Auto Text Summarization
About papers, I would like to add to the previous answer next ones:

"Text Data Management and Analysis" by ChengXiang Zhai and Sean Massung, chapter 16.
"Texts in Computer Science: Fundamentals of Predictive Text Mining" by Sholom M. Weiss, 
Nitin Indurkhya and Tong Zhang (second edition), chapter 9.
I have decided to develop a Auto Text Summarization Tool using Python/Django. 
Can someone please recommend books or articles on how to get started? 
Is there any open source algorithm or made project in the Auto Text Summarization so that I can gain the idea? 
Also, would you like to suggest me the new challenging FYP for me in Django/Python?
