By Peter P. Chen, Leah Y. Wong

This quantity incorporates a number of the papers awarded throughout the First overseas ACM-L Workshop, which used to be held in Tucson, Arizona, throughout the twenty fifth foreign convention on Conceptual Modeling, ER 2006.

Included during this state of the art survey are eleven revised complete papers, conscientiously reviewed and chosen from the workshop displays. those are crowned off with four invited lectures and an introductory and motivational overview.

Taken as an entire, those papers conceal almost all the present pondering in conceptual modeling research.

The workshop in query excited by bettering the elemental figuring out of the way to version continuous studying from earlier studies and the way to catch wisdom from transitions among approach states.

Active conceptual modeling is a continuous means of describing all points of a website, its actions, and alterations from diverse views according to our wisdom and understanding.

Sample text

Atoms from A, F , E and R are called actions, facts, events, and rules respectively. For brevity, in the sequel we exclude the variables from the presentation. • Effects – We assume that an execution of a particular action in an environment in which certain facts and events hold, will modify a given fact: a causes f if p1 , . . , pn , e1 , . . , em (1) The intuitive meaning is that the execution of the action a in a in which each fact pi (i ∈ {1, . . , n}) is true and each (primitive and/or composite) event ej (j ∈ {1, .

An active rule in the context of the (ECA)2 paradigm is the proposition: validity(T/E) et if p1 , . . , pn within time/event(T1/E1) [ initiate α] ... ELSE Consumed-by-Parent = ON ec1 c1n if pc11 1 , . . , pn initiate [αc1 ] ... Subsequently: Consume Parent = ON ec2 c2n if pc21 1 , . . 1 (6) Declarative Semantics of LEAR and Hypothetical Reasoning Let DEAR denote a set of ground instances of the propositions providing the domain description. We will refer to any set of facts as a fact state, denoted as Φ, and any set of events as an event state, denoted as Σ .

Pn , e1 , . . , em a exceptionally induces e if p1 , . . , pn , e1 , . . , em a exceptionally determines f if p1 , . . , pn , e1 , . . , em In the exceptional situations, the effects of the activities are determined by the exceptional propositions and the effects of the defeasible propositions are ignored. 4 Experimental Observations Based on the benefits of the ordering of triggers execution, demonstrated in [10,23], we conducted simulation-based experiments to demonstrate the benefits of the meta-triggers when processing a reactive behavior in distributed environments.
