Dialog-type interface apparatus and method for controlling the same

A method of controlling a dialog type interface apparatus which provides contents corresponding to a voice signal received from a display apparatus, the method comprising:

• receiving a voice signal corresponding to a user's voice collected from the display apparatus;
• determining the user's utterance intentions based on the received voice signal, and generating a query for searching contents corresponding to the determined utterance intentions;
• and
• transmitting the generated query to an external server which divides and stores metadata on the contents per at least one item of an item table,
• wherein the generating extracts an utterance element for determining the utterance intentions in the voice signal, and converts the extracted utterance element to correspond to contents dividing criteria in the at least one item of the item table to generate the query.
