Linkage Rule
A linkage rule specifies how two data items are compared for similarity. A linkage rule consists of four basic components:
-
Path Input Retrieves values from a entity by a given RDF path e.g.
?movie/dbpedia:director/rdfs:label -
Transformation Applies a data transformation to all values e.g.
lowerCase - Comparison Evaluates the similarity of two inputs based on a user-defined distance measure and returns a confidence.
- Aggregation Aggregates multiple confidence values.
