Knowledge Representation: Graphs or Tables?

In this article I dig into the question of whether you should use a traditional RDBMS (Postgres, MySQL etc.) or a graph database (Neo4J, AWS Neptune, OrientDB etc.) as you embark on your next data management and knowledge representation project, especially in this era of Knowledge Graphs and LLMs.

Knowing the strengths and weaknesses of each will help you pick the right tool for the job.

Text to Knowledge Graph

All the cool kids are converting natural language text to knowledge graphs, so why not me!? 😊

In this article I show how to use a “1-liner” using Concerto Graph to create nodes and edges in a Knowledge Graph from text, whilst ensuring that the nodes and edges conforms to a Concerto data model (schema).

Knowledge Graphs: Question Answering

Over the past few weeks I’ve been researching, and building a framework that combines the power of Large Language Models for text parsing and transformation with the precision of structured data queries over Knowledge Graphs for explainable data retrieval.

In this third article of the series (one, two) I will show you how to combine structured and unstructured semantic queries, and use LLMs to orchestrate question answering over a knowledge graph.

Knowledge Graphs: Chat With Your Data

This is a continuation of my previous article on creating a Knowledge Graph in 100 lines of code. In this article I will show you how you can use the “chat with your data” paradigm to convert natural language to graph queries, including using semantics search over vector embeddings.
