Chia Jeng Yang introduces WhyHow.AI’s Open Source Knowledge Graph schema library. Within this schema library, you can discover a range of schemas created for various use cases in different domains, ranging from Finance to Healthcare, Manufacturing, Meeting Transcripts, and many others. You should get the most value by using the library to brainstorm and ideate the types of schemas relevant to your exact use case and industry.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:
— Purring Lynx (ℵ/acc) (@Purring_Lynx) June 29, 2024
– Uses Apache Lucene for indexing and search
– Has vector support!
– Cypher query language is awesome
I 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
