Spaces are not always sufficient to tokenize English language text comprehensively. While spaces are a common delimiter, they may not accurately capture all linguistic nuances, especially in cases like contractions and compound words. Tokenization involves breaking down a text into its individual units or tokens.
Consider the example sentence: “I can’t believe how well-prepared she is for the presentation.”
If we rely solely on spaces for tokenization, we might end up with tokens like “can’t” and “well-prepared” being treated as single units. However, a more accurate tokenization would separate “can’t” into “can” and “not,” and “well-prepared” into “well” and “prepared.”
