ERGP: A Combined Entity Resolution Approach with Genetic Programming

Entities often hold more than one representation with some expressive errors in different data sources in the real world. Different representations and a few possible expressive errors make entities identifying a crucial task in data integration and data cleaning, which is known as entity resolution. We propose a novel approach for entity resolution using genetic programming named Entity Resolution with Genetic Programming (ERGP). ERGP is able to learn to get an effective entity resolution classifier by combining several different properties´ comparisons. The evaluation shows that ERGP outperforms the state-of-the-art entity resolution algorithms. Above all the ERGP approach is capable of setting the threshold for each single comparison of an attributes´ pair, leaving no burden of setting thresholds to the user.
