After you perform OCR recognition, you can check the recognized Characters by using the GetRecognizedCharacters Method. Also, you can check the recognized words as follows:
Dim ocrPageCharacters As IOcrPageCharacters = ocrPage.GetRecognizedCharacters()
For Each ocrZoneCharacters As IOcrZoneCharacters In ocrPageCharacters
' Show the words found in this zone. Get the word boundaries in inches
Dim words As ICollection(Of OcrWord) = ocrZoneCharacters.GetWords(ocrPage.DpiX, ocrPage.DpiY, LogicalUnit.Inch)

For each word, you can examine the properties, including which zone the word is in and the exact position of the word. You can also examine the accuracy of the word letters.
About the zone type, you can check the zone type by the checking OcrZone.ZoneType Property.
