| Abstract(in English) | In a microblogging service like Twitter, many short messages are posted each day. Some of them represent replies or messages forward among users. Creating a diffusion network to represent such forwarded messages is important to understand who forwarded the message and to identify the most influential users in the diffusion network. It is important to do this information diffusion analysis at a rapidly because social media data quickly loses its value. We are working on an information diffusion analysis system. To access the data more quickly, we developed a matrix index containing some of the data needed for diffusion analysis in a data access layer within an application server. This is a large and sparse matrix, so we use data compression techniques. We are currently studying the performance and overhead when encoding and decoding the matrix. |
