## What it is
FNLP (FudanNLP) is a Java toolkit for Chinese natural language processing, including word segmentation, POS tagging, NER, keyword extraction, dependency parsing, text classification, and clustering, plus the underlying machine learning algorithms and datasets. The project is no longer updated; its successor is FastNLP.

## Use cases
- segment chinese text into words
- part-of-speech tagging for chinese sentences
- recognize named entities in chinese text
- dependency parsing of chinese sentences
- extract keywords from chinese documents
- classify or cluster chinese news articles
- java nlp library for chinese

## When to choose
- you need a pure-Java Chinese NLP toolkit with bundled models
- you are maintaining legacy code already built on FNLP
- you want classic statistical NLP tasks (segmentation, tagging, parsing) for Chinese

## When to avoid
- you want an actively maintained toolkit - the project is no longer updated
- you need modern deep-learning-based NLP - use its successor FastNLP instead
- you work primarily with non-Chinese languages

## Facets
- artifact type: library

- domain: machine-learning
- platform: jvm
- tags: chinese-nlp, word-segmentation, part-of-speech-tagging, named-entity-recognition, dependency-parsing, text-classification, clustering, superseded-by-fastnlp, natural-language-processing
