Systems and methods for automatically and generically matching models are provided, such as may be provided in a matching application or matching component, or provided in a general purpose system for managing models. The methods are generic since the methods apply to hierarchical data sets outside of any particular data model or application. Similarity coefficients are calculated for, and mappings are discovered between, schema elements based on their names, data types, constraints, and schema structure, using a broad set of techniques. Some of these techniques include the integrated use of linguistic and structural matching, context dependent matching of shared types, and a bias toward subtree, or leaf, structure where much of the schema content resides.

A method, system and computer program product for transformation, normalization and correlation techniques that are effective for matching names of foreign origin that may be spelt in any number of ways. It addresses the problem of matching names that may belong to the same person but may be spelt differently. The main technique is to convert both strings to be matched into a representation of their original language, i.e., transform them into idealized (normalized) versions of themselves based on their true spelling in their original, native language. This process of idealization can be done either by employing a dictionary of standard, idealized names, or by implementing the idealization in real time by following a finite-state algorithm to convert the strings into their true representation in their original language. The idealization process can be viewed as a phonetic searching method, as it resolves the problem of vowel representations or their incorrect use as well as handling the representation of consonants that do not exist in the English language. Further probabilistic and elastic matching techniques, using a correlation function, can be invoked manually or automatically to match names where the quality of or the completeness of names may be suspect. A new approach to "probabilistic" and "sliding-elastic" matching (which give a level of confidence as a percentage against each match) can be used with or without the phonetic (idealized) searching function. The results of the search are displayed on the computer screen or printed, showing all the successful matches, together with the type of search that has been used to obtain the match. Results can be filtered by comparing attributes of the persons associated with the Suspect and Data names (such as age, country of birth, etc.) to minimize reporting on irrelevant matches.
