Methodology of data collection
The amount of data we have in our life is continually expanding. Our lives are becoming increasingly data-rich. Despite the fact that data originates from a variety of places, the internet is the most important storehouse. As big data analytics, artificial intelligence, and machine learning develop, businesses will need data analysts who can scrape the web in increasingly complex ways.

Web scraping is a technique for collecting data and content from the internet (also known as data scraping). Most of the time, this data is saved in a local file that may be changed and reviewed as needed. Scraping websites is similar to copying and pasting information from a website into an Excel spreadsheet but on a much smaller scale.

When people talk about “web scrapers,” they’re usually referring to computer programs. Web scraping software (sometimes known as “bots”) is software that visits websites, captures relevant pages, and extracts useful data. These bots can retrieve massive amounts of data in a short amount of time by automating this process. In the digital age, the utilization of big data, which is continually updated and changing, has clear advantages.
Web scrapers operate in a complicated manner. Its goal is to decipher a website’s structure in order to extract the data needed and export it in a different format. Web scrapers are often given a specific URL to scrape data from a website (or a collection of URLs). The scraper will either extract all of the data on the page, or you can select the data you want to collect, depending on your preferences. Finally, the scraper will run, and the user will be able to download the information in Excel or another format.
Analyzing and structuring data
After obtaining the desired data, it should be cleaned and ordered. Typical datasets include:
- Duplication of data
- Data points that are incomplete
- Corrupted data
- Data formatted incorrectly
- Mislabeled information
The latter is fairly common in the music industry, for example. Thus, as a result of incorrect labelling, metadata such as ‘artist name’ or ‘record company’ may be miscatalogued, resulting in the loss of large amounts of money.
Working with clean datasets is critical for getting the most out of your company’s data. AI and machine learning algorithms, for example, are taught by being fed data throughout the operational or maturity phase, allowing them to identify and evaluate patterns. The output, insights, and business choices will all be skewed if the data provided to algorithms during the training phase is skewed in some way (e.g., a significant time lag or location mistakes). Because the approach varies depending on the target dataset, there is no such thing as a “one-size-fits-all” data cleaning methodology. The following are a few techniques for data cleansing that could be employed.
Correction of naming inconsistencies: Dataset classification must occur in some form, and this is where naming conventions come into play. This is exemplified by a SaaS platform that attempts to identify competitors’ prices in order to inform its dynamic pricing strategy. These companies may collect data from competing websites that sell monthly plans as Price per month, PPM, $600/m, and other variations of the same monthly price scheme under other labels. If these faults are not rectified, the products will be categorized differently, and your comparative pricing will be wrong.
Getting rid of redundant or irrelevant information: Data is regularly acquired and cross-referenced from a variety of sources, including various social media platforms, for the same subject matter. This enables your team to organize related data, such as vendor information. Irrelevant data, for example, could comprise social media updates that show on an account but have no bearing on your product. To improve the efficacy of algorithms that consume this data, this material must be searched for (either manually or automatically) and deleted.
Data organization for unstructured data
Unstructured data makes up the vast majority of web data collected on the internet. In unstructured data, there are no labels, fields, annotations, or attributes to help robots recognize data components and their relationships. Unstructured data usually has a lot of text or is in HTML format, which is simple for people but challenging for machines to grasp. Data will very certainly need to be prepared in order to be relevant to your firm. Unstructured data can be organized in a variety of ways; here are a few:
- Identify patterns of interpretation by utilizing tools such as Natural Language Processing (NLP) and text analytics.
- Text structuring using tag-based or manual tagging of metadata or sections of speech.
Obtaining data automatically
The data scraping tool from Proxycrawl completely automates the data collection process, presenting data and methods in forms that team members may use right away, such as JSON, CSV, or Excel. You can also select your data delivery method, such as whether you want real-time data as it is gathered or a complete dataset once the collection procedure is over, as well as how you want the data supplied, such as by Webhook, Email, or the cloud.
Before distributing the unstructured data, the Data scraper cleans, matches, synthesizes, analyses, and structures it using an algorithmic method based on industry-specific expertise. It’s a solution that automates the entire process detailed above, allowing for real-time, zero-infrastructure data flow. It also employs retry logic and adapts and readjusts site blocks to ensure that you always have access to the open-source content you want.
Data collection is a time-consuming procedure that is part art and half science, no matter how you do it or what approach you use. Companies can also utilize Data Collector to provide team members and algorithms with ready-to-use datasets, allowing them to focus on strategy, innovation, and important business models.
