Translation Coverage Matrix
- standardized rule representation allows us to easily analyze the
translation coverage
- table represents mappings from data ontology properties (rows) to domain ontology properties (columns)
- empty columns reflect information gaps
- columns > 1 reflect potential conflicts
- empty rows reflect unused information
- example
- company name mapped from each source
- NASDAQ doesn't provide homepage
- NYSE and NASDAQ don't provide current price
- possible future directions
- improved GUI interface
- aggregate by ontology and/or class
- click cell to view/define rule
