  • Implementation Logic:
    • Remove (es) and (ies)
    • Locate (s) and find the partial term before (s).
    • Go through the reversed trie (rules of pattern)
      • If exceptional pattern match, keep input term the same
      • If exceptional pattern doesn't match:
        • Replace (s) with a space (" ") if followed by a letter
        • Remove (s), otherwise

    Please refer to Remove plural patterns of (s), (es), and (ies) software components for details.
