我曾尝试使用 snowballc 词干分析器进行词干提取，但它会为相同的查询产生不同的输出
wordStem("waiting",language = "porter")
## [1] wait
上面的词是正确的，但是每当我给出一组标记作为输入时
c("htc", "makes", "bad", "cheap", "phones", "dont", "buy", "cheap",
"phones", "battery", "jock", "taiwanese", "buying", "htc", "desire",
"phone", "htc", "mobile", "specifications", "battery", "pick",
"low", "light", "camera", "experience", "htc", "e8", "desire",
"10", "pro", "phone", "performance", "excellent", "camera", "nice",
"model", "cam", "battery", "realy", "hand", "set", "phone", "coming",
"phone", "price", "range", "average", "performer", "worst", "battery",

"overheating", "issue", "typical", "htc", "crappy", "specs", "poo")
它输出没有变化的单词

如果有一种方法可以处理（进行词干提取）标记中的所有单词，那将会很有帮助。
