Worthäufigkeiten visualisieren

Nachdem du die häufigsten Wörter mit und ohne Stoppwörter berechnet hast, ist es Zeit, die Unterschiede zu visualisieren. In dieser Übung verwendest du matplotlib, um für beide Fälle Balkendiagramme zu erstellen.

Die folgenden Listen wurden für dich vorab geladen: top_words_without_stopwords, top_counts_without_stopwords, top_words_with_stopwords, top_counts_with_stopwords.

Verwende plt.bar(), um die Top-10-Worthäufigkeiten mit Stoppwörtern zu plotten.
Verwende plt.bar(), um die Top-10-Worthäufigkeiten ohne Stoppwörter zu plotten.

Interaktive praktische Übung

Versuche dich an dieser Übung, indem du diesen Beispielcode vervollständigst.

import matplotlib.pyplot as plt
# Plot the frequencies with stop words
plt.bar(____, ____)
plt.title("Top 10 word frequencies (with stop words)")
plt.xlabel("Words")
plt.ylabel("Frequency")
plt.show()

# Plot the frequencies without stop words
plt.figure()
plt.bar(____, ____)
plt.title("Top 10 word frequencies (without stop words)")
plt.xlabel("Words")
plt.ylabel("Frequency")
plt.show()

Learn the essentials of text processing in Natural Language Processing (NLP). Master techniques such as tokenization, stop word and punctuation removal, and text normalization with lowercasing, stemming, and lemmatization to prepare text data for further analysis and insight extraction.

Exercise 1: Introduction to natural language processing Exercise 2: Sentence and word tokenization Exercise 3: NLP workflow Exercise 4: Stop words and punctuation handling Exercise 5: Removing stop words Exercise 6: Removing punctuation Exercise 7: Text normalization techniques Exercise 8: Lowercasing Exercise 9: Stemming Exercise 10: Lemmatization

Transform raw text into powerful numerical features. Create Bag-of-Words and TF-IDF representations to capture word importance across documents, then explore word embeddings like Word2Vec and GloVe to uncover deep semantic patterns. Visualize frequency, relevance, and similarity to bring your text data to life.
