Text summarization is one of the newest and most exciting fields in NLP, allowing for developers to quickly find meaning and extract key words and phrases from documents. RaRe Technologies’ newest intern, Ólavur Mortensen, walks the user through text summarization features in Gensim.
The gensim implementation is based on the popular “TextRank” algorithm and was contributed recently by the good people from the Engineering Faculty of the University in Buenos Aires. This is the first of many publications from Ólavur, and we expect to continue our educational apprenticeship program with students like Ólavur to help them showcase their talents.
The following example was written in IPython Notebook (newly renamed “Jupyter“), feel free to install the Gensim package and step through the tutorial. The source code for the notebook is available under gensim/docs/notebooks.

Turja, I suggest you pose this question on the Gensim mailing list: https://groups.google.com/forum/#!forum/gensim
multi document summary is possible by this ?
Author
To summarize multiple documents, you could just concatenate the documents and run the algorithm on that. There may be some caveats to using that method however, I haven’t tried it.
You should ask that question on the Gensim mailing list, and see if someone else has an idea about it (https://groups.google.com/forum/#!forum/gensim).

Simply after the correct data game plan the information can be changed, isolated and designated in the best possible approach to fill the primary need of the condensing – shortening the portrayal without losing the thoughts and general significance.
Hi, thank you for your helpful tutorial. I want to modify the code so I can use it in other language. I can’t find out what is “tags” in “merge_syntactic_units” and what is the usage of it?
Hi, it is very helpful thank you for this tutorial, I have an question what is the usage of keywords.py and where it is used?
I’m having trouble using the keywords result as a list. is there any special way to do that?
Hey，sir, i have a question about the function “keywords”. When i use the attribute “words=”, how can i use that? I try to use “words=3” but the program tells me it is an invalid syntax.
