Definition

Entity Resolution is the task of analyzing a collection of data (e.g., database, data set) in order to create entities by merging the data instances that describe the same real-world objects. Uncertain entity resolution is a group of resolution methodologies focusing on handling the uncertainties that are present either in the data or are generated during the resolution process.

Historical Background

The fundamental component of resolution techniques is an instance that provides some characteristic of a real-world object. An instance is a tuple with k attributes 〈v1, …, vk〉, with each attribute being one characteristic of the corresponding object. Consider now a collection of instances. The goal of resolution is to detect the instances that describe the same real-world objects and merge them into entities, i.e., create entity e for representing instances r1, r2, and r3.

The initial resolution approaches focused on handling the...
