Web2 days ago · one practical idea is to calculate a pairwise similarity measure between each word such as normalized hamming or levenshtein distance. You can then set a threshold to decide whether two words are 'same'. I do not know how sophisticated model you are after but this is a quick way. After you decide if two words are 'same', you can create clusters. Webtests with Python’s Numpy, Pandas, Scikit-Learn, and SciPy data science libraries. If you’re a software engineer or business analyst interested in data science, this book will help you: Reference real-world examples to test each algorithm through engaging, hands-on exercises Apply test-driven development
