Abstract: An electronic device may include a wireless communication circuit, a memory, and a processor. The memory may store instructions that allow, when executed, the processor to: obtain context information associated with the state of the electronic device, and contents information being provided by the electronic device; extracting first keywords on the basis of the context information and the contents information; analyze the keyword level for the first keywords; changing the first keywords into a superordinate concept according to preset keyword levels to obtain second keywords; and transmit the second keywords to at least one server by using the wireless communication circuit. Other various embodiments identified through the specification are possible.

Abstract: An electronic device includes a memory configured to store a plurality of types of user data, and a processor configured to be operatively connected to the memory, wherein the processor is configured to generate an embedding vector through text embedding using first text data which is included in the user data and is related to content of the user data for each type of the user data; calculate a weight for the embedding vector using information which is included in the user data and is related to usability of the user data for each type of the user data; when a query is input, generate a query vector through the text embedding using second text data included in the query; and quantify user interest in the query for each type of the user data based on the embedding vector, the weight for the embedding vector, and the query vector.

Abstract: An electronic device that includes a communication module and a processor operatively connected to the communication module to exchange data with an external electronic device through the communication module is provided. The processor generates user data and a user profile based on collected user information related to a plurality of items, receive learning information data related to the plurality of items from the external electronic device, generate user learning data by applying the learning information data to the user data, learn a user preference pattern based on the user learning data, update the user profile based on the learned user preference pattern, and receive recommended item data from the external electronic device based on the updated user profile.
