👉 A tagger is a machine learning algorithm that processes text data and assigns tags to each word in the text. The goal of this process is to identify patterns or relationships between words within a given text, which can be used for various applications such as language modeling, sentiment analysis, and topic classification. In the context of natural language processing (NLP), taggers are often employed in natural language generation tasks like machine translation and text summarization. They are also commonly used for semantic parsing and information retrieval
