The main steps in Part-of-Speech (POS) tagging in NLP are as follows: First, text preprocessing is performed, which includes cleaning the text and breaking it into sentences. Second, tokenization is applied to split sentences into individual words or tokens. Third, a tagset selection is made (such as the Penn Treebank tagset) to define the grammatical categories to be assigned. Fourth, the tagging process is carried out using a method like rule-based tagging, statistical models (e.g., Hidden Markov Models), or machine learning/deep learning models. During this step, the model analyzes each word along with its context to assign the most appropriate POS tag. Finally, evaluation and refinement are performed by comparing the predicted tags with a labeled dataset to measure accuracy and improve performance.
