One of the most common ones is BeautifulSoup. There are several packages in Python that allow us to scrape information from webpages. Web scraping with BeautifulSoup in Python Once we have presented these concepts, we are ready for some web scraping! 2.

These tags are represented with the symbols (for example, a tag means a certain text is acting as a paragraph).įor example, this HTML code below allows us to change the alignment of the paragraphs:Ĭonsequently, when we visit a website, we will be able to find the content and its properties in the HTML code. To identify an element (this means, as an example, to set if some text is a heading or a paragraph) we use tags. There are a lot of different types of elements, each one with its own attributes. An element could be a paragraph, and an attribute could be that the paragraph is in bold letter.
HTML is, from a really basic point of view, composed of elements that have attributes. So, the last step before performing web scraping methods is to understand a bit of the HTML language. In the above example we can see that after disabling CSS, the content (text, images, etc…) is still there. If your answer was the HTML code, then you’re absolutely getting it. “If I want to extract the content of a webpage via web scraping, where do I need to look up?” They will allow us to create and manipulate every aspect of the design of a webpage.Īt this point, I’ll ask the following question:
Note that these three are programming languages.
JavaScript: JavaScript allows us to make the content and the style interactive. This means, it determines the style of a webpage. CSS (Cascading Style Sheets): this language allows us to set the visual design of a website. In one word, HTML determines the content of a webpage. It allows us to insert text, images and other things to our site. HTML (HyperText Markup Language): it is the standard language for adding content to a website. Google Chrome, Firefox, etc…) and access to it, what we see is the combination of three technologies: When we insert an url into the web browser (i.e. We will follow an example with the Towards Data Science webpage. If we want to be able to extract news articles (or, in fact, any other kind of text) from a website, the first step is to know how a website works. A brief introduction to webpage design and HTML Web scraping with BeautifulSoup in Pythonġ. A brief introduction to webpages and HTML. We’ll create a script that scrapes the latest news articles from different newspapers and stores the text, which will be fed into the model afterwards to get a prediction of its category. This post covers the second part: News articles web scraping. In the first article, we developed the text classification model in Python, which allowed us to get a certain news article text and predict its category with an overall good accuracy. It includes all the code and a complete report. The whole process is divided in three different posts: However, a machine learning project is much more than that: once you have a trained model, you need to feed new data to it and what is more important, you need to provide useful insights to the final user. This is achieved with a supervised machine learning classification model that is able to predict the category of a given news article, a web scraping method that gets the latest news from the newspapers, and an interactive web application that shows the obtained results to the user.Īs I explained in the first post of this series, the motivation behind writing these articles is that a lot of the articles or content published on the internet, books or literature regarding data science and machine learning models focus on the modelling part with the training data. The project involves the creation of a real-time web application that gathers data from several newspapers and shows a summary of the different topics that are being discussed in the news articles. If you have not read the first one, I strongly encourage you to do it here. #WEBSCRAPER PYTHON SQL SERIES#
This article is the second of a series in which I will cover the whole process of developing a machine learning project.
