The Ontology Directed Matcher (ODM) application simplifies the process of comparing two sets of objects based on their common attributes. The user supplies the Matcher with both sets of objects contained in a single ontology and then utilizes the Matcher to create and edit criteria to guide the matching process.
Matcher Key Features:
- Ability to match against a subset of the source set
- Simple GUI allows the user to specify and edit match criteria
- Cutoff can be specified as part of the matching criteria to trim the results
- Implements AQL validation using ANSI/ASQC Z1.4
- Multi-valued attributes can be compared using conjunction or disjunction over the values
- Weights can be associated with attributes to give precedence to one attribute over the other
- Comes bundled with matching functions:
- Company Name Matching: Uses minimum edit distance algorithm, along with name standardization to match company names
- String Matching: Utilizes least common subsequence algorithm to match strings
- Measurement Matching: Able to compare measures from English, U.S. and Metric systems
- Trie Matching: Uses ontology structure to match elements in the ontology
- Zip code and phone number matching
- The Matcher intuitively determines the most appropriate matching function to use for an attribute by using information from the ontology; the user can override this automatic selection as required
- Extensible framework allows for new matching functions to be added
- Matching criteria can be saved and reused for new data sets
- Object data can be imported into an existing ontology by using ODBC interface
- Match results can be saved in different formats such as delimited text file or to a database supporting ODBC
