Learn the tricks and tips that will help you design Text Analytics solutionsAbout This VideoIndependent solutions that will teach you how to efficiently perform Natural Language Processing in PythonUse dictionaries to create your own named entities using this easy-to-follow guideLearn how to implement NLTK for various scenarios with the help of example-rich solutions to take you beyond basic Natural Language ProcessingIn DetailNatural Language Processing (NLP) is a feature of Artificial Intelligence concerned with the interactions between computers and human (natural) languages. This course includes unique videos that will teach you various aspects of performing Natural Language Processing with NLTK—the leading Python platform for the task.In this course, you will learn what WordNet is and explore its features and usage. It will teach how to extract raw text from web sources and introduce some critical pre-processing steps. You will also get familiarized with the concept of pattern matching as a way to do text analysis.By the end of the course, you will be confident & have covered various solutions, covering natural language understanding, Natural Language Processing, and syntactic analysis.All the code and supporting files for this course are available on Github at https://github.com/PacktPublishing/Text-Processing-using-NLTK-in-Python Show and hide more
