Text Summarization models

if you are able to endorse me on Arxiv, i would be more than glad https://arxiv.org/auth/endorse?x=FRBB89 thanks This repo is built to collect multiple implementations for abstractive approaches to address text summarization , for different languages (Hindi, Amharic, English, and soon isA Arabic)

If you found this project helpful please consider citing our work, it would truly mean so much for me

it is built to simply run on google colab , in one notebook so you would only need an internet connection to run these examples without the need to have a powerful machine , so all the code examples would be in a jupiter format , and you don't have to download data to your device as we connect these jupiter notebooks to google drive

• Arabic Summarization Model using the corner stone implemtnation (seq2seq using Bidirecional LSTM Encoder and attention in the decoder) for summarizing Arabic news
• implementation A Corner stone seq2seq with attention (using bidirectional ltsm ) , three different models for this implemntation
• implementation B seq2seq with pointer genrator model
• implementation C seq2seq with reinforcement learning

Try out this text summarization through this website (eazymind) , which enables you to summarize your text through

• curl call

curl -X POST 
http://eazymind.herokuapp.com/arabic_sum/eazysum
-H 'cache-control: no-cache' 
-H 'content-type: application/x-www-form-urlencoded' 
-d "eazykey={eazymind api key}&sentence={your sentence to be summarized}"

• python package (pip install eazymind) pip install eazymind

from eazymind.nlp.eazysum import Summarizer

#---key from eazymind website---
key = "xxxxxxxxxxxxxxxxxxxxx"

#---sentence to be summarized---
sentence = """(CNN)The White House has instructed former
    White House Counsel Don McGahn not to comply with a subpoena
    for documents from House Judiciary Chairman Jerry Nadler, 
    teeing up the latest in a series of escalating oversight 
    showdowns between the Trump administration and congressional Democrats."""
    
summarizer = Summarizer(key)
print(summarizer.run(sentence))

Implementation A (seq2seq with attention and feature rich representation)

contains 3 different models that implements the concept of hving a seq2seq network with attention also adding concepts like having a feature rich word representation This work is a continuation of these amazing repos

Model 1

is a modification on of David Currie's https://github.com/Currie32/Text-Summarization-with-Amazon-Reviews seq2seq

Model 2

1- Model_2/Model_2.ipynb

a modification to https://github.com/dongjun-Lee/text-summarization-tensorflow

2- Model_2/Model 2 features(tf-idf , pos tags).ipynb

a modification to Model 2.ipynb by using concepts from http://www.aclweb.org/anthology/K16-1028

Results

A folder contains the results of both the 2 models , from validation text samples in a zaksum format , which is combining all of

• bleu
• rouge_1
• rouge_2
• rouge_L
• rouge_be for each sentence , and average of all of them

Model 3

a modification to https://github.com/thomasschmied/Text_Summarization_with_Tensorflow/blob/master/summarizer_amazon_reviews.ipynb

Implementation B (Pointer Generator seq2seq network)

it is a continuation of the amazing work of https://github.com/abisee/pointer-generator https://arxiv.org/abs/1704.04368 this implementation uses the concept of having a pointer generator network to diminish some problems that appears with the normal seq2seq network

Model_4_generator_.ipynb

uses a pointer generator with seq2seq with attention it is built using python2.7

zaksum_eval.ipynb

built by python3 for evaluation

Results/Pointer Generator

• output from generator (article / reference / summary) used as input to the zaksum_eval.ipynb
• result from zaksum_eval

i will still work on their implementation of coverage mechanism , so much work is yet to come if God wills it isA

Implementation C (Reinforcement Learning For Sequence to Sequence )

this implementation is a continuation of the amazing work done by https://github.com/yaserkl/RLSeq2Seq https://arxiv.org/abs/1805.09461

Model 5 RL

this is a library for building multiple approaches using Reinforcement Learning with seq2seq , i have gathered their code to run in a jupiter notebook , and to access google drive built for python 2.7

zaksum_eval.ipynb

built by python3 for evaluation

Results/Reinforcement Learning

• output from Model 5 RL used as input to the zaksum_eval.ipynb
