Orange-Textable 2.0

Textable add-on for Orange 2.7 data mining software package.

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
