Using LLMs to Create Knowledge Graphs From a Large Corpus of Parliamentary Debates
Learn how to leverage LLMs for building knowledge graphs from parliamentary debates, covering entity extraction, relationship mapping, RAG integration, and visualization techniques.
-
LLMs can effectively extract entities and relationships from text to create knowledge graphs, particularly excelling at entity recognition tasks
-
Knowledge graphs are ideal for representing data with many-to-many relationships between different types of entities, making querying and traversal more efficient than traditional databases
-
Graph databases store references between nodes upfront, making queries faster by eliminating the need for multiple joins, though write operations are slower
-
The RAG (Retrieval Augmented Generation) approach helps integrate private data with LLM capabilities by retrieving relevant context for queries
-
Validation and debugging of LLM-generated knowledge graphs remains challenging due to:
- Inconsistent outputs between runs
- Need for human verification
- Difficulty in constraining outputs
- Complex schema management
-
Parliamentary debate analysis revealed challenges in extracting consistent policy positions, as politicians discuss topics abstractly and change positions over time
-
Success depends heavily on high-quality prompts and clear instructions to the LLM
-
Post-processing and cleanup steps are often necessary to handle inconsistencies and ambiguous naming conventions
-
Graph representations provide more intuitive visualization and analysis of complex relationships between entities
-
Natural language interfaces (like text-to-Cypher queries) make knowledge graphs more accessible to non-technical users like journalists
