This chapter will introduce you to NLP, some of its use cases such as named-entity recognition and AI-powered chatbots. You’ll learn how to use the powerful spaCy library to perform various natural language processing tasks such as tokenization, sentence segmentation, POS tagging, and named entity recognition.

Exercise 1: Natural Language Processing (NLP) basics Exercise 2: Doc container in spaCy Exercise 3: NER use case Exercise 4: Tokenization with spaCy Exercise 5: spaCy basics Exercise 6: Running a spaCy pipeline Exercise 7: Lemmatization with spaCy Exercise 8: Sentence segmentation with spaCy Exercise 9: Linguistic features in spaCy Exercise 10: POS tagging with spaCy Exercise 11: NER with spaCy Exercise 12: Text processing with spaCy

Learn about linguistic features, word vectors, semantic similarity, analogies, and word vector operations. In this chapter you’ll discover how to use spaCy to extract word vectors, categorize texts that are relevant to a given topic and find semantically similar terms to given words from a corpus or from a spaCy model vocabulary.

Exercise 1: Fitur linguistik Exercise 2: Anotasi linguistik di spaCy Exercise 3: Disambiguasi makna kata dengan spaCy Exercise 4: Dependency parsing dengan spaCy Exercise 5: Pengantar word vector Exercise 6: Kosakata spaCy Exercise 7: Vektor kata dalam kosakata spaCy Exercise 8: Vektor kata dan spaCy Exercise 9: Analogi dan operasi vektor
