This is Part 3 of a series on running sentiment analysis inside Neo4j. Part 1, Running Sentiment Analysis Inside Neo4j With a Java Plugin , used the VADER lexicon via a pure Java UDF – rule-based, fully local, high throughput. Part 2, Wasm Inside Neo4j: Building the Example That Didn’t Exist , embedded a Wasm runtime inside a Java UDF using wasmtime-java — sandboxed, still local, lower throughput.
