Emerging technologies like RPA and web scrapers depend on screen-scraping to gather data from digital screens. Early screen scraping software was used to grab source code from outdated systems and move it to contemporary applications. Screen scraping, on the other hand, may extract specific data from any active program using contemporary technologies like OCR and computer vision.
We’ll look at what screen scraping is, how it works, some commercial uses, and some problems in this post.
What is a screen scraping, and how does it work?
Screen scraping, also known as terminal emulation, is the technique of gathering visual information from computer displays and autonomously inserting information into various programs or processes on the computer without the need for human participation. Screen scraping was also used to extract data from old mainframe programs (such as IBM mainframe) and show it on current PC apps (e.g. excel).
What are the benefits of screen scraping for companies?
Users may utilize screen scraping to automate rule-based, repeated data transfer procedures, which has several advantages:
- Optimize data quality by using scripts to collect and transmit data without the need for human interaction (e.g. duplicates, typos, missing data).
- Reduce the time required to process information: Screen scraping tools cut down on the time it takes to manually acquire and modify information. Screen scraping, according to UiPath, can reach 100% accuracy in data capture from various apps in as little as 16 milliseconds.
What is screen scraping and how does it work?
Screen scrapers are programs that are programmed to do the following:
- Look for and locate user-specified UI items retrieve information from user-specified Ui components (e.g. columns in spreadsheets, buttons on websites)
- In the event of unstructured data (e.g., photos, PDFs), the screen scraper will use OCR to process the information into machine-readable text prior to transferring it to the chosen application.
Where may companies use screen scraping?
In the corporate world, screen scraping has two primary applications:
- RPA – App to App
RPA is one of the most advanced techniques in digital transformation because it allows for the automated processes of a variety of UI-dependent practices, such as daily P&L preparatory work in financial services, trying to update inventory records in the distribution chain, and going to enter patient information into health records (EHR) in health coverage. App to App screen scraping can occur.
- RPA – Web Scraping
To recognize HTTP components and transmit data into the desired format, web scrapers use screen scraping immediately.
