Answer 1

I am using following code without any major library function for detokeization purpose. I am using detokenization for some specific tokens

_SPLITTER_ = r"([-.,/:!?\";)(])"

def basic_detokenizer(sentence):
""" This is the basic detokenizer helps us to resolves the issues we created by  our tokenizer"""
detokenize_sentence =[]
words = sentence.split(' ')
pos = 0
while( pos < len(words)):
    if words[pos] in '-/.' and pos > 0 and pos < len(words) - 1:
        left = detokenize_sentence.pop()
        detokenize_sentence.append(left +''.join(words[pos:pos + 2]))
        pos +=1
    elif  words[pos] in '[(' and pos < len(words) - 1:
        detokenize_sentence.append(''.join(words[pos:pos + 2]))   
        pos +=1        
    elif  words[pos] in ']).,:!?;' and pos > 0:
        left  = detokenize_sentence.pop()
        detokenize_sentence.append(left + ''.join(words[pos:pos + 1]))            
    else:
        detokenize_sentence.append(words[pos])
    pos +=1
return ' '.join(detokenize_sentence)
