SERIMI - Resource Description Similarity, RDF Instance Matching and Interlinking [article]

Samur Araujo, Jan Hidders, Daniel Schwabe, Arjen P. de Vries
2011 arXiv   pre-print
SERIMI matches instances between a source and a target datasets, without prior knowledge of the data, domain or schema of these datasets.  ...  In this paper, we propose a novel interlinking method, SERIMI, for solving this problem automatically.  ...  This means that, in RDF, the schema matching (e.g. ontology alignment) is not always necessary and sufficient for achieving RDF instance matching and interlinking.  ...

SERIMI results for OAEI 2011

Samur Araújo, Arjen P. de Vries, Daniel Schwabe
2011 International Semantic Web Conference  
We first describe the basic interlinking process and interlinking strategies in SERIMI, and then we present specific techniques used in this track.  ...  We conclude with a discussion of our results, and possible directions to improve SERIMI in future work.  ...  In this context, ontology matching [2, 3, 4, 5, 6] and instance matching [9] are the two most-studied sub-problems of interlinking.  ...

Interlinking Linked Data Sources Using a Domain-Independent System [chapter]

Khai Nguyen, Ryutaro Ichise, Bac Le
2013 Lecture Notes in Computer Science  
Finally, SLINT+ uses selected predicate alignments as the guide for generating candidate and matching instances.  ...  Traditional methods compare two instances by predefined pairs of RDF predicates, and therefore they rely on the domain of the data.  ...  SERIMI [1] selects the useful predicates and their alignments by considering the entropy and the similarity of RDF objects.  ...

Learning approach for domain-independent linked data instance matching

2012 Proceedings of the ACM SIGKDD Workshop on Mining Data Semantics - MDS '12  
First, we compute the similarity vectors between labeled pairs of instances without specifying the meaning of the RDF predicates.  ...  Recently, instance matching has been used to identify owl:sameAs links between linked datasets.  ...  To estimate the correlation of two instances, RDF-AI chooses the highest value of similarities between all pairs of interlinked resources.  ...

With rapid expansion in size and diversity, it consists of over 800 interlinked datasets with over 60 billion triples.  ...  However, two of the key obstacles in using the LOD cloud are the limited support for data integration tasks over concepts, instances, and properties, and relevant data source selection for querying over  ...  Property alignment has two components: data-type and objecttype property alignments. Object-type properties are the ones having RDF resources as both subject and object of the property.  ...
