[Post from Infoglide] Reference Linking Methods - Part 3
“This is the third in a series of four posts that discuss four methods for linking references. These methods are:
- Direct matching
- Transitive linking
- Linking by association
- Asserted Linking
In the last post I discussed transitive linking, and why it is essential for producing a unique and deterministic outcome of an ER process. In this post I will discuss the third method, linking by association.”
BeyeNETWORK: Computed Attributes, Entity Resolution and Connectivity Hierarchies
“There are many types of relationships that are discovered as a by-product of entity resolution, such as households or families. These terms take on different meaning depending on the subject area and the business situation. For example, we can examine parent-child and sibling relationships associated with individuals, we can look at components such as paper clips or screws that are in the same ‘family,’ or we can look at corporate ownership relationships that reflect families of companies. Alternatively, we can look at other types of relationships – individuals belonging to the same health club, components manufactured from the same type of metal, or companies that share the same board members.”
WTVM: Phenix City doctor accused of multi-million dollar Medicare fraud
“In an 80-page civil complaint, the United States Attorney’s Office claims 51-year-old Doctor Robert Ritchea, a physician, not only allowed an unlicensed medical assistant to inject patients with pain medications, but also improperly billed Medicare for the treatments. The complaint also alleges Ritchea over-billed Medicare by more than $2.2 million in over 4,300 separate claims over a period of four years.”
Liliendahl on Data Quality: Location, Location, Location
“If you know that 123 Main Street in Anytown is a single family house there is a high probability that this is the same real world individual. But if you know that 123 Main Street in Anytown is a building used as a nursing home, a campus or that this entrance has many apartments or other kind of units, then it is not so certain that these records represents the same real world individual (not at least if the name is John Smith). So this example highlights the importance of using external reference data in data matching.”
