Table 22 FCA-based ontology merging and matching systems
From: Matching biomedical ontologies based on formal concept analysis
| FCA-based systems for ontology merging or matching | Object in the formal context | Attribute in the formal context | Binary relation in the formal context | |
|---|---|---|---|---|
| FCA-Merge, FFCA-Merge (merging) | Textual document | Class from two ontologies | Name of class occurs in document | |
| [22,25,26] (matching) | Ontology class | Thesaurus term | Term occurs in class | |
| FCA-OntMerge (merging) | Class from two ontologies | Attribute from two ontologies | Class has attribute | |
| FCA-Map (matching) | Step 1: lexical matching | Name, label, or synonym of classes from two ontologies | Token | String contains token |
| Step 2: structural validation | Class from two ontologies | Lexical anchor prefixed with a relation | Class has relation with anchor | |
| Step 3: structural matching | Class from two ontologies | Validated anchor prefixed with a relation | Class has relation with validated anchor | |
| Step 4: property matching | Property from two ontologies | A pair of anchors | Property links the individuals of two anchors | |
| Step 5: extended structural matching | Class from one ontology | Class from another ontology | Two classes across ontologies occur in the anonymous ancestors of the same anchor with the same property |
