in a text such as
"The deal with Canada's Barrick Gold finalised in Toronto over the weekend"
When I try to break it into bigram model, I get this
"The deal"
"deal with"
"with Canada's"
"Canada's Barrick"
"Barrick Gold"
"Gold finalised"
"finalised in"
"in Toronto"
"Toronto over"
"over the"
"the weekend"
my question
shall I include the first word and the last word as single words
"* The"
"Weekend *"
