In temporal and multi-version XML environments, several research works have focused on changes to traditional aspects of XML schemas like element/attribute declarations and simple/complex type definitions. However, advanced aspects of XML schemas have ...

Deterministic regular expressions (DREs) are a core part of XML schema languages such as DTD/XSD and are used in different kinds of applications. Presently the most powerful model to learn DREs is k-occurrence regular expressions (k-OREs for short)...

System Entity Structure (SES) is a high-level ontology which was introduced for knowledge representation of decomposition, taxonomy and coupling of systems. It has its roots from the systems theory-based approaches to modeling and simulation. SES has ...

Ontology Web Language (OWL) is considered as a data representation format exploited by the Extensible Markup Language (XML) format. OWL extends XML by providing properties to further express the semantics of data. To this effect, transforming XML data ...

Since lacking valid schemas is a critical problem for XML and present research on interleaving for XML is also quite insufficient, in this paper we focus on the inference of XML schemas with interleaving. Previous researches have shown that the ...

With the rapid development of computer technology, the barriers of communication among different systems caused by system heterogeneity or data structure have been broken down. However, the demands for personalized content for accuracy in resource ...

We study the problem of bounded repairability of a given restriction tree language R into a target tree language T. More precisely, we say that R is bounded repairable with respect to T if there exists a bound on the number of standard tree editing ...

In this paper we consider the problem of repairing, that is, restoring validity of, documents with respect to XML schemas. We formalize this as the problem of determining, given an XML schema, whether or not a streaming procedure exists that transforms ...

Reversing XML Schema to conceptual model has been a center of attention. Previous researchers use hierarchy structure of XML Schema component to generate class diagram. However, hierarchy structure involves only primary XML schema components. Our ...

Web services represent a way to share data and shall be treated as a solution for interoperability between heterogeneous systems. However, by having a public infrastructure, subject to attacks, security issues have become indispensable and challenging. ...

The aims of XML data conversion to ontologies are the indexing, integration and enrichment of existing ontologies with knowledge acquired from these sources. The contribution of this paper consists in providing a classification of the approaches used ...

Schema Matching, i.e. the process of discovering semantic correspondences between concepts adopted in different data source schemas, has been a key topic in Database and Artificial Intelligence research areas for many years. In the past, it was largely ...

Schemas are often used to constrain the content and structure of XML documents. They can be quite big and complex and, thus, difficult to be accessed manually. The ability to query a single schema, a collection of schemas or to retrieve schema ...

The availability of vast amounts of heterogeneous XML web data motivates finding efficient methods to search, integrate, query, and present this data. The structure of XML documents is useful for achieving these tasks; however, not every XML document on ...

We propose a mapping from a database conceptual design to a schema for XML that produces highly connected and nested XML structures. We first introduce two alternative definitions of the mapping, one modeling entities as global XML elements and ...

Today, XML is a standard for message exchange inside and among IT infrastructures. For the exchange to work an XML format must be negotiated between the communicating parties. The format is often expressed as an XML schema. In our previous work, we ...

Recently, plenty of methods dealing with automatic inference of XML schema have been developed, however, most of them utilize XML documents as their only input. In this paper, we focus on extending inference by incorporating XML operations, in ...

X3D has been evolving for nearly 20 years (counting the VRML era). This long period, covering a wide range of uses (Computer-Aided Design, medical, Geographic Information System ...) has led to a lot of possibly inconsistent or even conflicting ...

The use of standards in the geospatial domain, such as those defined by the Open Geospatial Consortium OGC, for exchanging data has brought a great deal of interoperability upon which systems can be built in a reliable way. Unfortunately, these ...

The paper designs and implements the E-Learning Standard Test System. It is composed of three loosely coupled components: XSD translated from the E-Learning standard, the XML parsing and validating package and the test result displaying package.
