Book Content

This book covers many programming topics using the Lisp language Hy that compiles to Python AST and is compatible with code, libraries, and frameworks written in Python. The main topics we will cover and write example applications for are:

• Relational and graph databases
• Web app development
• Web scraping
• Accessing semantic web and linked data sources like Wikipedia, DBpedia, and Wikidata
• Automatically constructing Knowledge Graphs from text documents, semantic web and linked data
• Deep Learning
• Natural Language Processing (NLP) using Deep Learning
• OpenAI GPT APIs
• LangChain for chaining Large Language Model operations

Please note that this repo also contains examples that are a work in progress (these directories conatin a file named NOT_YET_IN_BOOK.md).
