Method of image searching based on artificial intelligence and apparatus for performing the same

An apparatus for image searching based on artificial intelligence (AI), the apparatus comprising:

• a data collection unit configured to acquire retrieved information including at least one of a retrieved image and an image address and a user query on the basis of a search result of an image search engine;
• a query keyword detection unit configured to detect a keyword-category combination on the basis of a type of the acquired user query;
• a cache data matching unit configured to determine whether cache data that matches the detected keyword-category combination exists;
• an image object detection unit configured to generate, in response to absence of the cache data that matches the keyword-category combination, an object-category combination through an AI technology-based object detection on the acquired retrieved information;
• and
• an element matching and storage unit configured to, when the acquired keyword-category combination and the object-category combination match each other in units of combination elements as a result of combination element matching performed between the acquired keyword-category combination and the object-category combination, display the retrieved image from which the object-category combination is detected, and map and store the keyword-category combination and the image address of the retrieved image as new cache data.
