问题描述
我正在寻找Java中的一个好的开源。这是我到目前为止所提出的。
I'm looking for a good open source POS Tagger in Java. Here's what I have come up with so far.
- LingPipe
- Stanford
- LBJ
- FastTag
有人有任何建议吗？
推荐答案
你在找吗？标记特定域中的POS？大多数通用标记符都是通过新闻专线文本进行培训的。通常，当您在特定域（例如生物医学文本）中使用它们时，它们表现不佳。还有其他专门为这些领域培训过的标记，例如非常好，是我推荐的。
For newswire text, Adwait Ratnaparkhi's MXPOST is very good and is the one I would recommend.
其他Java实现包括：
Other Java implementations include:
- （不是真正的POS标记器，但所有完整的解析器通常都包含POS标记器.Google用于 Java语法分析器，你会发现很多。）
- MontyLingua
- Berkeley Parser (Not really a POS tagger but all full blown parsers will typically include POS taggers. Google for Java syntactic parsers and you will find many.)
- QTag
- LBJ
和已发布通过其他海报也相当不错。
OpenNLP and Lingpipe as posted by the other posters are also pretty decent.
有关POS标签最新技术的信息可以找到。如您所见，（另一张海报也提到）排名最佳现在，但各种标签的变化并不多。我自己没有使用过LTAG。
Info on the state-of-the-art on POS tagging can be found here. As you can see LTAG-Spinal (also mentioned by another poster) ranks best as of now, but the variation across the various taggers is not much. I have not used LTAG myself.
另请注意，POS标记的基准性能约为90％。基线意味着 - （a）用词典中最频繁的POS标签标记每个单词，（b）将每个未知单词标记为名词。
Also note that the baseline performance for POS tagging is about 90%. Baseline means - (a) tag every word by most frequent POS tag from a lexicon, and (b) tag every unknown word as a noun.
