Adaptors, Bridges, and Connectors
The ABC of adaptation: Towards a software architecture for adaptation-centered CBR systems
Enric Plaza and Josep-Lluís Arcos
Abstract
We present a software architecture model of adaptation in CBR. A software
architecture is defined by its components and their connectors. We present
a software architecture for CBR systems based on three components (a task
description, a domain model, and adaptors) connected by a type of
connectors called bridges.
Adaptors are basic inference components that perform specific
transformations to cases. Two kinds of adaptors are introduced: domain
adaptors (d-adaptors) and case-based adaptors (c-adaptors).
Adaptors are applied to a given problem, performing search until a sequence
of adaptor instantiations is found such that a solution is achieved. Thus,
in the ABC architecture adaptation is
viewed as a search process on the space of adaptors. We describe how the
ABC components have been used in the
SaxEx application, a CBR system for
generating expressive musical phrases.
