Towards Graphical Query Notation for Semantic Databases
نویسندگان
چکیده
We describe a notation and a tool for schema-enabled visual/diagrammatic creation of SPARQL queries over RDF databases. The notation and the tool support both the standard basic query pattern comprising a main query class and possibly linked condition classes and means for aggregate query definition and placing conditions over aggregates including also aggregation of aggregate results. We discuss the applicability of the tool for adhoc query formulation in practical use cases.

Towards a Unified Query-by-Example (UQBE): UML as a Basis for a Generic Graphical Query Language
A generic graphical query language for ODMG-compliant object databases is proposed, based on the ideas of Query-By-Example, and using UML-like diagrams as schema notation. Ease of learning for users coming from the relational world and support for non object-oriented data sources are also considered as design goals. The overall layout of the query language is described, illustrating its potenti...
متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...

In this paper we show how semantic web technologies are used in a real application in the domain of national medical databases where an important technological gap between the legacy relation databases and OWL ontologies is bridged by the recently standardized UML profile for OWL. After data has been exported from multiple relational databases into a single shared RDF database structured accord...

متن کاملMapping ORM into the SHOIN/OWL Description Logic -Towards a Methodological and Expressive Graphical Notation for Ontology Engineering
We map ORM into the SHOIN /OWL, which is the most common description logic in ontology engineering. As SHOIN /OWL is known to be a good compromise between expressiveness and computational complexity, this implies that the ORM constraints mapped in this paper are the constraints that are easier to implement and reason about. Our mappings are implemented as an extension to the DogmaModeler tool, ...
