Transfer-based MT

Definition
MT systems which analyse the source text into a syntax tree and then convert the tree into the form required by the target syntax (for example, moving the verb complex) or analyse the source text into some formalism that is intended to capture meaning, not just grammatical form.
Metrics

Metric: The developer should provide a description of the theory and method of translation used by the system. -- Method: Receipt and review of the specification of the transfer method. -- Measurement: 1) Yes or no: Is the system a transfer translation system? 2) At what level of transfer does the system operate primarily?

Metric: If the system uses a grammar, the form and number of grammatical analysis rules -- Method: Receipt and review of the grammatical rules in place -- Measurement: 1) Yes or no: Do the grammatical rules exist? 2) What number of grammatical rules exist?

Metric: If the system uses a grammar, the coverage of the grammatical rules -- Method: (a) Receipt and review of the grammatical rules in place -- Measurement: (a) Analyzed coverage of grammatical rules for number of phenomena covered.

Method: (b) Use test suite to test for grammatical phenomena coverage -- Measurement: (b) Number of test suite cases covered

Metric: If the system uses a grammar, the relaxation capacity -- Method: (a) Receipt and review of the grammatical relaxation algorithm -- Measurement: (a) Analyzed coverage of relaxation algorithm for number of phemomena covered

Method: (b) Use test suite to test for grammatical relaxations -- Measurement: (b) Number of test suite cases covered

Metric: If the system uses a grammar, the ease of adding or changing the rules -- Method: Add or change a grammar rule -- Measurement: Yes or no: Can the grammar be changed? --

NOTE: This is related to section 2.2.5.2.

Metric: With respect to the transfer component, the form and number of transfer rules -- Method: Receipt and review of the transfer rules -- Measurement: 1) The transfer rules are described in a standardized form. 2) Number of transfer rules

Metric: With respect to the transfer component, the coverage of transfer rules -- Method: (a) Receipt and review of the transfer rules -- Measurement: (a) Analyzed coverage of transfer rules for number of phenomena covered.

Method: (b) Use test suite to test for transfer phenomena coverage -- Measurement: (b) Number of test suite cases covered

Metric: With respect to the transfer component, the relaxation capacity of the transfer rules -- Method: (a) Receipt and review of the relaxation mechanism for the transfer rules -- Measurement: (a) Analyzed coverage of the relaxation mechanism in transfer

Method: (b) Use test suite to test for transfer rule relaxation -- Measurement: (b) Number of test suite cases covered

Metric: With respect to the transfer component, the ease of adding or changing the rules -- Method: Add or change transfer rules -- Measurement: Yes or no: Can transfer rules be added or changed?
