Web Page Data Extraction / Web Scraping
Web scraping (sometimes called harvesting) generically describes any of various means to extract content from a website over HTTP for the purpose of transforming that content into another format suitable for use in another context. Those who scrape websites may wish to store the information in their own databases or manipulate the data within a spreadsheet (Often, spreadsheets are only able to contain a fraction of the data scraped). Others may utilize data extraction techniques as means of obtaining the most recent data possible, particularly when working with information subject to frequent changes. Investors analyzing stock prices, realtors researching home listings, meteorologists studying weather, or insurance salespeople following insurance prices are a few individuals who might fit this category of users of frequently updated data.
Access to certain information may also provide users with strategic advantage in business. Attorneys might wish to scrape arrest records from county courthouses in search of potential clients. Businesses that know the locations of competitors can make better decisions about where to focus further growth. Another common, but controversial use of information taken from websites is reposting scraped data to other sites.
