Parsers What is it and where are they used?

It is impossible to manually process significant amounts of data on the Internet. In this case, they use specially developed software – the parser. These programs are created for various tasks, primarily related to marketing and website promotion. AVADA MEDIA company offers both turnkey solutions in this area, as well as custom parsers.

Parsers

What is parsing and how does it work? Parsers

Parser is a program that provides parsing, that is, parsing content on the network using a specific mathematical model created in one of the programming languages, usually Python, PHP or Java. The algorithm of the parser program in each case is approximately the same:

  • the program gains access to the resource on the Internet;
  • loading the code of the page whose parsing is necessary;
  • reading and processing information;
  • providing the result in one of the convenient formats – .html, .xml, .sql and others.

The program compares a given set of words or meanings with those found on the network – taking into account the given limitations. The algorithm for further actions with the found content is also prescribed in advance – it can be just providing information or certain actions, for example, making bets when parsing sports events.

In fact, more than one resource or site page is usually parsed. So the process could be delayed for a very considerable time if the algorithm was executed sequentially for each new page. At the same time, the resources of the computer on which the parser works would be used only to a small extent. The solution to the problem is a multi-threaded parser that can process a huge number of pages and use the resources of your computer in the most rational way. Thus, parsing time is reduced by tens of times. The multi-threaded parser from AVADA MEDIA installed on a local computer or server is a solution that is more suitable for large companies.

Another solution from AVADA MEDIA is a cloud parser as a SaaS application. That is, the program is not installed on the client’s computer, but is located on the server, the resources of which are used during parsing. The client pays only subscriber access to the parser and uses it as necessary, without wasting resources of his computer. An online subscription parser is an excellent solution for small businesses in the field of advertising and marketing.

But why and to whom does it even need? Parsers

The most famous example of using parsers is search engines. They also use parsing programs to search for plagiarism and analysis of semantics in texts, without which no copywriter and SEO specialist can do. Therefore, the main area of ​​use is Internet marketing and search engine promotion. Using the parser, the semantic core of the site is compiled, and sites of competitors are analyzed.

I really need a parser for online store owners. With its help, they receive descriptions of goods, setting the model. Otherwise, it would have to be done manually each time, which would take hundreds of hours. AVADA MEDIA offers solutions for online trading – it can be either a cloud parser or downloadable software.

A separate area of ​​application is the parsing of exchange rates and cryptocurrency rates. For those who trade on the Forex exchange, it is important to receive up-to-date information on changes in rates on time. A special program will help – the exchange parser bot.

This program not only collects up-to-date information, but also trades on the exchange within the framework of user-defined variables – the exchange commission, the desired profit.

Bots are also actively used in the field of betting on sporting events, including cyber discipline. In this case, the parser program collects odds in various bookmakers. The user sets the search area – for example, certain disciplines, competitions or dates. The bot searches for odds and independently makes bets in user-defined examples. You can do this manually, but it takes much longer. In addition, the bot works around the clock, so you can bet on real-time events taking place in other time zones.

AVADA MEDIA company develops turnkey solutions for the field of online betting and currency trading, taking into account your requirements for the program. Our experts also develop parsers for specific narrow tasks for your business.
