Abstract

It is not an easy task for a data owner to publish a dataset as Linked Data with connections to existing datasets since there are too many datasets, thus it is hard to find the related ones, to download them and to check their content (let alone to apply entity matching over them). However, the connections with other datasets are important for discoverability, browsing, and querying in general. To alleviate this problem in this paper we introduce LODChain, a service that can help a provider to strengthen the connections between his/her dataset and the rest of datasets. LODChain finds the common entities, schema elements and triples among the dataset at hand and hundreds of LOD Datasets and through equivalence reasoning it suggests to the user various inferred connections, as well as related datasets. In addition, it detects erroneous mappings, and offers various content-based dataset discovery services, for enabling the enrichment of datasets’ content. The key difference with the existing approaches is that they are metadata-based, while what we propose is data-based. We present an implementation of LODChain, and we report various experimental results over real and synthetic datasets.
