KT0401: Concept and Definition
Data scraping refers to the automated process of extracting information from websites, databases, or digital platforms.
Web scraping is commonly used to collect large amounts of information quickly and efficiently.
Instead of manually copying information from websites, automated tools and scripts gather data automatically.
Data scraping may involve extracting:
-
Product information
-
Prices
-
Customer reviews
-
Market trends
-
Financial data
-
Contact information
-
News articles
Data scraping is important because organisations rely on data to support:
-
Business analysis
-
Automation
-
Reporting
-
Research
-
Decision-making
In RPA environments, bots often perform scraping activities automatically as part of larger automation workflows.
KT0402: Purpose of Data Scraping
The purpose of data scraping is to collect useful information efficiently from online or digital sources.
Organisations use data scraping to:
-
Gather market information
-
Monitor competitors
-
Analyse customer behaviour
-
Generate reports
-
Collect research data
-
Support automation processes
Examples of data scraping applications include:
| Industry | Example |
|---|---|
| Retail | Monitoring product prices |
| Finance | Collecting stock market data |
| Marketing | Gathering customer trends |
| Recruitment | Collecting job listings |
| Research | Gathering online information |
Data scraping improves productivity because large amounts of information can be collected automatically and processed quickly.
KT0403: Data Scraping Tools
Data scraping tools are software applications or frameworks used to collect and process information from websites and systems.
Common data scraping tools include:
-
Beautiful Soup
-
Scrapy
-
Selenium
-
UiPath scraping tools
-
Octoparse
-
ParseHub
Features of Data Scraping Tools
These tools may provide:
-
Automated data extraction
-
Web navigation
-
Data storage
-
Browser automation
-
Data filtering
-
Integration with databases
In RPA environments, scraping tools are often integrated into automation workflows to process information automatically.
KT0404: Legal Issues
Although data scraping is widely used, organisations must ensure that data collection activities comply with legal and ethical requirements.
Common legal considerations include:
-
Privacy regulations
-
Copyright laws
-
Website terms and conditions
-
Data protection laws
-
Intellectual property rights
Improper scraping activities may result in:
-
Legal penalties
-
Security violations
-
Privacy breaches
-
System blocking
Organisations must ensure that:
-
Sensitive information is protected
-
Data is collected ethically
-
Scraping activities comply with regulations
-
User privacy is respected
Responsible data scraping practices are important in automation and digital business environments.
KT0405: Web Scraping Procedure
Web scraping follows a structured process to collect and organise information.
Step 1: Find the URL to Scrape
The first step is identifying the webpage or online source containing the required information.
Step 2: Inspect the Page
Developers inspect the webpage structure to identify where the required data is located.
This may include:
-
HTML elements
-
Tags
-
Classes
-
IDs
Step 3: Find the Data to Extract
Specific information is identified for extraction.
Examples include:
-
Product names
-
Prices
-
Contact details
-
Tables
-
Images
Step 4: Write the Code
Developers create scripts or automation workflows to extract the required information.
Example scraping technologies may include:
-
Python scripts
-
RPA bots
-
Scraping frameworks
Step 5: Run the Code and Extract the Data
The script or automation tool retrieves the information automatically.
Step 6: Store the Data in the Required Format
Extracted information is stored in formats such as:
-
CSV files
-
Databases
-
Excel spreadsheets
-
JSON files
Proper storage allows organisations to analyse and use the information effectively.
KT0406: Libraries Used for Web Scraping
Libraries are collections of prewritten code used to simplify development tasks.
Web scraping libraries help developers extract and process information efficiently.
Common web scraping libraries include:
| Library | Purpose |
|---|---|
| Beautiful Soup | Parses HTML and XML |
| Scrapy | Web scraping framework |
| Selenium | Browser automation |
| Requests | Sends HTTP requests |
Beautiful Soup
Beautiful Soup helps developers navigate and extract information from HTML pages.
Scrapy
Scrapy is a powerful framework designed for large-scale scraping projects.
Selenium
Selenium automates browser interactions and is useful for dynamic websites.
Requests Library
The Requests library sends HTTP requests to websites to retrieve webpage information.
Libraries improve efficiency because developers do not need to write all scraping functionality from scratch.
Data Scraping in Automation and RPA
In automation environments, RPA bots may use scraping technologies to:
-
Extract website information
-
Process customer data
-
Collect reports
-
Monitor systems
-
Automate repetitive online tasks
Data scraping supports intelligent automation because bots can collect information automatically and feed it into workflows and reporting systems.
