During the covid19 pandemic, unfortunately, the tourist industry has suffered greatly. As you know most people including myself have had to work remotely, and like most, I have been uneasy about going traveling or going shopping. So, I started to thinking how AI and Tech could help people to boost the tourist economy during and after the pandemic. One of the scenarios in the tourist industry is that when people shop around, they will start to compare and find the best price vs quality for the products they want. But now with the covid19 virus, it is a little risky to shop around and compare the same products with different offers. The Cognitive AI Search Engine will provide an open-source framework that can enable traditional shops and web services AI Search functionality. For example, when a tourist finds a souvenir and he/she wants to compare it, it isn’t always so simple. Maybe they feel uncomfortable directly asking or (or maybe they cannot speak the local language), with this software they can take pictures with a cellphone, and query the top 10 similar pictures using this Cognitive AI Search Engine.
