The Advantages & Disadvantages of Web Scraping Data
Knowledge is power. Data is liberating.” To achieve access to the perfect items of knowledge, you’re first going to need to collect some data. Web scraping, data mining and web crawling are efficient strategies that let you easily compile and store information from websites on the internet.
In this piece we will examine what’s web scraping, the benefits and disadvantages of web scraping and some of the helpful use cases for scraping data.
What’s web scraping?
Web scraping refers to creating or utilizing a pc software to extract data from whole websites or just a few web pages. Additionally whenever you carry out web scraping, you’ll be able to either download all the web page or key features such as the
tag or article body content for further analysis.</p>
<p>What are the benefits of web scraping for business?</p>
<p>Achieve Automation</p>
<p>Strong web scrapers let you automatically extract data from websites, this allows you or your co-workers to avoid wasting time that will’ve have otherwise been spent on mundane data assortment tasks. It additionally means that you can collect data at greater volume than a single human may ever hope to achieve.</p>
<p>Additionally it’s potential so that you can create sophisticated web bots to automate online activities with either web scraping software or using a programming language comparable to javascript, python, go or php.</p>
<p>Enterprise Intelligence & Insights</p>
<p>Web scraping data from the internet lets you seek for competitor prices, monitor their marketing activity and to swiftly market research your industry online. By downloading, cleaning and analysing data at significant quantity, you’ll be able to build a greater picture of your market, your competitor’s activity which in flip will lead to higher business resolution making.</p>
<p>Unique and rich datasets</p>
<p>The internet provides you with a rich amount of text, image, video and numerical data and at present accommodates not less than 6.05 billion pages. Relying upon what your goal is, you can find related websites, setup website crawlers and then make your own custom dataset for analysis.</p>
<p>For example, let’s pretend you’re involved in UK football and want to understand the sports market in depth.</p>
<p>You may setup webscapers to collect the following data:</p>
<p>Video Content: To download all the football games from YouTube or Facebook.com.</p>
<p>Football Statistics: You could download your desired crew’s historical match statistics.</p>
<p>WhoScored – Goal Data.</p>
<p>SoccerStats.</p>
<p>Betting Odds: You possibly can accumulate the betting odds for football matches from bookmaker’s corresponding to Bet365 or from player betting exchanges reminiscent of Betfair or Smarkets.</p>
<p>Create applications for tools that don’t have a public developer API</p>
<p>By web scraping data, you will by no means have to rely on the website releasing a public application programming interface (API) to access the data which they show on their webpages. There are several benefits to web scraping compared to accessing a public API:</p>
<p>You can access and gather any data that’s available on their website.</p>
<p>You are not limited to a selected number of queries.</p>
<p>You don’t need to sign up for an API key or have to abide by their rules.</p>
<p>Efficient Data Management</p>
<p>Instead of copying and pasting data from the internet, you can select what data you’ll like to collect from a range of websites, then you’ll be able to accurately accumulate it with web scraping. For more advanced web scraping / crawling techniques your data will be stored within a cloud database, and will likely be running on a each day basis.</p>
<p>Storing data with automated software and programs implies that your organization, operations or workers can spend less time copying and pasting info and more time on creative work.</p>
<p>What are the disadvantages?</p>
<p>You will have to learn programming, use web scraping software or to pay a developer</p>
<p>If you’re looking to collect and organise an enormous amount of knowledge from the internet, you will discover that existing web scraping software is limited in functionality. Although the software will be good for extracting several components from a web web page, as quickly as you must crawl a number of websites they’re less effective.</p>
<p>Subsequently you will have to either spend money on learning web scraping strategies in a programming language reminiscent of javascript, python, ruby, go or php. Alternatively you possibly can hire a freelance web scraping developer, regardless each of those two approaches will add an overhead to your data collection operations.</p>
<p>Websites usually change their construction and crawlers require maintenance</p>
<p>As websites often change their HTML construction, sometimes your crawlers will break. Whether you’re using web scraping software or you’re writing the web scraping code, there’s a certain quantity of upkeep that needs to be commonly carried out to keep your data assortment pipelines clean and operational.</p>
<p>For every website that you write a custom encoding script, adds on a certain amount of technical debt. If lots of websites that you just’re collecting data from all of a sudden resolve to redesign their websites, you will must put money into fixing your crawlers.</p>
