Semantic Query Formulation and Evaluation for XML Databases
- A semantic query attempts to help a user to obtain or manipulate data in a database without knowing its detailed syntactic structure. Formulation and evaluation of semantic queries require schematic and other constraint information as well as general domain knowledge. A new approach to the formulati

Query Formulation and Evaluation for XML Databases
- The proposed approach to XML query formulation and evaluation developed by means of XML Declarative Description (XDD) theory formalizes a query as an XDD description comprising one or more XML clauses the syntax of which can be subdivided into the three specifications: pattern of XML elements to be

Semantic Web Modeling and Programming with XDD
- XML Declarative Description (XDD) is a unified modeling language with well-defined declarative semantics. It employs XML as its bare syntax and enhances XML expressive power by provision of mechanisms for succinct and uniform expression of Semantic Web contents, rules, conditional relationships, int

Towards a Foundation for XML Document Databases
- This paper develops a theoretical framework for modeling and managing XML documents by employment of Declarative Description (DD) theory. In the framework, the de nition of an XML element is formally extended by incorporation of variables in order to represent inherent implicit information and enhan

An Equivalent-Transformation-Based XML Rule Language
- This paper proposes XML Equivalent Transformation (XET) as an XML-based rule langauge for the Web, which seamlessly integrates human-readable documents and computer-interpretable programs by considering XML documents and XML expressions---an extension of ordinary XML elements with variables---as

Unified Representation for EGovernment Knowledge Management
- Abstract. Every governmental office requires knowledge, in order to increase its effectiveness. Hence, there exists need for a representation scheme to represent all types of governmental knowledge: factual, terminological, inferential, and regulated knowledge. Such a scheme must be Web-based suppor

A Foundation for XML Document Databases: DTD Modeling
- XML Document Type Declarations (DTDs) and document validity are crucial notions to the implementation of a variety of XML-based applications. By employment of XML Declarative Description theory, this paper develops a formalism for specification of an XML document's grammatical constraints imposed by

RDF Declarative Description (RDD): A Language for Metadata
- RDF Declarative Description (RDD) is a meta-data modeling language which extends RDF(S) expressiveness by provision of generic means for succinct and uniform representation of metadata, their relationship, rules and axioms. Through its expressive mechanism, RDD can directly represent all RDF-based l

Query Processing of Integrated XML Databases
- Query processing of integrated XML databases has recently received considerable attention. It helps users to extract information from an integrated XML databases system. A flexible and efficient framework for such query processing is proposed. Through a single request, without concern about their in
