Counting the Number of Different Words in a Document

[Philippa]

Does anybody know how to count the number of differnt words used in a
document whilst using Windows 98?

Thanks

The following macro will tell you how many different words there are and the
number of times that each appears:

Sub WordFrequency()

Dim SingleWord As String 'Raw word pulled from doc
Const maxwords = 9000 'Maximum unique words allowed
Dim Words(maxwords) As String 'Array to hold unique words
Dim Freq(maxwords) As Integer 'Frequency counter for Unique
Words
Dim WordNum As Integer 'Number of unique words
Dim ByFreq As Boolean 'Flag for sorting order
Dim ttlwds As Long 'Total words in the document
Dim Excludes As String 'Words to be excluded
Dim Found As Boolean 'Temporary flag
Dim j, k, l, Temp As Integer 'Temporary variables
Dim tword As String '

' Set up excluded words
' Excludes =
"[the][a][of][is][to][for][this][that][by][be][and][are]"
Excludes = ""
Excludes = InputBox$("Enter words that you wish to exclude,
surrounding each word with [ ].", "Excluded Words", "")
' Excludes = Excludes & InputBox$("The following words are excluded:
" & Excludes & ". Enter words that you wish to exclude, surrounding each
word with [ ].", "Excluded Words", "")
' Find out how to sort
ByFreq = True
Ans = InputBox$("Sort by WORD or by FREQ?", "Sort order", "FREQ")
If Ans = "" Then End
If UCase(Ans) = "WORD" Then
ByFreq = False
End If

Selection.HomeKey Unit:=wdStory
System.Cursor = wdCursorWait
WordNum = 0
ttlwds = ActiveDocument.Words.Count
Totalwords = ActiveDocument.Words.Count

' Control the repeat
For Each aword In ActiveDocument.Words
SingleWord = Trim(aword)
If SingleWord < "A" Or SingleWord > "z" Then SingleWord = ""
'Out of range?
If InStr(Excludes, "[" & SingleWord & "]") Then SingleWord = ""
'On exclude list?
If Len(SingleWord) > 0 Then
Found = False
For j = 1 To WordNum
If Words(j) = SingleWord Then
Freq(j) = Freq(j) + 1
Found = True
Exit For
End If
Next j
If Not Found Then
WordNum = WordNum + 1
Words(WordNum) = SingleWord
Freq(WordNum) = 1
End If
If WordNum > maxwords - 1 Then
j = MsgBox("The maximum array size has been exceeded.
Increase maxwords.", vbOKOnly)
Exit For
End If
End If
ttlwds = ttlwds - 1
StatusBar = "Remaining: " & ttlwds & " Unique: " & WordNum
Next aword

' Now sort it into word order
For j = 1 To WordNum - 1
k = j
For l = j + 1 To WordNum
If (Not ByFreq And Words(l) < Words(k)) Or (ByFreq And
Freq(l) > Freq(k)) Then k = l
Next l
If k <> j Then
tword = Words(j)
Words(j) = Words(k)
Words(k) = tword
Temp = Freq(j)
Freq(j) = Freq(k)
Freq(k) = Temp
End If
StatusBar = "Sorting: " & WordNum - j
Next j

' Now write out the results
tmpName = ActiveDocument.AttachedTemplate.FullName
Documents.Add Template:=tmpName, NewTemplate:=False
Selection.ParagraphFormat.TabStops.ClearAll
With Selection
For j = 1 To WordNum
.TypeText Text:=Words(j) & vbTab & Trim(Str(Freq(j))) &
vbCrLf
Next j
End With
ActiveDocument.Range.Select
Selection.ConvertToTable
Selection.Collapse wdCollapseStart
ActiveDocument.Tables(1).Rows.Add BeforeRow:=Selection.Rows(1)
ActiveDocument.Tables(1).Cell(1, 1).Range.InsertBefore "Word"
ActiveDocument.Tables(1).Cell(1, 2).Range.InsertBefore
"Occurrences"
ActiveDocument.Tables(1).Range.ParagraphFormat.Alignment =
wdAlignParagraphCenter
ActiveDocument.Tables(1).Rows.Add
ActiveDocument.Tables(1).Cell(ActiveDocument.Tables(1).Rows.Count,
1).Range.InsertBefore "Total words in Document"
ActiveDocument.Tables(1).Cell(ActiveDocument.Tables(1).Rows.Count,
2).Range.InsertBefore Totalwords
ActiveDocument.Tables(1).Rows.Add
ActiveDocument.Tables(1).Cell(ActiveDocument.Tables(1).Rows.Count,
1).Range.InsertBefore "Number of different words in Document"
ActiveDocument.Tables(1).Cell(ActiveDocument.Tables(1).Rows.Count,
2).Range.InsertBefore Trim(Str(WordNum))
System.Cursor = wdCursorNormal
' j = MsgBox("There were " & Trim(Str(WordNum)) & " different words
", vbOKOnly, "Finished")
Selection.HomeKey wdStory

End Sub
