Description of the Bug
Inside the inner loops of build_graph, the code explicitly queries NetworkX using if graph.has_node(...) and if graph.has_edge(...) before manipulating node and edge data structures. While functional, explicitly checking for presence before querying or assigning properties introduces unnecessary operational lookup overhead on heavy graphs, running a secondary hash lookup on every single iteration across thousands of elements.
Steps to Reproduce
Feed a significantly large text document payload broken into hundreds of dense chunks.
Profile execution runtimes inside the nested loops of build_graph.
Observe time allocation bottlenecks stemming from redundant lookups on existing node and edge configurations.
Expected Behavior
The system should leverage more idiomatic, high-performance patterns. For nodes, lookups can be streamlined using direct attribute checking or standard dictionary fallbacks. For edge generation, standard edge handling patterns should be used to minimize redundant lookups inside tight $O(N^2)$ loops.
