While Web Scraping can be used to build the data sets that will be analyzed via Data Mining, they still stand as separate processes.

Web Scraping vs API

Lastly, Web Scraping is often also confused with APIs. After all, they do refer to very similar processes.

An API (Application Programming Interface) refers to a set of procedures and protocols that allow for the access of data from a specific database. For example, a weather forecast agency can build an API for news agencies and developers to access weather data and build their own tools or content.

In cases where an API might not be available, a web scraper can help you in accessing the data you want via extraction.
