bert extractive summarizer
Small Bug
هذا الريبو هو تعميم ريبو محاضرة. تستخدم هذه الأداة مكتبة Luggingface Pytorch Transformers لتشغيل تلخيصات استخراجية. يعمل هذا من خلال تضمين الجمل أولاً ، ثم يدير خوارزمية تجميعية ، والعثور على الجمل الأقرب إلى النطاقات النقطية. تستخدم هذه المكتبة أيضًا تقنيات Coreference ، باستخدام مكتبة https://github.com/huggingface/neuralcoref لحل الكلمات في ملخصات تحتاج إلى مزيد من السياق. يمكن تعديل جشع مكتبة NeuralCoref في فئة CoreferenceHandler.
اعتبارًا من أحدث إصدار من Bert-extracted-Summarizer ، افتراضيًا ، يتم استخدام CUDA إذا كان وحدة معالجة الرسومات متاحة.

DISTILL BERT TURNICATION DEMO
pip install bert-extractive-summarizer from summarizer import Summarizer
body = 'Text body that you want to summarize with BERT'
body2 = 'Something else you want to summarize with BERT'
model = Summarizer ()
model ( body )
model ( body2 )يمكن توفير عدد الجمل كنسبة أو عدد صحيح. يتم توفير أمثلة أدناه.
from summarizer import Summarizer
body = 'Text body that you want to summarize with BERT'
model = Summarizer ()
result = model ( body , ratio = 0.2 ) # Specified with ratio
result = model ( body , num_sentences = 3 ) # Will return 3 sentences يمكنك أيضًا تلحق التضمينات الملخص للتجميع. مثال بسيط أدناه.
from summarizer import Summarizer
body = 'Text body that you want to summarize with BERT'
model = Summarizer ( 'distilbert-base-uncased' , hidden = [ - 1 , - 2 ], hidden_concat = True )
result = model ( body , num_sentences = 3 )يمكن للمرء استخدام الجملة Bert مع Bert-extraction-Summarizer مع أحدث إصدار. يستند إلى الورقة هنا: https://arxiv.org/abs/1908.10084 ، والمكتبة هنا: https://www.sbert.net/. للبدء ، قم أولاً بتثبيت Sbert:
pip install -U sentence-transformers
ثم مثال بسيط هو ما يلي:
from summarizer . sbert import SBertSummarizer
body = 'Text body that you want to summarize with BERT'
model = SBertSummarizer ( 'paraphrase-MiniLM-L6-v2' )
result = model ( body , num_sentences = 3 )تجدر الإشارة إلى أن جميع الميزات التي يمكنك القيام بها مع فئة الملخص الرئيسية ، يمكنك أيضًا القيام بها مع Sbert.
يمكنك أيضًا استرداد تضمينات التخصيص. الأمثلة أدناه:
from summarizer import Summarizer
body = 'Text body that you want to summarize with BERT'
model = Summarizer ()
result = model . run_embeddings ( body , ratio = 0.2 ) # Specified with ratio.
result = model . run_embeddings ( body , num_sentences = 3 ) # Will return (3, N) embedding numpy matrix.
result = model . run_embeddings ( body , num_sentences = 3 , aggregate = 'mean' ) # Will return Mean aggregate over embeddings. تأكد أولاً من تثبيت NeuralCoref و Spacy. تجدر الإشارة إلى أن NeuralCoref لا يعمل مع Spacy> 0.2.1.
pip install spacy
pip install transformers # > 4.0.0
pip install neuralcoref
python -m spacy download en_core_web_mdثم لاستخدام Coreference ، قم بتشغيل ما يلي:
from summarizer import Summarizer
from summarizer . text_processors . coreference_handler import CoreferenceHandler
handler = CoreferenceHandler ( greedyness = .4 )
# How coreference works:
# >>>handler.process('''My sister has a dog. She loves him.''', min_length=2)
# ['My sister has a dog.', 'My sister loves a dog.']
body = 'Text body that you want to summarize with BERT'
body2 = 'Something else you want to summarize with BERT'
model = Summarizer ( sentence_handler = handler )
model ( body )
model ( body2 ) from transformers import *
# Load model, model config and tokenizer via Transformers
custom_config = AutoConfig . from_pretrained ( 'allenai/scibert_scivocab_uncased' )
custom_config . output_hidden_states = True
custom_tokenizer = AutoTokenizer . from_pretrained ( 'allenai/scibert_scivocab_uncased' )
custom_model = AutoModel . from_pretrained ( 'allenai/scibert_scivocab_uncased' , config = custom_config )
from summarizer import Summarizer
body = 'Text body that you want to summarize with BERT'
body2 = 'Something else you want to summarize with BERT'
model = Summarizer ( custom_model = custom_model , custom_tokenizer = custom_tokenizer )

