Andrzej Więckowski,Alicja Sznurawarantee completeness and validity of the map. The common problems of them involve huge computation and low precision. More importantly, they scarcely consider inferring new roads on sparse unmatched trajectories. In this paper, we first address the issue of finding new roads in sparse trajectory area

Andrzej Więckowski,Alicja Sznurawahe skycube computation is proposed to compute skylines, or cuboids, on all possible non-empty dimension subsets. The key issue of computing skycube is how to share computation among multiple related cuboids, which classified into . and .. However, state-of-the-art algorithm only leverages . to compu

The Academy of International Businesse result number and result quality, we combine query result diversity with query relaxation. Relaxation guarantees the number of the query results, returning more relevant elements to the query if the results are too few, while the diversity tries to reduce the similarity among the returned results.

Kevin Ibeh,Oliver Borchert,Colin Wheeler CQA sites often varies a lot from precise and useful ones to irrelevant and useless ones. Hence, automatic detection of low-quality answers will help the site managers efficiently organize the accumulated knowledge and provide high-quality contents to users. In this paper, we propose a novel unsupe

OLAP is also applicable to data streams, however the requirement to produce real time analysis on fast and evolving data streams is not possible unless the data to be analysed reside on memory. Keeping in view the limited
