line. I have done the N-gram analysis using the Text::Ngrams module in
perl which give me the frequency of each word . I am however quite
confused about the finding patterns in this text.
The tf-idf finds frequency also I presume but how does this differ
from the Ngram analysis that I did and how does the similarity measure
Please are there any perl modules or snippets of code I could get to
understand some of this concepts .
Please I am from new at this and have to do some pattern recognizing
so I am a little new to some of these , a good reference on this
topics will be appreciated.
