Cookbook¶

This section describes how to get a number of basic tasks done with Orange Textable. Each task is explained by means of a concise, illustrated recipe. The goal is to provide the user with a set of elementary operations which, once properly chained, may form the basic skeleton of various more ambitious projects.

Text input¶

  • Import text from keyboard
  • Import text from file
  • Import text from internet location

Text output¶

  • Display text content
  • Export text content (and/or change text encoding)

Text preprocessing and recoding¶

  • Convert text to lower or upper case
  • Remove accents from text
  • Replace all occurrences of a string/pattern

Segmentation manipulation¶

  • Segment text in smaller units
  • Merge several texts
  • Include/exclude units from a segmentation based on a pattern
  • Filter segments based on their frequency
  • Create a random selection or sample of segments
  • Exclude segments based on a stoplist
  • Convert XML tags to Orange Textable annotations

Text analysis¶

  • Count unit frequency
  • Count occurrences of smaller units in larger segments
  • Count transition frequency between adjacent units
  • Examine the evolution of unit frequency along the text
  • Build a concordance
