Electronic device and control method thereof

An electronic device, comprising:

• a communication interface;
• a memory;
• and
• a processor configured to:
• store metadata received from a plurality of data sources, respectively, in the memory,
• transmit, through the communication interface, first metadata and second metadata to an external search engine,
• obtain, through the communication interface, the first metadata and the second metadata filtered from the external search engine, wherein the first metadata and the second metadata are filtered based on a similarity between pieces of information corresponding to a preset attribute from among a plurality of attribute information,
• obtain first information corresponding to the preset attribute from among a plurality of attribute information comprised in the first metadata filtered from the external search engine,
• obtain second information corresponding to the preset attribute from among a plurality of attribute information comprised in the second metadata filtered from the external search engine, and
• map, based on the first metadata and the second metadata being identified as metadata on a same content based on a similarity between the first information and the second information, an integrated metadata generated based on the filtered first metadata and the filtered second metadata to the same content and store the mapped integrated metadata generated based on the filtered first metadata and the filtered second metadata in the memory.
