NLTK and spaCy are two major Python libraries for NLP, widely used for basic text processing, N-gram modeling, POS tagging, and semantic analysis, as covered in the previous workshops. Workshop 5 will focus on applying these NLP techniques to two key NLP applications: text classification and sentiment analysis. TensorFlow and Keras are essential components for implementing LSTM networks, a popular type of RNN in machine learning, particularly for NLP tasks. This workshop will: (1) study text classification concepts in NLP and how spaCy NLP pipeline works on text classifier training; (2) use movie reviews as a problem domain to demonstrate how to implement sentiment analysis with spaCy; (3) introduce artificial neural networks (ANN) concepts, TensorFlow and Kera technologies; (4) introduce sequential modeling scheme with LSTM technology using movie reviews domain as example to integrate these technologies for text classification and movie sentiment analysis.

摘要

NLTK and spaCy are two major Python libraries for NLP, widely used for basic text processing, N-gram modeling, POS tagging, and semantic analysis, as covered in the previous workshops. Workshop 5 will focus on applying these NLP techniques to two key NLP applications: text classification and sentiment analysis. TensorFlow and Keras are essential components for implementing LSTM networks, a popular type of RNN in machine learning, particularly for NLP tasks. This workshop will: (1) study text classification concepts in NLP and how spaCy NLP pipeline works on text classifier training; (2) use movie reviews as a problem domain to demonstrate how to implement sentiment analysis with spaCy; (3) introduce artificial neural networks (ANN) concepts, TensorFlow and Kera technologies; (4) introduce sequential modeling scheme with LSTM technology using movie reviews domain as example to integrate these technologies for text classification and movie sentiment analysis.
