BUT_SENTIMENT

Java wrapper around several sentiment analysis tools, that was created for MixedEmotions project.

REGUIREMENTS

This package requires java 1.8 and python3 ( SA_VADER ), maven for instalation and wget for downloading Sentiment140 dataset.

INSTALATION

  1. Use provided shell script to download Sentiment140 dataset needed by lingpipe.

download_datasets.sh

  1. Use maven to build jar file.

mvn install

Output of this will be two files, mefw-0.0.1-jar-with-dependencies.jar and mefw-0.0.1.jar in target directory.

USAGE

Prints help.

mefw (-h | --help)

Prints version of interface/wrapper.

mefw --version

Prints available processors.

mefw list processors

Starts up HTTP server daemon. Default port is 80.

mefw server [--port= --config= --jsonld]

Prints if text in input file was positive, neutral or negative.

mefw process [--config= --jsonld] Example: $ SA_lingpipe input.txt output.txt

PROCESSORS

Provided processors are basically wrappers around varius sentiment analysis implementations.

ADDING NEW PROCESSORS

All processors have to be stored in directory:

src/main/java/cz/vutbr/mefw/plugins Example: src/main/java/cz/vutbr/mefw/plugins/SA_lingpipe

If your processor uses additional classes, they should be stored in:

src/main/java/cz/vutbr/mefw/plugins/[name_of_processor_group] Example src/main/java/cz/vutbr/mefw/plugins/SA/

Other resources like datasets, libs, etc. belong in:

resources/[name_of_processor_group] Example: resources/but_sentiment

All processors have to be subclass of ProcessorAdapter class, which is abstract class with 3 methods. If this requirements are not met, your processor will not work.

First method is constructor with config argument. Config is used to specifi path to plugin and resources directory.

public ProcessorAdapter(Config config);

Second method is load(). This method is used to load external resources, for example datasets.

public void load();

Third method is process(String data). This method is used for actual processing of data. Method returns result of analysis, in case of sentiment analysis tool, this method returns positive, neutral or negative.

public String process(String data)
