Meaning and Definition
The automated process of extracting data from websites, typically for aggregation, analysis, or storage.
A technique in data science and business intelligence where structured information is programmatically gathered from web pages, often involving parsing HTML, simulating user interaction, or using APIs. It exists in both legal/ethical contexts (public data collection with permission) and problematic contexts (violating terms of service, data theft).
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. Both use "web scraping." In UK contexts, "screen scraping" is sometimes used more broadly for any data extraction from visual interfaces, while US tends to reserve it for legacy systems.
Connotations
Neutral technical term in both, but carries legal/ethical weight depending on context. Slight tendency in UK English to hyphenate more often as "web-scraping" in formal writing.
Frequency
Equally common in technical and business contexts in both regions. Slightly higher frequency in US due to larger tech industry discourse.

FAQ
Frequently Asked Questions
It depends on the website's terms of service, the jurisdiction, the type of data scraped (personal data is highly regulated), and how the data is used. Publicly available data for personal, non-commercial use is often acceptable, but commercial use or scraping protected data can lead to legal action.
An API (Application Programming Interface) is a website's approved, structured way to access its data, often with rate limits. Web scraping extracts data directly from the public-facing web pages, which can be less stable (breaks if site layout changes) and may not be permitted by the site owner.
Python is the most popular due to powerful libraries like Beautiful Soup, Scrapy, and Selenium. Other languages like JavaScript (with Node.js and Puppeteer), R, and Go are also commonly used.
Technically, most public-facing websites can be scraped, but many employ anti-scraping measures like CAPTCHAs, IP blocking, requiring JavaScript execution, or obfuscating their HTML. These make scraping more difficult and may require advanced tools like headless browsers.
