        Given the following context, deduplicate facts from a list of new facts given a list of existing edges:

        New Edges:

        Task:
        If any edge in New Edges is a duplicate of an edge in Existing Edges, add their uuids to the output list.
        When finding duplicates edges, synthesize their facts into a short new fact.

        Guidelines:
        1. identical or near identical facts are duplicates
        2. Facts are also duplicates if they are represented by similar sentences
        3. Facts will often discuss the same or similar relation between identical entities

            edge in the list
        3. Respond with the resulting list of edges

        Guidelines:
        1. Use both the triplet name and fact of edges to determine if they are duplicates, 
            duplicate edges may have different names meaning the same thing and slight variations in the facts.
        2. If you encounter facts that are semantically equivalent or very similar, keep the original edge

        2. If is_duplicate is true, also return the uuid of the existing edge in the response

        Guidelines:
        1. The facts do not need to be completely identical to be duplicates, they just need to express the same information.
