“…Various methods have been proposed for service discovery and composition. Graph-Based approach proposes a modeling language called interface automata as the low-level construct [6]. Two categories of service composition include syntactic and semantic composition.…”

Context-awareness has become the key attribute for empowering our day-to-day systems and services to be pragmatic and distinctly powerful. Purpose-specific and generic systems, be it physical, mechanical, electrical, electronics, or computing systems are getting bestowed with enabling smartness in order to be cognitively adaptive in their actions and reactions. That is, based on the changing contexts, systems are internally as well as externally equipped to be smart in their operations, offerings and outputs. However precisely understanding the evolving contexts and feeding them into systems dynamically in time to empower them to exhibit desirable and delectable behavior are not an easy task. Thus mathematicians and computer scientists are in unison in exploring and expounding a variety of viable and venerable mechanisms and means in order to streamline and simplify the process of context-awareness.In this paper, we have zeroed down on the unique capabilities of service automata in composing atomic and discrete actions into context information on which the designated system trusts and forges ahead in accomplishing what is initially intended. We have come out with a use case in a smarter hospital environment and proved that how service automata come handy in fulfilling the intrinsic needs of contextawareness.

“…The refined meta-composition is no more a sub-network of N. It is still an interaction network, but with slightly modified meta-operations. Compared to the meta-composition as found at the previous step, while m 7 is removed from meta-operations, o 1 '' and o 6 ' are removed from the underlying operations of their respective meta-operations m 1 and m 6. Given the refined meta-composition resulting from the previous step, Procedure 2 is used to instantiate this refined meta-composition. As shown in Figure 3 …”

“…Composition search is done by SQL statements. In [6], a breadth first search algorithm is used to search for compositions in a semantic network of parameters. In [7], the information on link analysis of a semantic Web service interaction network is used to guide the A* shortest path search algorithm that probe the Web service space.…”

“…The execution sequence is represented as a dependency graph G = (V, E) as in [11]. The set V of nodes represents a component to be executed, while the edge E represents a pairwise execution dependency between two components.…”

“…We represent each component via an interface automaton, thus [11] Two interface automata P and Q are composable if their execution actions are disjoint, except that an input action of one may coincide with an output action of the other. Hence the necessary condition for two components to possess composition dependency, is that their respective interface automata be composable.…”
