SAKey - Scalable Tool For Almost Key Discovery in RDF Data

Person in charge : PERNELLE-MANSCOUR Nathalie

A scalable tool that discovers keys (properties that uniquely identify an entity) in RDF data in an efficient way. To prune the search space, SAKey exploits characteristics of the data that are dynamically detected during the process. Furthermore, our approach can discover keys in datasets where erroneous data or duplicates exist (i.e., almost keys). The approach has been evaluated on different synthetic and real datasets. The results show both the relevance of almost keys and the efficiency of discovering them.
