target document that includes at least a portion of the populated one or more presentation slides for each of the plurality of hierarchical slices, wherein the target document includes the documentary of the source document.

The method of claim 8 , further comprising: generating audible narration for at least a portion of textual content included in the source content; and updating at least one of the one or more presentation slides that includes the portion of the textual content to include the audible narration.
