In recent years, the Web has evolved from a global information space of linked documents to a space where data are linked as well. The Linking Open Data (LOD) project has enabled a large number of semantic datasets to be published on the Web. Due to the open and distributed nature of the Web, both the schema (ontology classes and properties) and instances of the published datasets may have hete...

As the number of publicly-available datasets are likely to grow, the demand of establishing the links between these datasets is also getting higher and higher. For creating such links we need to match their schemas. Moreover, for using these datasets in meaningful ways, one often needs to match not only two, but several schemas. This matching process establishes a (potentially large) set of att...

In this paper, we describe an in-progress effort to augment the data integration capabilities of a service-oriented data integration product with the advanced matching capabilities of a knowledgebased schema matching workbench, thereby providing a guided, interactive, and “what”-oriented design environment for use by data architects and integration engineers. The data integration product is the...

Statistical data consists mostly of numerical values, entries of codelists like country codes or acronyms for gender. Such values are typically described according to specific patterns. In this paper we present a novel approach for instance-based schema matching, where regular expressions are utilized for matching patterns of instance values. 1 Motivation and Background In various domains, e.g....

Integrasi data kini telah menjadi kebutuhan bagi setiap organisasi. Organisasi yang tidak mengintegrasikan antara satu divisi dengan lainnya akan menimbulkan kemungkinan terjadinya redundansi dan konsisten. Proses integrasi umumnya terkendala oleh penggunaan istilah penulisan nama tabel serta atribut berbeda. Dalam penelitian ini, metode Linguistik dikombinasikan Constraint digunakan untuk mene...

Recent research has taken advantage of Wikipedia’s multilingualism as a resource for cross-language information retrieval and machine translation, as well as proposed techniques for enriching its cross-language structure. The availability of documents in multiple languages also opens up new opportunities for querying structured Wikipedia content, and in particular, to enable answers that stradd...

The population of ontologies with real instances still remains a major practical issue for the Semantic Web community. Significant progress towards a solution for this issue can be achieved through the migration of data stored in existing relational databases. In this paper we present a schema matching methodology and its implementation, necessary for further data migration. AIS SIGSEMIS BULLET...

The rapidly growing number of autonomous data sources on the web makes the need of effective tools of creating semantic mappings increasingly crucial. Moreover, the goal of allowing applications to have more expressive semantics requires a change in focus. While most previous work focus on creating mappings in specific data models for data transformation, they fail to capture a richer set of po...

The integration of different data structures e.g. relational databases of information systems is a current issue in the area of information sciences. Numerous solutions aroused recently aiming to achieve a high accuracy in similarity measurement and integration of schema entities coming from different schemas. Researches usually properly evaluate the capabilities of these approaches from the po...
