We assume that the uncertain objects are independent to each other. In the following paper, we use object to denote multi-dimensional uncertain object whenever there is no ambiguity. Given an object U, Umbr denotes the minimal bounding ...

We develop an approach to restricting constraint complex value calculus languages with negation to safe formulas that ... For a general introduction to finite model theory, see [5,6]. Constraint databases were introduced in [1].
The ElasTraS design on the other hand utilizes the shared storage model based on append-only distributed file-systems such as GFS [20] or HDFS [25]. The desirable feature of the ElasTraS design is that it supports elasticity of data in ...
insert on different physical column organizations in in-memory column stores and ii) a cache based cost model for each operation and column organization. The remainder of the paper is structured as follows. Section2gives an overview of ...
We provide techniques to incrementally maintain the index and the graph saturation upon the changes to the RDF graph, enabling the framework to cope with dynamic data graphs. Experiment results demonstrate that our techniques ...
Currently, concepts from traditional approaches of federated query processing systems are adapted to provide integrated access to RDF data sources. Basic idea is to query a mediator, which distributes subqueries to local RDF stores and ...
2.3 System Framework The framework (cf. Fig. 1) consisted of three components, including getting the EDP representation of RDF data, generating EDPRule from the ontologies of RDF data, using EDPRule and EDP to detect redundant triples.
Recently, how to evaluate SPARQL queries over federated RDF systems has become a hot research topic. However, most existing studies mainly focus on implementing and optimizing the basic queries over federated SPARQL systems, ...
While Sempala implemented Unified property table which is a single property table consisting of all RDF data. It is mainly designed to entertain the star shape queries in efficient manner. When it translated SPARQL query into SPARQL ...
