# Extractive text summarization
various ways to summarise text using the libraries available for Python
 1. pyteaser
 2. sumy
 3. gensim
 4. pytldr
 5. XLNET
 6. BERT
 7. GPT2
 
## INSTALL
pip install sumy 
pip install gensim 
pip install pyteaser 
pip install pytldr 
pip install bert-extractive-summarizer 
pip install spacy==2.0.12 
pip install transformers==2.2.0 
 
## Pyteaser
Pyteaser has two function: 
 Summarize: that takes title and text and summarizes them 
 SummarizeURL: that takes the url and summarizes the content of the url 
 
## Sumy
Summy has various preprocessing libraries and summarizer libraries 
 sumytoken: for tokenizing the text 
 get_stop_words: to remove the stop words from the text 
 stemmer: to stemp the words 
 LexRankSummarizer: summarizes based on lexical ranking 
 LsaSummarizer: summarizes based on semantic 
 LuhnSummarizer: summarizes based on Luhn's algorithm

## Gensim
 gensim has a summarize library which can be imported and used directly.
 
## pytldr
 pytldr is also like sumy where they have various nlp libraries like tokenizer. 
 Here we have used TextRankSummarizer, RelevanceSummarzer, LsaSummarizer from pytldr

## XLNET
XLNet is an auto-regressive language model which outputs the joint probability of a sequence of tokens based on the transformer architecture with recurrence.

## BERT
Extractive Text summarization refers to extracting (summarizing) out the relevant information from a large document while retaining the most important information. BERT (Bidirectional Encoder Representations from Transformers) introduces rather advanced approach to perform NLP tasks.

## GPT2
GPT-2 model with 1.5 Billion parameters is a large transformer-based language model. It's trained for predicting the next word. So, we can use this specialty to summarize the data.

## PS:
If you are using python2, please run main.py from "for_python2" folder 
elif you are using python3, please run main.py from "for_python3" folder 
else you can test by running "various_ways_to_summarize.py" or the notebook named as "Text Summarizer Notebook.ipynb"
