Prefetching-Based Mobile Dictionary

A network-based mobile dictionary requires frequent accesses from a mobile device to a dictionary server for searching or downloading materials. In this paper, we propose a prefetching-based mobile dictionary to reduce the network communication cost. We first propose an overall working framework for the prefetching-based mobile dictionary. We then present a method of determining the amount of prefetching data for each of packet-based and flat-rate billing types. We also propose a method of determining the words to be fetched in the near future. Through experiments, we finally show superiority of our prefetching-based method.
