A Python library and CLI tool for automatic text summarization using extractive methods like LexRank, LSA, Luhn, and Edmundson.
Sumy is a Python library and command-line tool for automatic text summarization of text documents and HTML pages. It implements extractive summarization methods like LexRank, LSA, Luhn, and Edmundson to condense content while preserving key information. The package includes an evaluation framework to measure summary quality and supports multiple languages.
Developers and researchers working with natural language processing who need to automatically generate summaries from web content, documents, or other text sources. It's particularly useful for those building content analysis tools, research assistants, or automated reporting systems.
Sumy provides a simple, practical implementation of multiple proven summarization algorithms in a single package with both library and CLI interfaces. Unlike more complex NLP suites, it focuses specifically on extractive summarization with minimal dependencies and straightforward extensibility for new languages.
Module for automatic summarization of text documents and HTML pages.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements established extractive methods like LexRank and LSA, allowing users to experiment with different approaches for various text types, as shown in the command-line examples.
Supports multiple natural languages and provides documentation on how to add new ones via tokenizers, making it adaptable for international projects without extensive setup.
Includes tools like sumy_eval to assess summary quality against reference summaries, which is useful for research and tuning, as demonstrated in the CLI usage.
Offers a command-line interface and Docker container for quick summarization from URLs or files without deep integration, simplifying deployment and testing.
Limited to extractive summarization, which can produce less coherent or creative summaries compared to abstractive methods, and the README admits this by focusing on established algorithms without modern alternatives.
Adding support for new languages requires creating custom tokenizers, which might be challenging for non-experts or languages with limited NLP resources, despite the provided documentation.
Lacks integration with contemporary deep learning models, relying on older algorithms that may not match the performance of state-of-the-art tools for complex summarization tasks.
