Names in scanned legacy documents

[opensemanticsearch]

Names of Entities in old/legacy documents are often written with whitespaces like
John D O E
which should be recognized as John Doe, too.

Seems the Tesseract release 4 integrated in Apache Tika / Open Semantic ETL / Open Semantic Search recognizing such cases well, so for example "E l s e r" or "Otto S t r a s s e r" in https://commons.wikimedia.org/wiki/File:Gestapo-Akte_Georg_Elser_(Delikt).jpg is "Elser" or "Otto Strasser" in OCRd output plain text.

If there are OCR Software or yet OCRd documents where this is not the case please reopen or comment, so i can integrate some related name variant extension functions to entity extraction like:

def disjoin_chars(name):

namevariants = []

words = name.split(" ")

for i in range(len(words)):
	namevariant = " ".join(words[0:i])
	for word in words[i:]:
		if namevariant:
			namevariant += " "
		namevariant += " ".join(list(word))

	namevariants.append(namevariant)

return namevariants

generating name variants like
print(entity_manager.disjoin_chars("Georg Elser"))
['G e o r g E l s e r', 'Georg E l s e r']
