Welcome to This Week in Neo4j, your weekly fix for news from the world of graph databases!
This week, we have our monthly Podcast with Oleg Šelajev – Neo4j Ninja and speaker at NODES. Additionally, we look at an Open Source Knowledge Graph schema library, learn how to convert text to Cypher and build a chatbot with LangChain.

For Graph Database Beginners, I picked the Cypher Aggregations course this week. This one is a bit more advanced, but if you followed this segment for a while, I am sure you can do it!

TEXT2CYPHER: Convert Text to Neo4J Cypher Using LLM – Install Locally
This video by Fahd Mirza shows a step-by-step process to install the text2cypher model locally. This is based on Tomaz Bratanic’s finetuned Llama3-Instruct:8b to generate Neo4j Cypher statements based on the GPT-4o synthetic dataset.
PYTHON: Build an LLM RAG Chatbot With LangChain/
In this tutorial by Harrison Hoffman, you’ll step into the shoes of an AI engineer working for a large hospital system. You’ll build a RAG chatbot in LangChain that uses Neo4j to retrieve data about the patients, patient experiences, hospital locations, visits, insurance payers, and physicians in your hospital system.
POST OF THE WEEK: Purring Lync
Apparently, all you need is Neo4j DB:
– Uses Apache Lucene for indexing and search
– Has vector support!
– Cypher query language is awesomeI don’t think I’ll ever use MySQL or NoSQL anymore, since you can use a graph database as a relational DB or document store. pic.twitter.com/aiWsMtbyhd
