Abstract

The main objective of Entity resolution (ER) is to find duplicate records within the same data table from the same source or different data tables from various sources. A traditional pair-wise supervised entity resolution matching depends on pre-built rules for finding matched records. On the other hand, unsupervised or semisupervised also relies on pair-wise matching. In the maximum case, group membership is left behind for consideration. In this dissertation, I have discussed the design, implementation and evaluation of a graph-based entity resolution for group membership to enhance the pair-wise matching ER system. I have designed and implemented a pipeline for blocking, then clustering using Datawashing machine for a dataset and used the graph technique to find matching based on group membership. I have implemented this technique on synthetic data where the data set is first run through a pair-wise matcher, namely OYSTER. After that, Graph-based Group membership pipeline was used to enhance that pair-wise result, where we observed significant enhancement for the True Positive linkage.
