Electronic device, contents searching system and searching method thereof

An electronic device comprising:

• an input interface comprising circuitry configured to receive a query for searching;
• an output interface comprising output circuitry;
• and
• a processor,
• wherein the processor is configured to:
• create a keyword vector by extracting a keyword from the provided query,
• obtain a searching contents candidate group based on a first similarity between contents indexing data created by a preset natural language processing-based search model and the created keyword vector,
• obtain a second similarity between the created keyword vector and vector data included in the searching contents candidate group based on a trained artificial intelligence model,
• align contents included in the searching contents candidate group based on the obtained first similarity and the second similarity, and
• control the output interface to provide the aligned contents.

A contents searching system comprising a terminal device and a server, comprising:

• a terminal device comprising circuitry configured to:
• receive a query for searching and transmit the query to the server;
• and
• a server configured to receive the query for searching from the terminal device,
• wherein the server is further configured to:
• create a keyword vector by extracting a keyword from the provided query,
• obtain a searching contents candidate group based on a first similarity between contents indexing data created by a preset natural language processing-based search model and the created keyword vector,
• obtain a second similarity between the created keyword vector and vector data included in the searching contents candidate group based on a trained artificial intelligence model,
• align contents included in the searching contents candidate group based on the obtained first similarity and the second similarity, and
• transmit the aligned contents to the terminal device, and
• wherein the terminal device is further configured to output the aligned contents received from the server.
