Learning Python: Building a Simple Customer Service LINE Bot with Embedchain
Using EmbedChain to create a customer service chatbot can be considered a demonstration of the POC concept, but if you want to officially launch it, it is recommended to use LangChain to create it through vector stores and Embedding (which is actually the method used within it). More information will be updated here gradually.

Jupyter Notebook for Java
Lately I've been working on Langgraph4J which is a Java implementation of the more famous Langgraph.js which is a Javascript library used to create agent and multi-agent workflows by Langchain. Interesting note is that [Langchain.js] uses Javascript Jupyter notebooks powered by a DENO Jupiter Kernel to implement and document How-Tos. So, I faced a dilemma on how to use (or possibly simulate) the same approach in Java and, without much hope, I started looking for a Jupyter Kernel that supported Java considering that, from the JDK 9 version, there was the introduction of JShell that enabled the REPL for Java.
