The ongoing trend towards open data embraced by the Semantic Web has started to produce a large number of data sources. These data sources are published using RDF vocabularies, and it is possible to navigate throughout the data due to their graph topology. This paper presents LinksB2N, an algorithm for discovering information overlaps in RDF data… (More)
The interdisciplinary nature of the Semantic Web and the many projects put forward by the community led to a large number of widely accepted serialization formats for RDF. Most of these RDF syntaxes have been developed out of a necessity to serve specific purposes better than existing ones, e.g. RDFa was proposed as an extension to HTML for embedding… (More)
The classification of products and services enables reliable and efficient electronic exchanges of product data across organizations. Many companies classify products (a) according to generic or industry-specific product classification standards, or (b) by using proprietary category systems. Such classification systems often contain thousands of product… (More)
Design-pattern driven ontology construction, whether manual or (partially) automated, relies on the availability of curated repositories of Ontology Design Patterns (ODPs) adequately characterized. In order to consistently apply a given ODP, not only it is important to characterize it in full, but also examine its alignment or deviation to other relevant… (More)
To date, the automatic exchange of product information between business partners in a value chain is typically done using Business-to-Business (B2B) catalog standards such as EDIFACT, cXML, or BMEcat. At the same time, the Web of Data, in particular the GoodRelations vocabulary , offers the necessary means to publish highly-structured product data in a… (More)
To assist ontology developers modeling complex domain concepts , a comparative analysis of two Ontology Design Patterns (ODPs) has been carried out. As a result, terminology is introduced to characterize certain role and reusability scenarios of class hierarchies in ODPs. An example that benefits from this study is provided.
In this paper, we describe the technical approach of and experiences gained in exposing a major share of the European building and construction materials market on the basis of the GoodRelations Web vocabulary for e-commerce. This allows for the fine-grained search for products, suppliers, and warehouses for any building-related sourcing needs. Because… (More)
Most ontologies used in e-commerce are nowadays taxonomies with simple structure and loose semantics. One exception is the OPDM collection of ontologies, which express rich information about product categories and their parameters for a number of domains. Yet, having been created by different designers and with specific bias, such ontolo-gies could still… (More)
