Question

我正在使用 OpenNLP 1.5.3 ，我想在英文文本中为位置名称执行NER。为此，我从下一个URL下载了相应的模型（en-ner-location.bin）：

http://opennlp.sourceforge.net/models-1.5/

问题在于，当我尝试使用此模型使用以下命令在文本中执行NER时：

./Opennlp/bin/opennlp TokenNameFinder en-ner-location.bin < Text.txt > Text.txt.ner_en_loc

我收到以下错误：

Loading Token Name Finder model ... failed
IO error while loading model file 'en-ner-location.bin'

我的命令是否有问题，或者这是OpenNLP 1.5.3中此模型的错误？

Answer 1

文件已损坏。我再次下载它，一切正常。
