Entity Identification in Database Integration
The objective of ent i ty identification i s t o determine the correspondence between object instances f r o m more than one database. This paper ezamines the problem at the instance level assuming that schema level heterogeneity has been resolved a priori . Soundness and completeness are defined as the desired properties of any ent i ty identification technique. To achieve soundness, a set of ...
متن کاملMining Entity-Identification Rules for Database Integration
Entity identification (EI) is the identification and integration of all records which represent he same realworld entity, and is an important task in database integration process. When a common identification mechanism for similar records across heterogeneous databases is not readily available, EI is performed by examining the relationships between various attribute values among the records. We...

The objective of entity identiication is to determine the correspondence between object instances from more than one database. This paper examines the problem at the instance level assuming that schema level het-erogeneity has been resolved a priori. Soundness and completeness are deened as the desired properties of any entity identiication technique. To achieve sound-ness, a set of identity an...
متن کاملEntity Identi cation in Database Integration: An Evidential Reasoning Approach
Entity identiication is the problem of matching object instances from diierent databases which correspond to the same real-world entity. In this paper, we present a 2-step entity identiication process in which attributes for matching tuples may be missing in certain tuples, and thus need to be derived prior to the matching. To match tuples, we require identity rules which specify the conditions...
متن کاملEntity identification for heterogeneous database integration--a multiple classifier system approach and empirical evaluation
Entity identification, i.e., detecting semantically corresponding records from heterogeneous data sources, is a critical step in integrating the data sources. The objective of this research is to develop and evaluate a novel multiple classifier system approach that improves entity identification accuracy. We apply various classification techniques drawn from statistical pattern recognition, mac...
