![]() These elements are ranked according to their likelihood of containing relevant content. ![]() Elements with a higher ratio of text content to HTML tags are considered to be more likely to contain the main body text.īuilding a Candidate List: Based on the scores and element densities, Readability constructs a candidate list of potential main body text elements. Elements that are more likely to contain main body text, such as tags, are assigned higher scores, while elements like or tags with lower semantic significance receive lower scores.Ĭalculating Element Density: Readability measures the density of each element by analyzing the text content and HTML tags within it. These factors include the element’s tag type, class name, and other attributes. Scoring Elements: Once the HTML is parsed, Readability assigns a score to each element based on various factors. The DOM provides a hierarchical view of the HTML elements, enabling easier traversal and analysis. This step involves converting the raw HTML code into a structured representation, such as a Document Object Model (DOM). Parsing the HTML: Readability starts by parsing the HTML content of the web page using an HTML parser. The algorithm used by Readability can be summarized in the following steps: By applying a set of heuristics and analysis techniques, Readability aims to identify and extract this crucial text while discarding irrelevant elements. ![]() Readability operates on the principle that the main body text of a web page generally consists of the most prominent and informative content. It provides a simple and efficient way to extract the main body text from web pages, allowing developers and researchers to focus on analyzing the relevant content without being distracted by noise. Readability is an open-source library originally developed by Arc90 Inc. Introduction to Readabilityīefore diving into the algorithm, let’s briefly discuss what Readability is and why it’s widely used in the field of web content extraction. In this article, we will explore the algorithm used by Readability to achieve this task and gain a deeper understanding of its inner workings. One popular tool for this task is Readability, a library that aims to extract the main body text from web pages while filtering out irrelevant content such as advertisements, navigation menus, and sidebars. | Miscellaneous ⚠ content generated by AI for experimental purposes only What Algorithm Does Readability Use for Extracting Text from URLs?Īs data scientists and software engineers, we often encounter the need to extract relevant text from URLs for various applications such as web scraping, content analysis, or natural language processing.
