GDEX is an abbreviation for “Good Dictionary EXamples”. It is a system for evaluation of sentences with respect to their suitability to serve as dictionary examples. When GDEX is on, good dictionary example candidates will be displayed first in a concordance making it easy for lexicographers to identify suitable example sentences in a corpus.

To make the concordance result screen display only good dictionary examples:

  • Select a corpus and make a concordance.
  • Click above the concordance lines.
  • Specify how many sentences should be sorted using GDEX.
  • If more than one GDEX configuration is available for the selected corpus a drop down list is shown to select the configuration. The configuration selected at this place is also used for sorting sentences in TickBox Lexicography (TBL).

The manual for GDEX. explains how to develop GDEX configurations for your specific needs.
