Abstract. The development of index structures that allow ecient retrieval of spatial objects has been a topic of interest in the last decades. Most of these structures have been d...
Index structures for multiple sets can be classified into those that group entries according to their key values and those that group entries according to their set membership. Th...
A path dictionary encodes the connections among objects in the aggregation hierarchy. It has been shown to be an efficient mechanism for supporting nested object queries [6]. In t...
We develop a new algorithm for clustering search results. Differently from many other clustering systems that have been recently proposed as a post-processing step for Web search ...
Multi-dimensional index structures such as R-trees enable fast searching in high-dimensional spaces. They differ from uni-dimensional structures in the following aspects: (1) inde...
