=== Classic Tokenizer

|
|
|
coming[1.3.0]
|
|
|
|
A tokenizer of type `classic` providing grammar based tokenizer that is
|
|
a good tokenizer for English language documents. This tokenizer has
|
|
heuristics for special treatment of acronyms, company names, email addresses,
|
|
and internet host names. However, these rules don't always work, and
|
|
the tokenizer doesn't work well for most languages other than English.
|
|
|
|
The following are settings that can be set for a `classic` tokenizer
