Abstract: A method for indexing a suffix tree in a social network includes: scanning an input string and dividing the string into partitions each having a common prefix; performing no-merge suffix tree indexing on the divided partitions; storing information on the partitions on which no-merge suffix tree indexing is performed; storing suffix nodes of the no-merge suffix tree; and establishing a prefix tree. The performing no-merge suffix tree indexing includes: generating a set of suffixes having the common prefix in the input string; generating a suffix set from the set of suffixes and storing the suffix set; and building the suffix set as a sub-tree.

Abstract: Disclosed herein is an apparatus and method for providing social magazine information. The method is configured such that an apparatus operating in conjunction with at least one user terminal provides social magazine information to a corresponding user terminal. In the method, a social magazine is dynamically reconstructed according to a context of a user of each user terminal. Customized information corresponding to the user terminal is provided based on the reconstructed social magazine. A community is formed among user terminals which share the reconstructed social magazine, and social magazine information is shared through the formed community.

Abstract: A real-time audio/video communication method for use on the Internet in conjunction with a homepage and a device therefor are provided. According to the method of a real-time audio/video communication between each terminal using the Internet, the communication capability and the current status of a receiving party are registered in a homepage within a terminal or a web server connected by the receiver, and a sending party accesses the receiver's homepage within the web server to initiate communication. This method allows the receiver to receive realtime audio/video communication data at any time without being always connected to the Internet. Furthermore, in the real-time audio/video communication device, an Internet Service Provider provides a homepage so that the ISP may recognize the communication status of each terminal to access the sending and receiving terminals under optimum communication conditions, and decodes the optimum communication conditions.

Abstract: An inter-terminal communication protocol method in which a terminal determines whether the other terminal uses an identical predetermined protocol by sending a bit stream which does not violate a standard protocol before a negotiation of the standard protocol. If the terminals use the same predetermined protocol, the negotiation is omitted, necessary information ordinarily obtained from the negotiation is detected from a prepared information table, and then communication starts. If the other terminal does not use the identical predetermined protocol, the negotiation is initiated.