The Chrysler Building, the famous art deco New York skyscraper, will be sold for a small fraction of its previous sales price.
The deal, first reported by The Real Deal, was for $150 million, according to a source familiar with the deal.
Mubadala, an Abu Dhabi investment fund, purchased 90% of the building for $800 million in 2008.
Real estate firm Tishman Speyer had owned the other 10%.
The buyer is RFR Holding, a New York real estate company.
Officials with Tishman and RFR did not immediately respond to a request for comments.
It's unclear when the deal will close.
The building sold fairly quickly after being publicly placed on the market only two months ago.
The sale was handled by CBRE Group.
The incentive to sell the building at such a huge loss was due to the soaring rent the owners pay to Cooper Union, a New York college, for the land under the building.
The rent is rising from $7.75 million last year to $32.5 million this year to $41 million in 2028.
Meantime, rents in the building itself are not rising nearly that fast.
While the building is an iconic landmark in the New York skyline, it is competing against newer office towers with large floor-to-ceiling windows and all the modern amenities.
Still the building is among the best known in the city, even to people who have never been to New York.
It is famous for its triangle-shaped, vaulted windows worked into the stylized crown, along with its distinctive eagle gargoyles near the top.
It has been featured prominently in many films, including Men in Black 3, Spider-Man, Armageddon, Two Weeks Notice and Independence Day.
The previous sale took place just before the 2008 financial meltdown led to a plunge in real estate prices.
Still there have been a number of high profile skyscrapers purchased for top dollar in recent years, including the Waldorf Astoria hotel, which Chinese firm Anbang Insurance purchased in 2016 for nearly $2 billion, and the Willis Tower in Chicago, which was formerly known as Sears Tower, once the world's tallest.
Blackstone Group (BX) bought it for $1.3 billion 2015.
The Chrysler Building was the headquarters of the American automaker until 1953, but it was named for and owned by Chrysler chief Walter Chrysler, not the company itself.
Walter Chrysler had set out to build the tallest building in the world, a competition at that time with another Manhattan skyscraper under construction at 40 Wall Street at the south end of Manhattan. He kept secret the plans for the spire that would grace the top of the building, building it inside the structure and out of view of the public until 40 Wall Street was complete.
Once the competitor could rise no higher, the spire of the Chrysler building was raised into view, giving it the title.

هناك خدمة قارورة متوفرة و dockerfile المقابلة. تشغيل الخدمة أمر بسيط ، ويمكن القيام به على الرغم من أن Makefile مع الأوامر:
make docker-service-build
make docker-service-run
سيستخدم هذا النموذج المعتمد على Bert-Base ، والذي يحتوي على تمثيل صغير. يقبل Docker Run أيضًا مجموعة متنوعة من الحجج للنماذج المخصصة والمختلفة. يمكن القيام بذلك من خلال أمر مثل:
docker build -t summary-service -f Dockerfile.service ./
docker run --rm -it -p 5000:5000 summary-service:latest -model bert-large-uncased
يمكن أيضًا تمرير الوسائط الأخرى إلى الخادم. أدناه يتضمن قائمة الحجج المتاحة.
بمجرد تشغيل الخدمة ، يمكنك إنشاء أمر تلخيص في http://localhost:5000/summarize نقطة النهاية. تقبل نقطة النهاية هذه النص/الإدخال العادي الذي يمثل النص الذي تريد تلخيصه. يمكن أيضًا تمرير المعلمات كوسائط طلب. الحجج المقبولة هي:
