Beschreibung

This learning path provides a comprehensive introduction to text mining techniques, focusing on practical implementation using Python. It covers essential steps from text preprocessing, such as lower case conversion, punctuation removal, stopword elimination, tokenization, stemming, and lemmatization, to advanced topics like Bag-of-Words, TF-IDF, Part-of-Speech tagging, Word2Vec, Doc2Vec, sentiment analysis, Latent Semantic Analysis, and Latent Dirichlet Allocation. Learners will gain hands-on experience with various text mining concepts and their application in Python.
