View Selection in Semantic Web Databases
We consider the setting of a Semantic Web database, containing both explicit data encoded in RDF triples, and implicit data, implied by the RDF semantics. Based on a query workload, we address the problem of selecting a set of views to be materialized in the database, minimizing a combination of query processing, view storage, and view maintenance costs. Starting from an existing relational vie...
متن کاملMaterialized View Selection in XML Databases
Materialized views, a rdbms silver bullet, demonstrate its efficacy in many applications, especially as a data warehousing/decison support system tool. The pivot of playing materialized views efficiently is view selection. Though studied for over thirty years in rdbms, the selection is hard to make in the context of xml databases, where both the semi-structured data and the expressiveness of xm...
متن کاملA procedure for Web Service Selection Using WS-Policy Semantic Matching
In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...
متن کاملIntroducing Context into Semantic Web Knowledge Databases
Knowledge Representation in the Semantic Web is mainly characterized by the capabilities of the languages OWL and RDF. When attacking non-trivial problems such as the creation and maintenance of large-scale knowledge bases in RDF, it becomes evident that RDF lacks a central feature, namely the capability of restricting the truth value of a statement to a context, with far-reaching consequences ...
متن کاملCDL-based Semantic Representation for Web Databases
One important task toward making web machine understandable is representing web data into semantic formats. Since a huge amount of web data stored in databases, researchers pay much care to convert DB to semantic format. Most of the previous work depends on domain ontology to covert DB to RDF. However, depending on domain ontology has many problems. This paper proposes converting web DBs into C...
