Efficient Indexing for OLAP Query Processing with MapReduce
As in the conventional databases, an index can be used to improve performance in MapReduce when processing OLAP queries with it. Regarding this, Hadoop++ suggested Trojan index to reduce network I/O by storing...

An effective dissimilarity measure for clustering of high-dimensional categorical data
Clustering is to group similar data and find out hidden information about the characteristics of dataset for the further analysis. The concept of dissimilarity of objects is a decisive factor for good quality ...

Parallel labeling of massive XML data with MapReduce
The volume of XML data has become enormous and still grows very quickly as many data have been typed in XML by virtue of its simplicity and extensibility. While a tree labeling algorithm has a crucial role in ...

An Edge-Based Framework for Fast Subgraph Matching in a Large Graph
In subgraph matching, we want to find all subgraphs of a database graph that are isomorphic to a query graph. Subgraph matching requires subgraph isomorphism testing, which is NP-complete. Recently, some techn...
