Mengeksplorasi relasi kata dengan embeddings

Word embedding menangkap makna kata berdasarkan penggunaannya dalam himpunan data teks berukuran besar. Dengan menempatkan kata-kata yang mirip berdekatan dalam ruang vektor kontinu, embedding memungkinkan model mengenali konteks dan hubungan semantik yang tidak dapat ditangkap oleh metode yang lebih sederhana. Sekarang Anda akan bekerja dengan embedding untuk mengeksplorasi langsung jenis-jenis hubungan kata ini.

Model word embedding glove-wiki-gigaword-50 telah berhasil dimuat dan siap digunakan melalui variabel model_glove_wiki.

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.
