Data Set Used
In this paper we discuss the design and implementation of voiD, the " Vocabulary Of Interlinked Datasets " , a vocabulary that allows to formally describe linked RDF datasets. We report on use cases for voiD, the current state of the specification and its potential applications in the context of linked datasets.
Datasets in the LOD cloud are far from being static in their nature and how they are exposed. As resources are added and new links are set, applications consuming the data should be able to deal with these changes. In this paper we investigate how LOD datasets change and what sensible measures there are to accommodate dataset dynamics. We compare our… (More)
In this paper, we introduce interlinking multimedia (iM), a pragmatic way to apply the linked data principles to fragments of multimedia items. We report on use cases showing the need for retrieving and describing multimedia fragments. We then introduce the principles for interlinking multime-dia in the Web of Data, discussing potential solutions which… (More)
—While Linked Open Data (LOD) has gained much attention in the recent years, requirements and the challenges concerning its usage from a database perspective are lacking. We argue that such a perspective is crucial for increasing acceptance of LOD. In this paper, we compare the characteristics and constraints of relational databases with LOD, trying to… (More)
When attempting to build a scaleable Semantic Web application, one has to know about the size of the Semantic Web. In order to be able to understand the characteristics of the Semantic Web, we examined an interlinked dataset acting as a representative proxy for the Semantic Web at large. Our main finding was that regarding the size of the Semantic Web,… (More)
Although the cloud of Linked Open Data has been growing continuously for several years, little is known about the particular features of linked data usage. Motivating why it is important to understand the usage of Linked Data, we describe typical linked data usage scenarios and contrast the so derived requirement with conventional server access analysis.… (More)
Semantic Web technologies are around now for a while, already. However, in the development of real-world Web applications these technologies have considerable little impact to date. With linked data this situation has changed dramatically in the past couple of months. This article shows how linked datasets can be exploited to build rich Web applications… (More)
