KoalaNLP is a Java/Kotlin/Scala library providing a unified interface for various Korean natural language processing (NLP) analyzers.

KoalaNLP is a library designed to simplify Korean text processing by offering a consistent interface for multiple Korean morphological and syntactic analyzers. It integrates various popular analyzers like Hannanum, Kkma, Komoran, Open Korean Text, SEunjeon, Arirang, RHINO, Daon, Khaiii, and UTagger, allowing developers to use them interchangeably with minimal code changes. The library handles complex configurations and model installations automatically, as models are distributed via Maven. KoalaNLP aims to standardize the output and execution methods of different NLP models according to government and related agency standards. This standardization enables developers to build applications that are independent of the specific underlying NLP model. It supports development across multiple programming languages including Java, Kotlin, Scala, Python 3, and NodeJS, ensuring code consistency across different environments.

Key Features

Sentence splitting

Pros

Provides a consistent interface for various Korean NLP tools.
Simplifies setup and usage by automating model distribution.
Reduces development complexity with standardized output.
Supports multiple programming languages.
Integrates a wide range of established Korean NLP analyzers.

Cons

Some analyzers (Khaiii, UTagger) require separate C++ installations.
Certain analyzers (Arirang, RHINO, Daon, Kkma, Hannanum) are not on Maven repository and require 'assembly' classifier.
UTagger requires paid commercial agreement for commercial use.
ETRI Open API requires separate key issuance and agreement.
Open Korean Text and SEunjeon may have Scala usage limitations due to their dependencies.

Use Cases
