Abstract: Disclosed are an apparatus and method for providing a community service. The apparatus includes a content analysis unit configured to generate a plurality of content figures representing a plurality of pieces of content, and generate connection relationships of the plurality of content figures according to connection relationships among the plurality of pieces of content, a content management unit configured to set a size value of an upper content figure based on lower content figures, from among the plurality of content figures, connected to lower hierarchies of the upper content figure, and a content transmitter configured to transmit connection relationships of the plurality of content figures and size data that includes the size value to a user terminal connecting to an on-line community. Accordingly, an overall trend may be noticed at a glance, and it may be possible to prevent content spamming because meaningless content would fall behind.

Abstract: Exemplary embodiments of the invention provide an apparatus for providing a mind map-type online community service, capable of maintaining the “theme-wise” direction of conversations by forming nodes in a shape with a protrusion in response to content being created by a user.
