ヘブライ語の名前付きエンティティ認識に polyglot パッケージを使用しようとしています。
これは私のコードです:

# -*- coding: utf8 -*-
import polyglot
from polyglot.text import Text, Word
from polyglot.downloader import downloader
downloader.download("embeddings2.iw")
text = Text(u"in france and in germany")
print(type(text))
text2 = Text(u"נסעתי מירושלים לתל אביב")
print(type(text2))
print(text.entities)
print(text2.entities)

これは出力です：

<class 'polyglot.text.Text'>
<class 'polyglot.text.Text'>
[I-LOC([u'france']), I-LOC([u'germany'])]

英語は機能しましたが、ヘブライ語は機能しませんでした。
パッケージをダウンロードしようとしてもダウンロードしu'embeddings2.iw' なくても、次のようになります。

ValueError: Package u'embeddings2.iw' not found in index

わかった！
私にはバグのようです。
言語検出'iw'は、ヘブライ語の以前の ISO 639 言語コードである言語を定義し、に変更されました'he'。はコードをtext.entities認識しなかったiwので、次のように変更します。

text2.hint_language_code = 'he'
