This is a very basic library that allows you to perform sentiment analysis on strings using Java.
Q: What's the best way you can do sentiment analysis in Java?
A: You do it in Go, of course!
I wanted a library that does this for Java and I didn't find a good (and fast enough) one I can use. I then came across this repo which does sentiment analysis in Go. So I figured I can expose a function that uses that package and then build that file so a format which is compatible with Java.
And that is exactly what I did! Go has a great building functionality so I built the file using the c-shared flag and that gave me a .so file which I was able to use with the JNA library in Java to call the function.
The function takes a string and returns 0 if the sentiment is negative and 1 if positive.
This repo contains all the files I used in the above process, including the .so file which you can use on your own if you so desire.
I'm not sure how many people are going to use this so I'm not going to maintain it very much since I'm working on other things. Tests and a real configuration are definitely on the to-do though.
