Formasaurus tells you the types of HTML forms and their fields using machine learning

Project description

PyPI Version Build Status Code Coverage Documentation

Formasaurus is a Python package that tells you the type of an HTML form and its fields using machine learning.

It can detect if a form is a login, search, registration, password recovery, “join mailing list”, contact, order form or something else, which field is a password field and which is a search query, etc.

    • docopt: 0.4.0

    • requests: 1.0.0

    • tldextract: 1.2.0

    • with-deps extra dependencies:

      • joblib: 1.2.0

      • lxml: 4.4.1

  • is the new code repository, replacing

  • Updated the CI configuration and development tooling.

0.8.1 (2018-07-02)

  • Support for scikit-learn < 0.18 is dropped;

  • Formasaurus is no longer tested with Python 3.3;

  • tests are fixed to account for upstream changes; Python 3.6 build is enabled.

0.8 (2016-05-24)

  • more annotated data for captchas;

  • formasaurus init command which trains & caches the model.

0.7.2 (2016-04-18)

  • pip bug with pip install formasaurus[with-deps] is worked around; it should work now as pip install formasaurus[with_deps].

0.6 (2016-01-27)

  • fields=False argument is supported in formasaurus.extract_forms, formasaurus.classify, formasaurus.classify_proba functions and in related FormFieldClassifier methods. It allows to avoid predicting form field types if they are not needed.

  • formasaurus.classifiers.instance() is renamed to formasaurus.classifiers.get_instance().

  • Bias is no longer regularized for form type classifier.

0.5 (2015-12-19)

This is a major backwards-incompatible release.

  • Formasaurus now can detect field types, not only form types;

  • API is changed - check the updated documentation;

  • there are more form types detected;

  • evaluation setup is improved;

  • annotation UI is rewritten using IPython widgets;

  • more training data is added.

0.2 (2015-08-10)
