An Efficient approach for finding the essential experts in Digital Library

Abstract

Name ambiguity is a special case of identity uncertainty where one person can be referenced by multiple name variations in different situations or even share the same name with other people. In this paper, we focus on Nam e Disambiguation problem. When non - unique values are used as the identifier of Entities, due to their homonym, confusion can occur. In particular, when (part of ) "names" of entities are used as their identifier, the problem is often referred to as the name disambiguation problem, where goal is to sort out the erroneous entities due to name homonyms (e.g., if only last name is used as the identifier, one cannot distinguish "Vannevar Bush" from "George Bush"). We formalize the problem in a unified probabilistic framework and propose a algorithm for parameter estimation. We use a dynamic approach for estimating the number of people K and for finding the experts in digital library by counting the number of accesses of the paper.
