Hyundai brand has been going through a difficult time recently. A series of failures, breakdowns and problems with Hyundai Rotem high-speed trains connecting Ukrainian cities has triggered a wave of criticism and well-grounded discontent from both passengers, and all other citizens.

In such critical situations negative attitude to a product is sometimes extended to the entire brand. Therefore we wanted to test a hypothesis and check if negative attitude towards Hyundai cars increased due to a rise in popular indignation related to Hyundai Rotem trains.

If you have ever worked in our system, you could notice that a right side of the SemanticForce dashboard had a plethora of filters: geography, author, source etc.

Today we are discussing a geographic filter: how it works, what it can do, and how you can use it.

Geographic identification offered by SemanticForce makes use of different principles for various types of media:

• a permanently updated vocabulary of web sites for mass media and regional forums;
• a profile vocabulary for social webs and blogs (for instance, the systems stores over 10 different spellings for the city of Saint Petersburg, which can be used by its inhabitants in their personal profiles);
• geographic data in Twitter.
