What PyPLN is

PyPLN is a platform for processing and extracting useful information from text. It was conceived to run in the cloud, scale quickly and be easy to use. It integrates many text mining and natural language processing tools, which can be acessed via an easy-to-use Web interface, where you can manage documents, corpora and interact with its analysis/visualizations.

As its main feature, you can visualize analysis like part-of-speech tags, word frequency statistics and other useful information. It also offers a full-text search on your corpora so you can easily find information and then visualize its analysis.

PyPLN is developed by a research group called Núcleo de Análise e Modelagem de Dados (aka NAMD) located on Applied Mathematics School at Fundação Getúlio Vargas (in Rio de Janeiro, Brazil).

For more information, please check the project documentation.

Try our Demo

Do you want to try PyPLN without needing to install it? Register a username and start using it free (as in free beer) right now:

Note that this is just a demo installation and sometimes we need to migrate or delete data for testing new features (the project is in active development). So, do not rely on this demo to store your documents and create analysis on top of it (we advise you to install a instance in your own infrastructure).

Interact with the Community

One of the most valuable characteristics in free/libre software projects is the collaboration that comes from the community. Join our discussions, suggest new features and stay in touch through:
