StringZilla can easily be 10x more memory efficient than native Python classes for tokenization. With lazy operations, it practically becomes free.import stringzilla as sz %load_ext memory_profiler text = open("enwik9.txt", "r").read() # 1 GB, mean word length 7.73 bytes %memit text....
Do not use countTokens()‘s return value to control a string tokenization loop’s duration if the loop changes the set of delimiters via a nextToken(String delim) method call. Failure to heed that advice often leads to one of the nextToken() methods throwing a NoSuchElementException object an...

Please note that there are better ways for sentence detection and tokenization using Apache OpenNLP. Check outthistutorial to learn more about the OpenNLP API. 6.

The tokenization method is much simpler than * the one used by the {@code StreamTokenizer} class. The * {@code StringTokenizer} methods do not distinguish among * identifiers, numbers, and quoted strings, nor do they recognize * and skip comments. * * The set of delimiters (the characte...
Randomized SMILES strings of molecules in the training dataset were tokenized and then fed into the encoder of the Transformer. Tokenization was conducted with the vocabulary shown in Supplementary Table1. “” and “<\s>” tokens are added to the beginning end and of the token sequences, resp...
