Web Scraping For Non-Programmers: Semalt Expert Explains
If you have been working with data and use the Internet as the primary source of a dataset, then you should have heard about web scraping. The web scraping starts when you are unable to extract data from the desired websites. Here we will also talk about the three tools you can use to scrape or extract the data as per your requirements.
What is web scraping? Web scraping refers to the technique or method of extracting useful information from different sites. This information can be extracted both in the text form and graphic form. Once collected, you can use the information for different purposes: from the academic research to business growth on the internet.
