Also, there are techniques which have worked very well in performance optimization for relational databases. Yet these techniques are in the process of integration into big data analytics. Indexing and its data structure is an example of such techniques. Despite its popularity in query optimization ...
We propose TEDI, an indexing for solving shortest path, and k Nearest Neighbors (kNN) problems. TEDI is based on the tree decomposition methodology. The graph is first decomposed into a tree in which the node contains vertices. The shortest paths are stored in such nodes. These local shortest...
R-Tree Based Indexing of General 来自 ResearchGate 喜欢 0 阅读量: 15 作者: Authors Simonas Saltenis,CS Jensen,Christian S. Jensen codirector,MH Bohlen,Bongki Moon 摘要: Real-world objects are inherently spatially and temporally referenced, and many database applications rely on databases that ...
This paper addresses such problems and presents a novel indexing technique, Feature Based Adaptive Tolerance Tree (FATT), which is designed to bring an effective solution especially for indexing large databases. The proposed indexing scheme is then used along with a query by image content, in ...

In LBMVBT, to reduce the number of writes to PCM in maintaining the index and improve the efficiency in serving version-range queries, we introduce the block-based scheme for indexing in which multiple versions of a data item are grouped into a version block to be indexed by a single ...
There is a growing need for the ability to query image databases based on similarity of image content rather than strict keyword search. As distance computations can be expensive, there is a need for indexing systems and algorithms that ... Andrew,P,Berman,... - 《Computer Vision & Image ...
