Abstract: Provided is a method of searching for an app name in a user terminal. The user terminal requests a download of an app from an app storage server. The user terminal transmits a language set in the user terminal and an app name of the app to an app name processing server. The app name processing server acquires a word in the set language corresponding to the app name through a machine learning technique, and stores the acquired word in an app search database (DB) connected in the user terminal.

Abstract: Provided is a method of classifying, into an album, one or more image files stored in a terminal with a screen to which a touch screen is applied. Album/folder information included in the terminal is confirmed. An image file stored in the terminal is displayed on the screen of the terminal. It is determined whether a predetermined specific gesture is input with respect to the image file. When the specific gesture is input, it is determined whether the album/folder information is stored. When it is determined that the album/folder information is not stored, album/folder information is recommended. Both or one of the recommended album/folder information and the stored album/folder information is displayed on the screen of the terminal. It is determined to which album/folder information a drag is made among the album/folder information displayed on the screen of the terminal. The image file is moved to an album/folder corresponding to the album/folder information to which the drag has been made.

Abstract: Provided is a country-specific telephone number system analysis system. The system includes a telephone number system analysis logic server; a number analysis machine learning system; a country-specific international call service provider information database; a country-specific telephone number system information database; and a telephone call connection logic database. The telephone number system analysis logic server receives a target telephone number of a telephone call from a user terminal, and checks whether the target telephone number conforms to an international telephone number system protocol. When it is determined that the target telephone number does not conform to the international telephone number system protocol, the number analysis machine learning system identifies a country corresponding to the target telephone number by accessing the country-specific telephone number system information database.
