Generic Schema Matching with Cupid

by Jayant Madhavan, Philip Bernstein, Erhard Rahm - In The VLDB Journal , 2001
"... Schema matching is a critical step in many applications, such as XML message mapping, data warehouse loading, and schema integration. In this paper, we investigate algorithms for generic schema matching, outside of any particular data model or application. We first present a taxonomy for past s ..."

COMA - A system for flexible combination of Schema Matching Approaches

by Hong-hai Do, Erhard Rahm - In VLDB , 2002
"... Schema matching is the task of finding semantic correspondences between elements of two schemas. It is needed in many database applications, such as integration of web data sources, data warehouse loading and XML message mapping. To reduce the amount of user effort as much as possible, automati ..."

Ontologies: Silver Bullet for Knowledge Management and Electronic Commerce

by Dieter Fensel , 2007
"... Currently computers are changing from single isolated devices to entry points into a world wide network of information exchange and business transactions called the World Wide Web (WWW). Therefore support in the exchange of data, information, and knowledge exchange is becoming the key issue in cur ..."

in current computer technology. Ontologies provide a shared and common understanding of a domain that can be communicated between people and application systems. Therefore, they may play a major role in supporting information exchange processes in various areas. This book discusses the role ontologies

Reconciling Schemas of Disparate Data Sources: A Machine-Learning Approach

by Anhai Doan, Pedro Domingos, Alon Halevy - In SIGMOD Conference , 2001
"... A data-integration system provides access to a multitude of data sources through a single mediated schema. A key bottleneck in building such systems has been the laborious manual construction of semantic mappings between the source schemas and the mediated schema. We describe LSD, a system that empl ..."

XMark: A Benchmark for XML Data Management

by Albrecht Schmidt, Florian Waas, Martin Kersten, Michael J. Carey, Ioana Manolescu, Ralph Busse - In VLDB , 2002
"... While standardization efforts for XML query languages have been progressing, researchers and users increasingly focus on the database technology that has to deliver on the new challenges that the abundance of XML documents poses to data management: validation, performance evaluation and optimi ..."

From XML schema to relations: A cost-based approach to XML storage

by Phil Bohannon, Juliana Freire, Prasan Roy, Jérôme Siméon - In ICDE , 2002
"... bohannon,juliana,prasan,simeon¡ XML has become an important medium for data representation, particularly when that data is exchanged over or browsed on the Internet. As the volume of XML data increases, there is a growing interest in storing XML in relational databases so that the well-developed fea ..."
Abstract - Cited by 152 (13 self) - Add to MetaCart
presents interesting challenges. LegoDB is a cost-based XML-to-relational mapping engine that addresses this problem. It explores a space of possible mappings and selects the best mapping for a given application (defined by an XML Schema, XML data statistics, and an XML query workload). LegoDB leverages

Taxonomy of xml schema languages using formal language theory

by Makoto Murata, Dongwon Lee, Murali Mani - EXTREME MARKUP LANGUAGES , 2001
"... On the basis of regular tree grammars, we present a formal framework for XML schema languages. This framework helps to describe, compare, and implement such schema languages in a rigorous manner. Our main results are as follows: (1) a simple framework to study three classes of tree languages (local, ..."

XML-Based XML Schema Access

by Erik Wilde, Felix Michel, Eth Zürich - In Poster Proceedings of the 16th International World Wide Web Conference , 2007
"... XML Schema’s abstract data model consists of components, which are the structures that eventually define a schema as a whole. XML Schema’s XML syntax, on the other hand, is not a direct representation of the schema components, and it proves to be surprisingly hard to derive a schema’s components fro ..."
