Data scraping, also known as web scraping or data harvesting, is the process of extracting information from websites or other sources of data using automated tools or software programs. This technique is commonly used in the field of data analytics and research to gather large amounts of data quickly and efficiently. The data extracted through scraping can include text, images, videos, or any other content available on the internet. The scraped data can then be used for various purposes such as analysis, machine learning, or building applications that require large datasets. However, it is important to note that data scraping may be illegal or unethical in some cases, especially when it involves personal or confidential information.
