Stem dictionary

The stem dictionary, [ir_languagefiles_path]language.STM, contains the stem, which is the part of a term used in the IR indices. IR Expert considers each word to have a stem (defined in the .STM file) and many possible suffixes (defined in the .SUF file). For example: For the words go and going, “go” is the stem and “ing” is the suffix. Entries in the .STM file consist of the stem word (go) followed by a blank, and then an index entry in the suffix file (.SUF) would be “go 1“. This index indicates which suffix values are acceptable for the stem word.
