Analogieën en vectorbewerkingen

Woordvectoren kunnen semantiek vastleggen en ondersteunen ook vectorbewerkingen en woordanalogieën. Een woordanalogie is een semantische relatie tussen een paar woorden. In deze oefening oefen je je begrip van analogieën en vectorbewerkingen.

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: Linguïstische kenmerken Exercise 2: Linguïstische annotaties in spaCy Exercise 3: Woordbetekenis-ontleding met spaCy Exercise 4: Dependency parsing met spaCy Exercise 5: Introductie tot woordvectoren Exercise 6: spaCy-woordenschat Exercise 7: Woordvectoren in de spaCy-woordenschat Exercise 8: Woordvectoren en spaCy Exercise 9: Analogieën en vectorbewerkingen

Get familiar with spaCy pipeline components, how to add a pipeline component, and analyze the NLP pipeline. You will also learn about multiple approaches for rule-based information extraction using EntityRuler, Matcher, and PhraseMatcher classes in spaCy and RegEx Python package.

Explore multiple real-world use cases where spaCy models may fail and learn how to train them further to improve model performance. You’ll be introduced to spaCy training steps and understand how to train an existing spaCy model or from scratch, and evaluate the model at the inference time.
