• SYSTEM: I-SME

Inspired by Keane and Bradshaw's (1988) IAM model and incremental mapping in PHINEAS.

There's some discussion of what about incremental mapping should be seriel and what should be parallel, then about the role of pragmatic constraints. [314]

"When I-SME is given every item in the base and target at the same time, its results are identical to those of SME."

Major features: [315]

• can determine which previous results are still valid
• default operation: extend mapping
• the remap operation backtracks. (the system does not automatically do this because remapping is task specific.)

• required: exclude a mapping that is not one to one.
• identical-functions: only identical functions.

Example 2: MARS. comparing a worked example and a problem to be solved. [317]

Summary author's notes:

• In Covlan, sequential simages are made up of different symbols. I-SME extends a given mapping with new information. So to handle Covlan's representation, it would have to use the horizontal mapping given find what changed, turn the next simage into the symbols of the first, plus whatever new is added, then add the new stuff to the incremental mapper. Then it would have to turn it all back into the symbols used in the next simage again.
