Video description
Even though computers can't read, they're very effective at extracting information from natural language text. They can determine the main themes in the text, figure out if the writers of the text have positive or negative feelings about what they've written, decide if two documents are similar, add labels to documents, and more.
This course shows you how to accomplish some common NLP (natural language processing) tasks using Python, an easy to understand, general programming language, in conjunction with the Python NLP libraries, NLTK, spaCy, gensim, and scikit-learn. The course is designed for basic level programmers with or without Python experience.
- Gain practical hands-on natural language processing experience using Python
- Understand how to tokenize text so it can be processed as symbols
- Learn to convert text and words to vectors using TF-IDF and word2vec
- Explore dependency parsing, sentiment analysis, and LDA topic modeling
- Learn to find named entities in text and map them to an external knowledge base
- Understand the capabilities and limitations of natural language text processing
