Tokenization is the process of dividing text into individual pieces called tokens. These can be words, phrases, or even entire sentences. Proper tokenization provides the backbone for any text analysis effort.

Lemmatization vs. Stemming

  • Stemming: Reducing words to their root form. For example, “running” and “runner” may both be reduced to “run”. This technique may not yield real words.

  • Lemmatization: More sophisticated than stemming, lemmatization converts words to their dictionary form. For example, “better” becomes “good”.

Example of Tokenization, Lemmatization, and Stemming

Here’s how to leverage NLTK for these tasks:

python
from nltk.stem import PorterStemmer
from nltk.stem import WordNetLemmatizer

stemmer = PorterStemmer()
lemmatizer = WordNetLemmatizer()

text = “running runners ran”

tokens = word_tokenize(text)

stemmed_tokens = [stemmer.stem(word) for word in tokens]
print(“Stemmed:”, stemmed_tokens)

lemmatized_tokens = [lemmatizer.lemmatize(word) for word in tokens]
print(“Lemmatized:”, lemmatized_tokens)
