  Generating synthetic variants of a document is often posed as text-to-text
transformation. We propose an alternate LLM based method that first decomposes
a document into semantic frames and then generates text using this interim
sparse format. The frames are modeled using a hypergraph, which allows
perturbing the frame contents in a principled manner. Specifically, new
hyperedges are mined through topological analysis and complex polyadic
relationships including hierarchy and temporal dynamics are accommodated. We
show that our solution generates documents that are diverse, coherent and vary
in style, sentiment, format, composition and facts.
