This study examined the global structure of intercultural communication on a computer-mediated communication network. Extracted from a total of 232,479 discussion messages, a matrix of crossposted messages among 133 online newsgroups over a year on the Usenet was analyzed to investigate structural patterns of communication flow. This research found, unlike earlier research, that a simple structure of core-periphery relations does not fit the pattern of cross-cultural postings in Usenet discussion groups. Bonacich's centrality, cluster analysis, and multidimensional scaling analysis were conducted using UCINET V software. Results identified a multi-cored structure with decentralized and diversified patterns of information distribution in cyberspace.
