Top Free Summarization tools, APIs, and Open Source models

What is Summarization API?

Text summarization is an NLP process that auto-generates a brief summary of lengthy documents or text. The primary objective is to condense vast amounts of data into a more manageable format while retaining the crucial and relevant details.

News articles, research papers, customer feedback, and other writing forms can be summarised using summarization APIs. They can be incorporated into diverse systems and platforms, including content management, customer relationship management (CRM), and information retrieval.

Top Open Source (Free) Summarization models on the market

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of best Summarization Open Source Models:

1‍. Text Summarizer

Text Summarizer is a complimentary and straightforward web application founded on Python and HTML that enables the user to condense any text to its fundamental key points. The application incorporates an advanced Natural Language Processing algorithm for optimum results, giving you the freedom to decide on the length of your summary.

2. SumEval

SumEval is a Python framework for text summarisation that is free and open-source. It also supports multiple languages, including Japanese and Chinese. The framework provides a well-structured JSON output that includes relevant details such as options, averages, and scores.

3. Summary

Summary is a web-based open-source application that offers extractive text summarization utilizing the frameworks of TextRank and RAKE. TypeScript and Vue were the languages employed in its creation.

4. ParaSum

ParaSum is a free, open-source, web-based tool for summarising text written in Python. It utilizes the Streamlit package to paraphrase and summarise text.

5. Sumy

Sumy is a basic library designed to extract summaries from both HTML pages and plain text documents while providing support for numerous algorithms like LSA, LexRank, Luhn, and others.

6. BERT Extractive Summarizer

This library utilizes pre-trained BERT models to carry out extractive summarization. It can be customized to specific summarization tasks, thus heightening its efficiency. This tool employs the HuggingFace Pytorch transformers library to generate extractive summaries.

The process involves embedding the sentences and subsequently applying a clustering algorithm to identify the sentences closest to the cluster's centroids.

7. Transformers

Hugging Face's Transformers library offers pre-trained models for various NLP tasks, such as summarization. BART, T5 and GPT-2 models can be utilized for both extractive and abstractive summarisation.

Cons of Using Open Source AI models

‍While open source models offer many advantages, they also come with some potential drawbacks and challenges. Here are some cons of using open source models:

  • Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear expenses related to hosting and server usage, especially when dealing with large or resource-intensive data sets.
  • Lack of Support: Open source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
  • Limited Documentation: Some open source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
  • Security Concerns: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to monitor for security updates and patches actively.
  • Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
