Given that EA provides support for the IT environment by simulating alignment between dynamic business architectures, heterogeneous application systems and incongruent technologies, the need to ensure validation of conceptualized EA models has become also critical. As a relatively new discipline, its disparate and widespread methodologies makes it even more challenging to adopt a generic approach in which models can be verified sequel to the unavailability of unified EA modelling languages able to describe a wide range of Information Technology domains. This paper seeks to present an approach for addressing this challenge through the use of ontologies and queries based on constraints specified in the model's motivation taxonomy. The paper is experimental research-based and grounds its hypothesis on initial model created using the ArchiMate modelling language. By transforming its conceptual metamodel into a model instance, a process which can be achieved irrespective of the modeling language used in the design of the EA, it represents extracted triples as resource description framework schema (RDFS) by mapping the model artefacts directly into classes and slots using a more conventional web ontology language. The generated RDF is then queried using Protocol and RDF Query Language (SPARQL) adopting the Behavior Driven Development (BDD) concept. A case study of the Student Internship Program (SIP) is deployed to translate information from business needs to IT solutions encapsulating a view of abstraction of the EA. The paper also proposes an implementation of the approach using an open source platform that allows construction of domain models and knowledge-based applications with ontologies and is a contribution towards effective validation of EA through taxonomy decomposition, systematic generation of testable EA artifacts, creation of structural triples of model elements and alignment of motivational goals to business behavior specifications.","PeriodicalId":110586,"journal":{"name":"2013 3rd International Symposium ISKO-Maghreb","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127859150","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 the context of modeling the EA layer is a point of view as a strategic, business, technical point of view etc. In addition, the information system (I.S) is not just a technical challenge, focused on information and IT support systems. On the contrary, everything indicates that the key issues within the organization and the human factor in business as well as their competence. So taking into account the changes in the organization is critical to the success of urbanization projects. Thus, organization models have been developed in the context of enterprise architecture (EA). These models aim to structure a holistic view of the enterprise. However, a semantic deficit was identified by several researches in these models. So, several studies have investigated to solve this problem by proposing ontologies as a semantic enrichment tool. Based on these works we built an ontology that aims to support the process of change in an UIS approach. Thus we present in this paper a first part summarizes the different ontologies developed for the company and in the second part we present a modular ontology oriented competence exploitable in the context of UISI. Then in the end we present the technical way to use this ontology.","PeriodicalId":110586,"journal":{"name":"2013 3rd International Symposium ISKO-Maghreb","volume":"79 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114322473","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, we present a Bayesian network model that captures the relationships between this information to evaluate the relevance as matching relationships between documents, user's interest and query concepts.

The proposed approach to transforming data, when transferring them between individual applications or services of the system, is to convert input messages into output messages using an intermediate canonical representation of the data via rules that map the source model to the canonical one, and the canonical model to the target. Since the canonical model of a subject area serves a technical important task and is not intended for human use, it may be generated automatically instead of manually and designed `from scratch', as a `union' of models used in the various application parts of the system. Subject area models of the application parts being integrated may be written using different formalisms, and yet another formalism may be used for the canonical model, so that a mechanism is required to automatically capture various concepts expressed in various formal systems. In the present paper we focus on developing such a mechanism, based on the automatic generation of a (somewhat simplified) representation of the most important kinds of entities in the canonical model.","PeriodicalId":110586,"journal":{"name":"2013 3rd International Symposium ISKO-Maghreb","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127837468","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}
