Two-layer Representation in Web-agent of EC solution

This paper proposes two layer representations, base-layer and meta-layer representations, used in web-based modeling system. While the representation in base-layer focuses on individual models, the representation in meta layer does on the relationships between models called subordinate relationship in the paper and is absolutely needed to develop web-agent of EC solution. The meta layer is a place where is worked on doing adaptive modeling by extracting the relationships in web-based system. The adaptive modeling is identified by adaptiveness of modeling system for multi-tier user. A variety of knowledge, which enables the system to adaptively behave, is well known. The study presents the concept of the modeling steps, which are User Interface, Chunk Extraction, and Relationship Investigation. The User Interface step proceeds the modeling of users problem. The Chunk Extraction step handles meta-level knowledge, i.e. subordinate relationship between models. Finally, the Relationship Investigation step manages diverse models in the system and generates the subordinate relationships among the models.
