This observation also inspires the development of our cost model, which can evaluate the best number of merged lists. Experimental results show that ListMerge could outperform the baseline algorithms up?to 4–20 times in synthetic datasets generated by various distributions.

Mei Zhang,Aijun Zhang,Yongdao Zhouir semantic meanings. To achieve that, we propose a novel indexing structure called NIQ-tree, which integrates spatial, textual and semantic information in a hierarchical manner, so as to prune the search space effectively in query processing. Extensive experiments are carried out to evaluate and compare it with other two baseline algorithms.

Experimental results show that our proposal is both effective and efficient to handle streaming trajectories without compromising the quality.

Our comprehensive experimental study on synthetic and real datasets demonstrates the proposed approach is the most efficient algorithm for R.NN.
