A server wrapper around the Stanford CoreNLP sentiment engine.

Config

Port can be set in application.properties, by default it is set to 80, this may cause problems on some machines.

Deployment

Deployed using maven can be run with the command:

mvn spring-boot:run

Features

Server features one endpoint: /sentiment. This endpoint will respond to multiple GET parameters of lines. For example:

GET /sentiment?lines=The+movie+was+really+great.&lines=The+movie+was+really+
terrible&lines=The+movie+was+really+great.+The+movie+was+really+terrible HTTP/1.1

Responds:

{
    0: {
        sentiment: 0.8018029430617934,
        line: "The movie was really great."
    },
    1: {
        sentiment: 0.22636708981379178,
        line: "The movie was really terrible"
    },
    2: {
        sentiment: 0.5140850164377926,
        line: "The movie was really great. The movie was really terrible"
    }
}

Note the averaging of the third sentiment, this should be avoided but is available if required.
