This is a python implementation of TextRank for automatic keyword and sentence extraction (summarization) as done in https://web.eecs.umich.edu/~mihalcea/papers/mihalcea.emnlp04.pdf. However, this implementation uses Levenshtein Distance as the relation between text units.

This implementation carries out automatic keyword and sentence extraction on 10 articles gotten from http://theonion.com

• 100 word summary
• Number of keywords extracted is relative to the size of the text (a third of the number of nodes in the graph)
• Adjacent keywords in the text are concatenated into keyphrases
