Record Linkage Task

An Entity-Record Linkage Task is a Record Linkage Task that identifies and links entity records referring to the same real-world entity across multiple data sources.

• AKA: Entity Record Matching Task, Entity Record Normalization Task, Entity Resolution Task.
• Context:
  • It can typically process entity databases containing structured data and semi-structured data.
  • It can often employ similarity measures to assess potential record matches.
  • It can utilize entity attributes and contextual information for improved matching accuracy.
  • It can range from being a Heuristic Entity Record Linkage Task to being a Data Driven Entity Record Linkage Task, depending on its matching approach.
  • It can support data integration and data quality improvement efforts.

...

• Examples:

Entity Record Linkage Task Types, such as:

• Person Record Linkage Task for identity resolution.
  • • Product Record Linkage Task for product catalog integration.
• Citation Record Linkage Task for bibliographic deduplication.

Entity Record Linkage Implementations, such as:

• Customer Database Matching Task using probabilistic matching.
  • • Healthcare Patient Linkage Task in clinical environment.
• Business Entity Resolution Task for corporate database integration.
• Counter-Examples:

Relation Record Linkage Task, which links relation tables rather than entity records. Schema Matching Task, which aligns data structures rather than entity instances.

• • Data Deduplication Task, which focuses on exact duplicates rather than entity variations.
