This type of software performs computes concordances and generates text statistics. Frequently, they also allow for subsequent statistical manipulation and/or analysis.

Common Programs

• CatPac
  CatPac performs cluster analyses of textual data.
• Concordance
  Concordance's application is not language-specific. The program computes word counts and produces concordances. The resulting data might then be used for qualitative analyses or further explorations with statistical packages.
•  HAMLET
  "The main idea of HAMLET^© is to search a text file for words in a given vocabulary list, and to count joint frequencies within any specified context unit, within sentences, or as collocations within a given span of words."
• MonoConc/ParaConc
  These programs perform basic word statistics and concordances.
• T-LAB
  T-LAB computes concordances and maps document structures.
