| Abstract(in English) | Recently, the improved transmission speed and mobile device capability in wireless access networks enable us to use rich content in mobile environment. Demand prediction is important technique for content services. However, it is hard to predict local demand in mobile environments because it depends not only on just user preference and the popularity of common content but also on other factors. Thus, we need to consider the context with multiple factors affecting the demand. In addition, we also need to consider the sequence of contexts. We call a sequence of contexts social context. In this paper, we propose a novel demand prediction engine that extracts local demand depending on social context and estimates what content will be requested there. To extract the demand, we use a log database and a pattern-matching technique in our prediction engine. To validate our prediction engine, we apply a prefetching service using the engine to a mobile content service. |
