摘要
提出了断接下移动终端简单查询算法SQPID,该算法通过合并与裁剪操作构建综合相关语义缓存项,且合并过程不涉及间接相关性判断,从而简化了以往算法的处理过程,提高了近似查询结果的导出速度。实验表明,SQPID算法在查询响应时间和精确度方面都更好地满足了用户的需求。
A simple query processing algorithm SQPID (simple query processing in disconnection), was proposed. Main idea of SQPID is to build integrated related semantic cache item about current query through combining and clipping op-erations. In order to simplify the procedure, SQPID’s combine does not involve indirect relativity estimation. The results of simulated experiments show that SQPID’s query response time and degree of accuracy better meet client’s require-ments than QPID algorithm.
