System for online-discussion service and method thereof

An on-line discussion service system and method are provided to allow a plurality of users to perform an in-depth discussion through an on-line network and give a reward to a user according to a voting result such that users actively participate in the discussion. An on-line discussion service system(130) includes a user information storage unit(131), an authentication unit(132), a discussion room opening unit(133), an audience admission unit(134), a panel selecting unit(135), a discussion unit(136) and a discussion content storage unit(137). The authentication unit authenticates users. The discussion room opening unit transmits information on discussion data previously stored in the discussion content unit to an authenticated user at the request of the user and opens a discussion room about the theme of a discussion selected from the discussion data. The audience admission unit receives admission request signals from audiences and admits the audiences into the discussion room. The panel selecting unit designates at least two panels. The discussion unit provides the discussion data previously stored in the discussion content storage unit and allows the user who requests the discussion room to be opened and the panels to give and receive information on the theme of the discussion in real time through a predetermined medium according to a predetermined policy. The discussion content storage unit stores the contents of the discussion between the user and the panels.
