Multi-source entity resolution

Bookmark and Share

In this report our main target is multi-source entity resolution in the setting of pair-wise data integration. Unlike the majority of present solutions to entity resolution this study will not consider matching to be transitive. A result of this is that entity resolution on multiple sources will not be confirmed to be associative. The intention of this study ended up being to create a universal model for multi-source entity resolution in the setting of pair-wise data integration that is associative. The primary contributions of this investigation are: (1) an elegant model for multi-source entity resolution and (2) techniques that could be utilized to fix matching conficts in such a way that makes multi-source entity resolution to be associative. The potential worlds semantics is utilized to deal with uncertainty caused by possible matches.
