带有nlpnet的SRL不适用于某些句子

Question

我安装了nlpnet并下载了data。但它只适用于一些句子。我在virtualenv中使用ubuntu13.0432bits和python2.7.4。在

我在这里贴了两个例子，第一个似乎有用，第二个没有：

例1（似乎有效）：

python nlpnet-tag.py srl /path/to/nlpnet-data/
This is the first sentence of the paragraph. This is the second sentence of the paragraph.
This is the first sentence of the paragraph .
sentence
    A1: the paragraph
    A0: first
    V: sentence

This is the second sentence of the paragraph .
sentence
    A1: the paragraph
    A0: second
    V: sentence

例2（无效）：

这个句子取自CoNLL-2005 Examples

^{pr2}$

我还从python和tokenization进行了测试，但是在第二个调用arg_structures的示例中，返回一个空列表。在

我错过了什么。。。如果您能在不使用nlpnet的情况下提供解决方案，我们将不胜感激。在

谢谢

PS：我也reported this issue，但想看看有没有人帮我修一下。在

Answer 1

erickrf，包的作者，answer它：

the problem here is that the trained models from http://nilc.icmc.usp.br/nilc/download/nlpnet-data.zip were trained for Portuguese. It won't work in English.

When you get an empty arg_structures list, it means that the network didn't recognize any token as a predicate.
