Non-functional Parameters as First Class Citizens in Service Description and Matchmaking - An Integrated Approach
نویسندگان
چکیده
Automatic discovery and invocation of services will only be accepted in practise, if the non-functional, especially QoS, parameters are taken into consideration during matchmaking. In this paper we present how this can be achieved. As an example, we use the DIANE framework and explain how the concepts developed there can be extended to easily accommodate non-functional aspects. Thereby, these aspects become first class citizens given the same importance as functional requirements during service selection.

An Approach to Semantic Matching of Web Services
One of the challenging problems that Web service technology faces is the ability to effectively discover services based on their capabilities. An approach is proposed to tackle this problem in the context of description logics. The semantic information of a Web service can be described with three factors: functional capabilities, action and non-functional attributes. We formalize these three fa...
متن کاملRe-ranking Web Service Search Results Under Diverse User Preferences
Web service discovery aims at finding available services that match a given service description. This involves mainly the matchmaking of the functional parameters of the services, whereas non-functional attributes can also be considered and aggregated in the matching score of a candidate service as additional criteria for ranking the results. In this paper, we address the problem of re-ranking ...
متن کاملImproving the Performance of Semantic Web Services Discovery: Shortest Path based Approach
Service discovery is the process of retrieving the service most similar to the query based on the description of functional and/or non-functional semantics. The original algorithm used in literature was proposed by Paolucci et al., 2002. Some research works, propose an extension or an improvement of this algorithm to correct the matchmaking used. In this paper we present an algorithm of matchma...
متن کاملSemantic Matchmaking as Non-Monotonic Reasoning: A Description Logic Approach
Matchmaking arises when supply and demand meet in an electronic marketplace, or when agents search for a web service to perform some task, or even when recruiting agencies match curricula and job profiles. In such open environments, the objective of a matchmaking process is to discover best available offers to a given request. We address the problem of matchmaking from a knowledge representatio...
متن کاملMODELING RISK OF LOSING A CUSTOMER IN A TWO-ECHELON SUPPLY CHAIN FACING AN INTEGRATED COMPETITOR: A GAME THEORY APPROACH
In a competitive market, customer decision is made to maximize his utility. It can be assumed that risk of losing a supply chain’s customer can be defined based on products utility from customer point of view. This paper takes account of product price and service level as competition criteria. The proposed model is based on non-cooperative game theory, for one-manufacturer and one-retailer supp...
