SocRent

In March 2017, I launched a service for parsing and classifying apartment rental ads from vk.com.
You can read more here about how I experimented with different methods to classify ads and ultimately chose the Yandex Tomita Parser as a lexical parser.
Developing the first version of the service took about a year.

Architecture

• rent-view - the service renders HTML pages and serves it
• rent-collector - the service collects ads, classifies them, and saves them to the database
• rent-parser - the service extracts structured data from text using Tomita parser
• rent-control - admin panel
• rent-notifier - notification service

You can also read here about the project's architecture and the technologies.

Technologies

• PHP
• NodeJS
• Golang
• MongoDB
• Beanstalk Queue
