text2keywords's Introduction

text to keywords

Trained T5-base and T5-large model for creating keywords from text. Supported languages: ru

Pretraining Large version | Pretraining Base version

habr article

Usage

Example usage (the code returns a list with keywords. duplicates are possible):

Try Model Training In Colab!

pip install transformers sentencepiece
from itertools import groupby
import torch
from transformers import T5ForConditionalGeneration, T5Tokenizer
model_name = "0x7194633/keyt5-large" # or 0x7194633/keyt5-base
tokenizer = T5Tokenizer.from_pretrained(model_name)
model = T5ForConditionalGeneration.from_pretrained(model_name)

def generate(text, **kwargs):
    inputs = tokenizer(text, return_tensors='pt')
    with torch.no_grad():
        hypotheses = model.generate(**inputs, num_beams=5, **kwargs)
    s = tokenizer.decode(hypotheses[0], skip_special_tokens=True)
    s = s.replace('; ', ';').replace(' ;', ';').lower().split(';')[:-1]
    s = [el for el, _ in groupby(s)]
    return s

article = """Reuters сообщил об отмене 3,6 тыс. авиарейсов из-за «омикрона» и погоды
Наибольшее число отмен авиарейсов 2 января пришлось на американские авиакомпании 
SkyWest и Southwest, у каждой — более 400 отмененных рейсов. При этом среди 
отмененных 2 января авиарейсов — более 2,1 тыс. рейсов в США. Также свыше 6400 
рейсов были задержаны."""

print(generate(article, top_p=1.0, max_length=64))  
# ['авиаперевозки', 'отмена авиарейсов', 'отмена рейсов', 'отмена авиарейсов', 'отмена рейсов', 'отмена авиарейсов']

Training

To teach the keyT5-base and keyT5-large models, you will need a table in csv format, like this:

KeyT5 models were trained on ~7000 compressed habr.com articles. data.csv collect.py Exclusively supports the Russian language!

Some text that is fed to the input The text that should come out
