Exploiting XML Schema for Interpreting XML Documents as RDF [PDF]
2008 IEEE International Conference on Services Computing, 2008 Interpreting legacy XML documents is a great challenge for realizing the vision of the semantic Web (SW). This paper presents an algorithm to transform XML data into RDF- foundation language of the SW - automatically. Our approach maps element definitions stored in XML schema to RDF schema ontology, where the ontology is used to describe the meaning ...

PRSC: From PG to RDF and back, using schemas [PDF]
Semantic WebProperty graphs (PG) and RDF graphs are two popular database graph models, but they are not interoperable: data modeled in PG cannot be directly integrated with other data modeled in RDF. This lack of interoperability also impedes the use of the tools of one model when data are modeled in the other.

Containment of Shape Expression Schemas for RDF [PDF]
arXiv, 2018 We study the problem of containment for shape expression schemas (ShEx) for RDF graphs. We identify a subclass of ShEx that has a natural graphical representation in the form of shape graphs and their semantics is captured with a tractable notion of embedding of an RDF graph in a shape graph.

Deriving an Emergent Relational Schema from RDF Data [PDF]
Proceedings of the 24th International Conference on World Wide Web, 2015 We motivate and describe techniques that allow to detect an "emergent" relational schema from RDF data. We show that on a wide variety of datasets, the found structure explains well over 90% of the RDF triples. Further, we also describe technical solutions to the semantic challenge to give short names that humans find logical to these emergent tables ...

Sorted Neighborhood for Schema-Free RDF Data [PDF]
, 2015 Entity Resolution ER concerns identifying pairs of entities that refer to the same underlying entity. To avoid $$On^2$$ pairwise comparison of n entities, blocking methods are used. Sorted Neighborhood is an established blocking method for Relational Databases.

Interpreting XML documents via an RDF schema [PDF]
Proceedings. 13th International Workshop on Database and Expert Systems Applications, 2002 One of the major problems in the realization of the vision of the ``Semantic Web''; is the transformation of existing web data into sources that can be processed and used by machines. This paper presents a procedure that can be used to turn XML documents

Relational schema optimization for RDF-based knowledge graphs
Information Systems, 2021 Abstract Characteristic sets (CS) organize RDF triples based on the set of properties associated with their subject nodes. This concept was recently used in indexing techniques, as it can capture the implicit schema of RDF data. While most CS-based approaches yield significant improvements in space and query performance, they fail to perform well ...

Building RDF-Schema Based Knowledge Map for Knowledge Management Systems [PDF]
Journal of Systemics, Cybernetics and Informatics, 2003 This paper attempts to implement the semantic web paradigm, which enables the semantic search of knowledge and information on the web environment, by adopting RDF, RDF-schema and Dublin core data element structure in the process of building knowledge map.

Using RDF to Model the Structure and Process of Systems [PDF]
InterJournal of Complex Systems, 2131, ISSN: 1081-0625, February
2008, 2007 Many systems can be described in terms of networks of discrete elements and their various relationships to one another. A semantic network, or multi-relational network, is a directed labeled graph consisting of a heterogeneous set of entities connected by a heterogeneous set of relationships.
