This document provides an overview of the ontology related modules, their purposes and the key functionalities they handle.

OntologyResolver

1. OntologyResolver class: Implements the rdf_xml connection logic and contains the following steps

• Utility functions to handle the lookup table, such as:
  • build_lookup: Creates a lookup from the ontology
  • refresh_lookup: Updates lookup with the latest ontology changes
• Node - Ontology matching logic:
  • find_closest_match: Finds the closest ontology node to the parameter (entity — individual, entity_type — class)
• Ontology subgraph collection logic:
  • get_subgraph: Collects the subgraph starting from the closest ontology node match

2. expand_with_nodes_and_edges: Implements the main graph matching logic

• The task creates the entities and entity types from the documentchunks, looks for matching ontology nodes using the OntologyResolver class, and merges the structure of the matching ontology subgraphs with the LLM generated structures.
