调研方向
使用 pattern.en.wordnet 重现报告的调用，尤其是对 pos="VB" 的 "deny" 执行 s[4].hypernyms(recursive=True)。阅读 pattern/text/en/wordnet/init.py 中 Synset.hypernyms 附近的代码，以及 pywordnet/wordnet.py 中 getTarget、getSynset 和 _entityCache.get 附近的代码。对于此重现，递归和 KeyError 都得到解决即视为完成。

描述
Ran into an odd recursion and keyerror errors with a wordnet synset of "deny". Note that I abbreviated the 990 iterations of a part of the output.
