Orange Textable

Orange Textable is an open-source add-on bringing advanced text-analytical functionalities to the Orange Canvas data mining software package (itself open-source). It essentially enables users to build data tables on the basis of text data, by means of a flexible and intuitive interface. Look at the following example to see it in typical action.

Orange Textable offers in particular the following features:

  • text data import from keyboard, files, or urls
  • support for various encodings, including Unicode
  • standard preprocessing and custom recoding (based on regular expressions)
  • segmentation and annotation of various text units (letters, words, etc.)
  • ability to extract and exploit XML-encoded annotations
  • automatic, random, or arbitrary selection of unit subsets
  • unit context examination using concordance and collocation tables
  • calculation of frequency and complexity measures
  • recoded text data and table export
