Cache Strategies for Semantic Prefetching Data
Sang-Won Kang, Jongwan Kim, Seokjin Im, HaRim Jung, Chong‐Sun Hwang · 2006
In this paper, we propose a Semantic Prefetching (SP) scheme as a new dissemination method for semantic information, using a dynamic caching strategy that considers a preference of user in Semantic Prefetching Area (SPA). Our contribution is that a proposed mechanism maintains query results in the cache before a user requests a query. In SP, an efficient algorithm for searching a prefetching description Fd is introduced with definitions, and we propose a new query processing algorithm with a Preference Priority Replacement (PPR) strategy to manage cache. Through an extensive performance analysis, we show that SP is superior to existing caching mechanisms for location-based services.
