However, technological support for the efficient organization of providing and consuming services across corporate boundaries is still not mature enough to allow for a large-scale adoption particularly among small-and medium-sized enterprises. In this article, we propose and evaluate different strategies with regard to architectures supporting the organization of service interconnections: In case of rather standardized and stable business relationships and interactions, a central service orchestration architecture, a hybrid orchestration approach with hub support and finally a fully decentralized peer-to-peer solution without any central control entity are proposed and compared in detail. In cases where business processes are highly complex, variable and dependent on situational factors, we propose a more implicit, declarative service orchestration methodology which builds upon Event-Driven Architectures (EDAs). For the different architectural strategies, we provide real-world exemplary implementations to prove their applicability and to investigate their strengths and weaknesses.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127354141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to be developed in an optimal way, such applications need appropriate middleware services. This paper introduces Pervaho, an integrated middleware aimed specifically for supporting the development and testing of mobile context-aware applications. To illustrate the use of Pervaho, we walk through the development of a concrete mobile context-aware application and show how it can be elegantly built on top of Pervaho's location-based publish/subscribe service. We also illustrate how a specialized mobility testing tool significantly simplifies the process of testing proximity-based semantics. We then present the implementation of Pervaho, which is based on a set of communication protocols geared at mesh networks. Finally, we provide a performance analysis of our implementation.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126268002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper an e-negotiation framework for building complex negotiation systems with emphasis on their automation is presented. A novel approach for dynamically adapted e-negotiations, that exploits ontologies, semantic Web services, software agent platforms, service oriented architecture and knowledge-bases is described. The relationship between negotiation protocol, process and strategy specification is examined and a way of describing and representing them using a hybrid approach that integrates rules and workflow diagrams is introduced.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124955442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SOA promotes the use of loosely coupled services to automate business processes. The automation of business processes raises several challenges for enterprises. One of those challenges relates to the maintenance of business processes, more precisely how to facilitate changes within existing business processes, possibly even at run-time. Furthermore, changing a collaborative business process can have an impact on the contract specified between the parties involved. Thus, a business process may need to adapt to meet a new contract. Some approaches propose solutions to support business process adaptability; however, they do not handle adaptability in the context of multi-partner collaborative business processes. In this paper, we propose a new approach to support adaptability for such collaborative processes. This approach uses a protocol, called Change Protocol for Collaboration (CPC), for managing the changes that can have incidence on the contract.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124272677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first two provide descriptions similar to those found in typical programming languages, namely, syntactical description of service interface and operational description of service behavior. In this paper, we show how Web services descriptions can be extended with simple declarative behavior specification, using a form of regular expressions. We explain the relationships between such specifications and WS-BPEL abstract processes. We also describe how a concrete, thus executable, WS-BPEL process can be shown to satisfy its associated abstract specification, using the SPIN model-checker.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121655870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vachon","doi":"10.1109/MCETECH.2008.33","DOIUrl":"https://doi.org/10.1109/MCETECH.2008.33","url":null,"abstract":"As one can expect, members of a common market are likely to work in quite different domains and use different kinds of schemas to describe their own business data. An ideal world would allow such heterogeneous data to be integrated into some (concrete or virtual) business data repository. It seems illusory to think that all members joining a common marketplace can directly provide data adhering to some predefined federative data scheme (e.g. standard ontology). More flexibility is usually required. Realistically, the integration of a new data source requires a mapping step allowing to compute semantic equivalences between the various schema concepts to be merged. This task can be alleviated by the use of semi-automatic mapping tools which evaluate semantic similarities between concepts. Most of these mapping systems currently rely on linguistic matching and are not so efficient when dealing with highly heterogeneous data sources. Some of them refer to general purpose dictionaries not taking into account the specificity of data sources' domain. To better cope with data source heterogeneity, this article presents INDIGO, a system which can compute semantic matching by taking into account data sources' context. The distinctive feature of INDIGO is to enrich data sources with semantic information extracted from their individual development artifacts. Thanks to this enrichment step, INDIGO can then compute a more accurate mapping between the two data sources thus enhanced. INDIGO was experimented on two case studies presented in this paper. INDIGO's performances are also compared to the results of three matching systems often cited in this research domain.","PeriodicalId":299458,"journal":{"name":"2008 International MCETECH Conference on e-Technologies (mcetech 2008)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134356379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
