# Automatic Text Summarization
## Overview
This project aims at implementing two kinds of automatic text summarization algorithms based on [TextRank](https://www.aclweb.org/anthology/W04-3252.pdf) algorithm.
### TextRank
TextRank is an unsupervised graph-based ranking model developed by Mihalcea et al., which has been applied widely into many natural language processing tasks such as keyword extraction ([TextRank](https://www.aclweb.org/anthology/W04-3252.pdf)), sentence segmentation ([Sentence-BERT](https://arxiv.org/abs/2104.08821)) etc.
The main idea behind TextRank algorithm is based on [PageRank](https://en.wikipedia.org/wiki/PageRank), which ranks webpages by considering how many links each webpage has as well as how important each link source page is.
In TextRank algorithm for text summarization task:
* Each sentence in input document is represented as one vertex/node.
* Edges between sentences represent similarity between them.
* In order to extract summary sentences from document graph according to sentence importance scores calculated by TextRank algorithm:
* First calculate similarity matrix between all sentences.
* Then construct document graph using similarity matrix.
* Next calculate importance score for each sentence vertex/node based on PageRank algorithm.
* Finally extract summary sentences according scores.
### LexRank
LexRank is another unsupervised graph-based ranking model proposed by Erkan et al., which aims at extracting summaries based on eigenvector centrality algorithm rather than PageRank algorithm.
### Implementations
The implementations include two parts:
* **sentence_segmentation.py**: implement sentence segmentation task using Sentence-BERT model.
* **text_summarization.py**: implement text summarization task using TextRank/LexRank algorithm.
## Requirements
* python >= 3.x
* torch >=1.x
* transformers >=4.x
## Usage
### Sentence Segmentation
python
from sentence_segmentation import SentenceSegmenter
# create object
segmenter = SentenceSegmenter()
# get segmented sentences
segmented_sentences = segmenter.segment(text)
### Text Summarization
python
from text_summarization import LexSummarizer
from sentence_segmentation import SentenceSegmenter
# create object
summarizer = LexSummarizer()
# create object
segmenter = SentenceSegmenter()
# get segmented sentences
segmented_sentences = segmenter.segment(text)
# get summary sentences
summary_sentences = summarizer.summarize(segmented_sentences)
