Verificando a correção gramatical

Um app educacional está sendo desenvolvido para ajudar usuários a melhorar sua gramática. Um recurso central verifica automaticamente se as frases enviadas pelos usuários são gramaticalmente aceitáveis. Você foi convidado a implementar esse recurso usando um modelo treinado no Corpus of Linguistic Acceptability (CoLA) para classificar a correção de frases.

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 representation Exercise 2: Building vocabulary from customer reviews Exercise 3: Transforming text to numbers with BoW Exercise 4: Frequency analysis of product reviews Exercise 5: Visualizing word frequencies Exercise 6: TF-IDF vectorization Exercise 7: TF-IDF representation of product feedback Exercise 8: Comparing BoW and TF-IDF representations Exercise 9: Embeddings Exercise 10: Exploring word relationships with embeddings Exercise 11: Visualizing and comparing word embeddings

Harness the power of pre-trained models to perform advanced text classification tasks. Use Hugging Face pipelines for sentiment analysis, topic classification, and natural language inference. Evaluate semantic similarity and grammatical correctness with state-of-the-art models, all without building anything from scratch.

Exercise 1: Pipelines do Hugging Face para análise de sentimento Exercise 2: Analisando o sentimento de uma avaliação Exercise 3: Classificação em lote de várias avaliações Exercise 4: Comparando modelos em dados de avaliações rotuladas Exercise 5: Classificação zero-shot e QNLI Exercise 6: Classificação zero-shot de tickets de suporte Exercise 7: O texto responde à pergunta?Exercise 8: Similaridade de perguntas e correção gramatical Exercise 9: Detectando perguntas duplicadas Exercise 10: Verificando a correção gramatical
