Interactive system, server and control method thereof

An interactive system comprising:

• a first server;
• and
• a display apparatus configured to receive a voice of a user, convert the voice to voice data and transmit the voice data to the first server,
• wherein the first server is configured to:
• parse a plurality of voice data received from a plurality of users,
• identify an utterance pattern based on the parsed plurality of voice data and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine,
• obtain query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern,
• store the obtained query data, and
• based on the voice data being received from the display apparatus of the user, perform, by the first server, a search related to the voice of the user by comparing the voice data with the stored query data.

A method for controlling a server, the method comprising:

• parsing, by the server, a plurality of voice data received from a plurality of users;
• identifying, by the server, an utterance pattern based on the parsed plurality of voice data and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine;
• obtaining, by the server, query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern;
• storing, by the server, the obtained query data;
• based on a voice data being received from a display apparatus of a user, performing, a search related to a voice of the user by comparing the voice data with the stored query data,
• in response to receiving data which corresponds to the voice of the user, determining whether the data is consistent with the stored query data;
• in response to the data being consistent with the stored query data, performing a search with the stored query data;
• and
• in response to the data being inconsistent with the stored query data, performing natural language processing with the data and performing the search according to a result of the natural language processing.

A server comprising:

• a storage;
• a communicator;
• and
• a controller configured to:
• parse a plurality of voice data received from a plurality of users,
• identify an utterance pattern based on the parsed plurality of voice data and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine,
• obtain query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern,
• store the obtained query data,
• based on a voice data being received from a display apparatus of a user, perform a search related to a voice of the user by comparing the voice data with the stored query data,
• in response to receiving data which corresponds to the voice of the user through the communicator, determine whether the received data is consistent with the stored query data,
• perform a first search with the stored query data in response to the data being consistent with the stored query data, and
• perform natural language processing and perform a second search according to a result of the natural language processing in response to the data being inconsistent with the stored query data.
