Advanced Web Scraping Course: Techniques and Tools for Data Extraction
Welcome to the Advanced Web Scraping course: Techniques and Tools for Data Extraction
In this course we will learn several techniques to extract data from the network and its implementation in various programming languages such as Python and PHP.
The fundamental concepts of advanced web scraping will be established. It will explain what web scraping consists of and its importance in accessing and extracting data from web pages. Key concepts such as the structure of the web, the HTTP protocol and HTML elements will be covered.
The various applications of web scraping in different industrial sectors will be explored later. It will highlight how the access and analysis of web data can provide valuable information for business decision making, market research, price monitoring, trend tracking, among other practical cases.
The ethical and legal considerations associated with web scraping will be addressed. Best practices will be discussed to ensure web scraping is done responsibly, respecting the websites terms of service and privacy policies. In addition, guidelines will be provided to avoid overloading the servers and prevent crashes or restrictions.
Example projects will be developed to obtain data. More advanced cases such as data extraction from PDF files and images will be seen.
At the end of the course, a project will be proposed to be developed by the students and thus demonstrate what they have learned.
At the end of the course, students will have the course content in an ebook so that they have it at hand and can review it in the future.
Here I will put an index with the chapters of the course.
