The key advantage of extracting data from websites is the ability to gather large amounts of information quickly and efficiently. This can be particularly useful for blogers, researchers or businesses needing to collect data for analysis or decision-making purposes. However, the process is not without its problems. Firstly, websites may use anti-scraping mechanisms such as CAPTCHAs or IP blocking systems that impede data extraction efforts. Additionally, legal issues may arise if the terms of service of a website explicitly prohibit scraping activities. The quality and reliability of the extracted data might also be compromised due to inconsistencies in web page structures or changes made frequently by website owners. That’s why it’s important to approach the process of extracting content from websites responsibly and apply well-designed web scraping and natural language processing tools, such as the Python programming language and its libraries boilerpipe, nltk, pymorphy, httplib, BeautifulSoup. In today’s post, I

Parsing news websites serves the purpose of extracting valuable and relevant information from a vast sea of articles, ensuring that users can access the desired content efficiently. By dissecting web pages, parsing algorithms retrieve specific data such as article titles, authors, publication dates, and text summaries, providing comprehensive metadata. This process assists various professionals in staying updated with current events across multiple domains by automating the gathering of news articles from different sources into a consolidated format. Journalists rely on parsing to monitor competitors’ coverage and gather background information before composing their own stories. Additionally, researchers benefit greatly from automated parsing as it accelerates their data collection for studying trends or sentiment analysis. Moreover, financial institutions utilize parsers to extract key stock market insights quickly. Parsing news sites with BeautifulSoup is a highly effective method for professionals who need to extract and analyze specific information from online news articles. As

What if you need to get a lot of information from a certain site in a short time? In this situation, website scraping is the best solution. Web scraping can be used to search for prices and product details, compile market research, check competitors’ products and services, mine job postings and reviews, collect contact information, analyze competitor strategies, monitor news stories and more. When done professionally and ethically it is an invaluable tool that can save businesses time while other forms of data collection could become costly in both time and money. Through the use of Python’s scraping libraries such as BeautifulSoup, Selenium, and Requests, it is easy to build complex and customized programs for website scraping. This allows for quick gathering of structured or unstructured data from multiple sources in order to satisfy varied analytics requirements. In the link below I will show you how you can use Python

Many online stores focus on the assortment and prices of major online retailers, such as Amazon, Ebay, Aliexpress. Collecting this data manually is a tediously long and often pointless task. Because all the prices and assortments can change several times during the data collection process. That’s why usually all this data is just parsed. I was asked by a client to write a parser of products and their prices from Aliexpress.ru. Aliexpress is an online shopping experience that offers products from some of the world’s top brands and suppliers at competitive prices. It was founded in 2010, and has become one of China’s largest businesses. In addition to being a great place for consumers, Aliexpress also has a business side that allows wholesalers to browse through a range of products from more than 70 countries worldwide. With over 100 million active buyers and 8 million sellers, it’s not surprising that

Extracting information from websites is one of the most important skills in modern data science. Because it is the Internet today that is the key source of information for various studies. Parsing websites can be a tricky business, especially for those with limited technical knowledge. Trying to extract data from HTML and other web formats is no easy feat – you’ve got to figure out the structure of the site first and understand what bits need to be scooped up before you can actually do any parsing. And then there are things like javascript which can add additional layers of complexity. If you’re not careful, it’s easy to miss out on important information or accidentally parse in duplicate records. An additional difficulty in extracting information from websites is that all sites differ in structure, as well as in code and markup. And the bigger and older the website, the more
