*The package is a natural language processing package which allows one to
summarize text by finding*
*- relevant sentences*
*- relevant keywords*
This is done by constructing a sentence network which finds how sentences
are related to one another (word overlap). On that network Google Pagerank
is used in order to find relevant sentences.
In a similar way 'textrank' can also be used to extract keywords. How? A
word network is constructed by looking if words are following one another.
On top of that network the 'Pagerank' algorithm is applied to extract
relevant words. Relevant words which are following one another are next
pasted together to get keywords.
