The Machinio database is formed automatically. Web crawlers go through sellers' websites and listings to collect the necessary data. The seller only signs a contract with the platform and pays for the subscription.
The corporate crawler has some limitations, Ferrum is used as an additional tool . This is an open-source web driver created with the participation of Evrone. With its help, it is possible to collect data from sites on React or Vue.
Ferrum and one crawler are enough to gambling database russia parse the necessary information. Although each seller's site has its own structure and design, the sites often have similar markup. That's why we wrote just one crawler and adapted it for different listings.
Data collection and processing takes place in two stages:
The crawler saves the data in the form presented on the site.
The seller does not always fill out the catalog completely, sometimes errors occur - for example, the photos do not match the declared model. Therefore, the second stage is validation, which also occurs automatically.
How does data collection work?
