Document classification is the process of organizing documents into predefined categories based on their content. This helps in managing large volumes of information efficiently, making it easier to retrieve and analyze data. For example, a company might classify documents into categories like invoices, contracts, and reports to streamline their workflow. Using techniques from machine learning and natural language processing, automated systems can classify documents quickly and accurately. These systems analyze the text within documents to determine their category, reducing the need for manual sorting. This not only saves time but also enhances productivity in various fields, including legal, healthcare, and finance.
