Towards Common Ground in SME: An Ontology of Method Descriptors
Part 3: Method Engineering FoundationsInternational audienceThe Method Engineering (ME) community is a prolific research domain where competing Situational Method Engineering (SME) approaches have been defined and used for composing, adapting or/and configuring a method into modular constructs according to their own modularization vision. This diversity shows the richness of the ME domain but implies some drawback like unnecessary confusion for non ME expert, lack of standard & interoperability, lack of implementation tool. However, researchers are agreed that a common ground in SME is a hot matter of discussion. Assuming that the differences between SME approaches are purposeful, we propose to reach a semantic common ground on what types of core concepts constitute a method descriptor. To achieve it, an ontology-based approach is applied in SME to design an ontology of method descriptors as a domain ontology. The semantics of the six most popular SME approaches modular constructs are defined according to this ontology in order to show its usage and its relevance. Finally, usage scenarios have been sketched to show that the ontology can be the start up phase for reducing the ME drawbacks mentioned above
OntoMaven: Maven-based Ontology Development and Management of Distributed Ontology Repositories
In collaborative agile ontology development projects support for modular
reuse of ontologies from large existing remote repositories, ontology project
life cycle management, and transitive dependency management are important
needs. The Apache Maven approach has proven its success in distributed
collaborative Software Engineering by its widespread adoption. The contribution
of this paper is a new design artifact called OntoMaven. OntoMaven adopts the
Maven-based development methodology and adapts its concepts to knowledge
engineering for Maven-based ontology development and management of ontology
artifacts in distributed ontology repositories.Comment: Pre-print submission to 9th International Workshop on Semantic Web

EcoâHolonic 4.0 Circular Business Model to Conceptualize Sustainable Value Chain Towards Digital TransitionÂ
The purpose of this paper is to conceptualize a circular business model based on an Eco-Holonic Architecture, through the integration of circular economy and holonic principles. A conceptual model is developed to manage the complexity of integrating circular economy principles, digital transformation, and tools and frameworks for sustainability into business models. The proposed architecture is multilevel and multiscale in order to achieve the instantiation of the sustainable value chain in any territory. The architecture promotes the incorporation of circular economy and holonic principles into new circular business models. This integrated perspective of business model can support the design and upgrade of the manufacturing companies in their respective industrial sectors. The conceptual model proposed is based on activity theory that considers the interactions between technical and social systems and allows the mitigation of the metabolic rift that exists between natural and social metabolism. This study contributes to the existing literature on circular economy, circular business models and activity theory by considering holonic paradigm concerns, which have not been explored yet. This research also offers a unique holonic architecture of circular business model by considering different levels, relationships, dynamism and contextualization (territory) aspects
Detecting Conflicts and Inconsistencies in Web Application Requirements
Web applications evolve fast. One of the main reasons for this
evolution is that new requirements emerge and change constantly. These new
requirements are posed either by customers or they are the consequence of
usersâ feedback about the application. One of the main problems when dealing
with new requirements is their consistency in relationship with the current
version of the application. In this paper we present an effective approach for
detecting and solving inconsistencies and conflicts in web software
requirements. We first characterize the kind of inconsistencies arising in web
applications requirements and then show how to isolate them using a modeldriven
approach. With a set of examples we illustrate our approach
From Method Fragments to Method Services
In Method Engineering (ME) science, the key issue is the consideration of
information system development methods as fragments. Numerous ME approaches
have produced several definitions of method parts. Different in nature, these
fragments have nevertheless some common disadvantages: lack of implementation
tools, insufficient standardization effort, and so on. On the whole, the
observed drawbacks are related to the shortage of usage orientation. We have
proceeded to an in-depth analysis of existing method fragments within a
comparison framework in order to identify their drawbacks. We suggest
overcoming them by an improvement of the ?method service? concept. In this
paper, the method service is defined through the service paradigm applied to a
specific method fragment ? chunk. A discussion on the possibility to develop a
unique representation of method fragment completes our contribution

of the Corporate Smart Content sub-project "Smart Content Enrichment". We
present analyses of the state of the art in the fields concerning the three
working packages defined in the sub-project, which are aspect-oriented
ontology development, complex entity recognition, and semantic event pattern
mining. We compare the research approaches related to our three research
subjects and outline briefly our future work plan
Knowledge formalization in experience feedback processes : an ontology-based approach
Because of the current trend of integration and interoperability of industrial systems, their size and complexity continue to grow making it more difficult to analyze, to understand and to solve the problems that happen in their organizations. Continuous improvement methodologies are powerful tools in order to understand and to solve problems, to control the effects of changes and finally to capitalize knowledge about changes and improvements. These tools involve suitably represent knowledge relating to the concerned system. Consequently, knowledge management (KM) is an increasingly important source of competitive advantage for organizations. Particularly, the capitalization and sharing of knowledge resulting from experience feedback are elements which play an essential role in the continuous improvement of industrial activities. In this paper, the contribution deals with semantic interoperability and relates to the structuring and the formalization of an experience feedback (EF) process aiming at transforming information or understanding gained by experience into explicit knowledge. The reuse of such knowledge has proved to have significant impact on achieving themissions of companies. However, the means of describing the knowledge objects of an experience generally remain informal. Based on an experience feedback process model and conceptual graphs, this paper takes domain ontology as a framework for the clarification of explicit knowledge and know-how, the aim of which is to get lessons learned descriptions that are significant, correct and applicable
Engineering an Ontology for Autonomous Systems - The OASys Ontology
This paper describes the development of an ontology for autonomous systems, as the initial stage of a research programe on autonomous systemsâ engineering within a model-based control approach. The ontology aims at providing a uniïŹed conceptual framework for the autonomous systemsâ stakeholders, from developers to software engineers. The modular ontology contains both generic and domain-speciïŹc concepts for autonomous systems description and engineering. The ontology serves as the basis in a methodology to obtain the autonomous systemâs conceptual models. The objective is to obtain and to use these models as main input for the autonomous systemâs model-based control system
State-of-the-art on evolution and reactivity
This report starts by, in Chapter 1, outlining aspects of querying and updating resources on
the Web and on the Semantic Web, including the development of query and update languages
to be carried out within the Rewerse project.
From this outline, it becomes clear that several existing research areas and topics are of
interest for this work in Rewerse. In the remainder of this report we further present state of
the art surveys in a selection of such areas and topics. More precisely: in Chapter 2 we give
an overview of logics for reasoning about state change and updates; Chapter 3 is devoted to briefly describing existing update languages for the Web, and also for updating logic programs;
in Chapter 4 event-condition-action rules, both in the context of active database systems and
in the context of semistructured data, are surveyed; in Chapter 5 we give an overview of some relevant rule-based agents frameworks
