LangPi

It is a set of tools for language processing. It contains:

Basic language processing: Mainly, they are for preprocessing text before using it.
Normalization (norm)
Segmentation: sentence Segmentation (seg) and word tokenization (tok)
Stemming or lemmatization (stem)
Stop-words elimination (swe)
Evaluation methods: Methods for evaluating NLP systems.
Automatic text summarization: ROUGE method
Wordnet

Evaluation

Currently, there is just Rouge n-gram implementation for evaluating text summarization

Wordnet

A module for wordnet management.

Create a folder ./wordnetDB/dict and extract wordnet 3.0 files in it.

@TODO add python script to create wordnet.sqlite

To use kariminf.langpi.wordnet.WNTools.java properly, copy this folder to bin/ folder

How to compile?

Just open it using gradle and it will do what it has to be done. This project depends on many libraries:

Apache Lucene (with Snowball for stemming)
JWI (for wordnet)
Apache openNLP
sqlite-jdbc
KHebMorph (a port of HebMorph)
KJHazm (a port of JHazm)
KOpenNlp1.4 (a port of openNLP 1.4 to work alogside with ulterir versions without conflict; Thai segmentation uses it)
KToolJa (plugins management)

How to use?

You can download the jar from "release" section and link it to your project; Or you can use https://jitpack.io to manage dependency. Replace "tag" with the release tag; for example "1.1.1".

The project generates many jars; a jar for each module. So there is a way to just use one jar at a time.

Gradle

Add this to your "build.gradle":

repositories {
    ...
    maven { url 'https://jitpack.io' }
}

To download all the modules:

dependencies {
    compile 'com.github.kariminf:langpi:tag'
}

For each module:

dependencies {
    compile 'com.github.kariminf.LangPi:langpi-basic-agpl3:tag'
    compile 'com.github.kariminf.LangPi:langpi-basic-main:tag'
    compile 'com.github.kariminf.LangPi:langpi-eval:eval'
    compile 'com.github.kariminf.LangPi:langpi-wordnet:tag'
}

Release license

There are two releases:

1st: under Apache2 license; it contains most languages
2nd: under LGPL 3.0 license; it contains hebrew and thai
- The hebrew preprocessing tools set must be released under AGPL3.0, since it uses HebMorph.
- The Thai preprocessing tools set must be released under LGPL2.1, since it uses OpenNlp 1.4.2 and JWNL.
