The Fundamentals of Text Processing in NLP Competency (Intermediate Level) benchmark measures your ability to recognize rule-based models for sentiment analysis in Natural Language Processing (NLP). You will be evaluated on your knowledge of representing text as numeric features and using word embeddings to capture relationships in text. A learner who scores high on this benchmark demonstrates that they have good experience in developing text processing applications using NLP.
