Kelime frekanslarını görselleştirme

Artık durak kelimelerle ve durak kelimeler olmadan en sık geçen kelimeleri hesapladığına göre, farkları görselleştirme zamanı. Bu egzersizde, her iki durum için de çubuk grafikler çizmek üzere matplotlib kullanacaksın.

Aşağıdaki listeler senin için önceden yüklendi: top_words_without_stopwords, top_counts_without_stopwords, top_words_with_stopwords, top_counts_with_stopwords.

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.

Exercise 1: Bag-of-Words gösterimi Exercise 2: Müşteri incelemelerinden sözlük oluşturma Exercise 3: BoW ile metni sayılara dönüştürme Exercise 4: Ürün yorumlarının frekans analizi Exercise 5: Kelime frekanslarını görselleştirme
