Distributed Holistic Clustering on Linked Data

Link discovery is an active field of research to support data integration in the Web of Data. Due to the huge size and number of available data sources, efficient and effective link discovery is a very challenging task. Common pairwise link discovery approaches do not scale to many sources with very large entity sets. We propose a distributed holistic approach to link many data sources based on a clustering of entities that represent the same real-world object. Our approach provides a compact and fused representation of entities, and can identify errors in existing links as well as many new links. We support distributed execution, show scalability for large real-world data sets and evaluate our methods with respect to effectiveness and efficiency for two domains.
