Hi,

Does any one know how to tokenize a string in python that returns the
byte offsets and tokens? Moreover, the sentence splitter that returns
the sentences and byte offsets? Finally n-grams returned with byte
offsets.

Input:
This is a string.

Output:
This 0
is 5
a 8
string. 10


thanks

Like this?

py> import re
py> s = "This is a string."
py> for g in re.finditer("\S+", s):
.... print g.group(), g.start()
....
This 0
is 5
a 8
string. 10

Hi,

Thanks. Can you please tell me how to do for n-grams and sentences as
well?
