Code for original Textrank algorithm (without similarity function optimizations)

[alkakhurana]

Hi,

Is it possible to get the python implementation of original Textrank algorithm? or
Can you suggest the changes that need to be done in the existing code for original Textrank?

I need to compare the summaries produced by both variations.

Thanks in advance

Hi,

The version that is in this repository follows the original implementation of TextRank.
You can have a look at the source code to calculate the similarities:
https://github.com/summanlp/textrank/blob/master/summa/summarizer.py#L41

The version that we added on Gensim uses the optimizations, with the Okapi BM25 function.
You can verify that in the source code in:
https://github.com/RaRe-Technologies/gensim/blob/develop/gensim/summarization/summarizer.py#L79

Best,
Fede
