Example 1 with FrequencyTable

use of annis.service.objects.FrequencyTable in project ANNIS by korpling.

the class QueryServiceImpl method frequency.

/**
 * Frequency analysis.

 *                   annotation name can be set to "tok" to indicate that the
 *                   span should be used instead of an annotation.
