Semantic Matching

Semantic matching is a type of ontology matching technique that relies on semantic information encoded in lightweight ontologies to identify nodes that are semantically related in graph-like structures.

Structure Preserving Semantic Matching (SPSM)

SPSM is a type of semantic matching producing a similarity score and a mapping preserving structural properties: (i) one-to-one correspondences between semantically related nodes; (ii) functions are matched to functions and variables to variables.

Minimal mappings

The set of minimal mappings is a subset of all possible semantic mappings such that: i) all the other correspondences can be computed from the ones in the minimal set, and ii) none of the correspondences in the minimal set can be dropped without losing property i).

Lightweight ontologies

Lightweight ontologies provide the formal representation to be able to reason about hierarchical structures such as classifications. Each node's label in the classification is translated into propositional description logic (DL) formula, which univocally codifies the meaning of the node.
