Hi Abhishek,
You need to build up your metric for "probability" first.
For e.g.,
1. keywords occurrence/total words count
2. Keywords occurrence/total sentences
3. the number of files who contain keyword / total files number

主题: [algogeeks] Probability of a phrase in a text document?
Hi,
If I have a large corpus of text documents and I need to find the
probability of occurence of a phrase like "I am" in the given set of
text documents, how do I go about finding the value?
I can very well search how many time does the phrase "I am" occurs in
the whole set of text documents including all the sentences, but what
do i divide the count by?
Thanks
With Regards,
Abhishek S
