Question

我正在创建一个TokenRegex规则列表。这就是我所拥有的：

$STARTING_SEQUENCE = (/start/|/begin/)

{
  ruleType: "tokens",
  pattern: ([{lemma:$STARTING_SEQUENCE}]), 
  result: "START"
}

编译代码时，编译器给出了这个错误：

我做错了什么？

Answer 1

尝试

$STARTING_SEQUENCE = "/start|begin/"

因为它是匹配字符串字段引理的正则表达式，所以它需要是一个表示字符串上正常正则表达式的字符串。

您可能还想对结果执行某些操作或使用操作来执行某些注释：

示例：

{
  ruleType: "tokens",
  pattern: ([{lemma:$STARTING_SEQUENCE}]), 
  action:  ( Annotate($0, ner, "START") )
}
