Interactive question-answering apparatus and method thereof

An interactive question answering method in a server including a computer processor communicating with a user terminal over a communication network, the interactive question answering method comprising:

• generating, by the computer processor, meta-information including identification information about a plurality of entities which are predicted to attract interest of a user in multimedia content and attribute information assigned to the identification information;
• transmitting, by the computer processor, the multimedia content and the meta-information to the user terminal;
• receiving, by the computer processor, a question sentence about an entity selected from among the plurality of entities by the user and identification information about the entity, selected by the user and extracted from the meta-information, from the user terminal;
• and
• generating, by the computer processor, an answer sentence to the question sentence, based on attribute information assigned to the identification information about the entity selected by the user and transmitting the answer sentence to the user terminal,
• wherein the identification information is constructed to have an attribute of multimodal information output from a multimodal interface included in the user terminal, the attribute of multimodal information being used as a hint information.
