There are many problems requiring a semantic account of a database
schema. At its best, such an account consists of mapping formulas between the
schema and a formal conceptual model or ontology (CM) of the domain. This
paper describes the underlying principles, algorithms, and a prototype of a tool
which infers such semantic mappings when given simple correspondences from
table columns in a relational schema to datatype properties of classes in an on-
tology. Although the algorithm presented is necessarily heuristic, we offer formal
results stating that the answers returned are “correct” for relational schemas de-
signed according to standard Entity-Relationship techniques. We also report on
experience in using the tool with public domain schemas and ontologies.
