Blogs have emerged as a powerful, to convey and spread any, sort of ideas. Thousands of people write daily in these on-line diaries and hold a captive audience. Furthermore information spread in blogs provide an online laboratory to analyze how brands, trends, ideas and information spread through social communities in the Internet. To support this analysis, in this paper describes an ontology for Blogs (BloOn) which describes the blog data domain and enable services for analyzing and reasoning over blog data across applications; and proposes a blog ontology visualization system (BloViS) based on 3D visualization techniques, metaphors and the incorporation of virtual world features for the users to investigate the nature of meme dissemination. We expect that this proposed Information Visualization platform may advance the state of the art of Internet memetics phenomena, blog ontology, and 3D visualization of digital memes.
