By specifying that published datasets must link to other existing datasets, the 4th linked data principle ensures a Web of data and not just a set of unconnected data islands. We propose in this paper the term data linking to name the problem of finding equivalent resources on the Web of linked data. In order to perform data linking, many techniques were developed, finding their roots in statistics, database, natural language processing and graph theory. We begin this paper by providing background information and terminological clarifications related to data linking. We then provide a comprehensive survey over the various techniques available for data linking. We classify these techniques along the three criteria of granularity, type of evidence, and source of the evidence. Finally, we survey eleven recent tools performing data linking and we classify them according to the surveyed techniques.
A comprehensive survey of techniques for data linking can be found in REF .
