NADEEF/ER: Generic and interactive entity resolution

Entity resolution (ER), the process of identifying and eventually merging records that refer to the same real-world entities, is an important and long-standing problem. We present Nadeef/Er, a generic and interactive entity resolution system, which is built as an extension over our open-source generalized data cleaning system Nadeef. Nadeef/Er provides a rich programming interface for manipulating entities, which allows generic, efficient and extensible ER. In this demo, users will have the opportunity to experience the following features: (1) Easy specification - Users can easily define ER rules with a browser-based specification, which will then be automatically transformed to various functions, treated as black-boxes by Nadeef; (2) Generality and extensibility - Users can customize their ER rules by refining and fine-tuning the above functions to achieve both effective and efficient ER solutions; (3) Interactivity - We also extended the existing Nadeef dashboard with summarization and clustering techniques to facilitate understanding problems faced by the ER process as well as to allow users to influence resolution decisions.
