A few e-Learning platforms propose a solution for ubiquity and context aware adaptability. We decided to propose a solution with meta modeling approach based on previous related works. We used a concrete software engineering industrial product that was promoted by French Government.
In this paper we present a general framework to describe a trace-based learner modelling process. This framework includes three knowledge models: the first model is an explicit representation of observations about learner's interactions with a TEL-system, the second model describes the structure and elements describing the Learner Model and the last model describes the main knowledge elements types...
In this paper, a method to adapt the fuzzy sets that models the ”coarseness” texture property according to different coarse-fine perceptions is proposed. The membership functions associated to these fuzzy sets are obtained on the basis of the human assessments given by a pool, that represent the average coarse-fine perception degree. In the proposed method, the user's particular perception about coarseness-fineness...
Document processing has the characteristics of MVC. By using MVC pattern, a document processing system can be divided into the roles of model, view and controller. This article proposes a framework of office document processing based on MVC and XForms and discusses the key technologies of on-line office document processing system, as well as how to recognize and separate model, view and controller...
Student model is an essential component in any adaptive learning environment. Various student modelling approaches have been suggested in the literature that focus on learners' competencies, preferences and other personal attributes. However, there is a lack of a comprehensive student model that combines various aspects of student modelling while also considering the aspects of location and context...
Context-awareness and adaptability are important and desirable properties of service-based processes designed to provide personalized services. Most of the existing approaches focus on the adaptation at the process instance level which involves extending the standard Business Process Execution Language (BPEL) and its engine or creating their own process languages (e.g. However, the approach proposed...
Most work on adaptive workflows offers insufficient flexibility to enforce complex policies regarding dynamic, evolvable and robust workflows. In addition, many proposed approaches require customized workflow engines. This paper presents a portable framework for realistic enforcement of dynamic adaptation policies in business processes. The framework is based on the Model-View-Controller (MVC) pattern,...
This paper proposes a method of using fuzzy neural network into the security access control model based on the Trust-based access control model (TrustBAC). Under the circumstance of users' confidence changing with the context information, in order to solve the problem of dynamic access control and authorization, this paper provides a new attempt by building a reasonable fuzzy neural network topology...
We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment. Due to the resource limitations of MIDs,...
In the last years, autonomous and adaptive processes have became more and more important. Even business processes are more complex today. The more complex a system becomes, the more difficult it is to handle changed requirements. This increases the need for adaptation abilities of workflows. In these new workflow systems, autonomy would have great impact regarding the possible usability of such workflows...
This paper describes the development of an emotional agent who affects the attitude of students towards learning and helps them overcome learning obstacles. Face to face communication is simulated through synthetic characters that have the potential to portray emotions by recording user's emotions and reacting accordingly. This form of communication might offer new approaches in the educational process...
This paper presents the results of our innovative approach for the realization of a model driven development framework for modeling context-aware adaptive learning activities within Context-aware and adaptive learning environments. Its core element consists of a domain specific visual modeling language called CAAML (Context-aware Adaptive Activities Modeling Language). After, we present the developed...
Within an educational context, adaptation could improve the learning's quality. Many researches are done in the learning-situations adaptation field. The Educational Modeling Languages (EML) and tools provided currently to the teacher for a learning design, as preexistent means in our sense, remain useless by practitioners. In our work we aim to support the practitioner teacher to design and adapt...
In this article we present an infrastructure for creating mash up visual representations of the user profile that combines data from different sources. We explored this approach in the context of Life Long Learning, where different platforms or services are often used to support the learning process. The system is highly configurable and adaptive: data sources, data aggregations, and visualizations...
This paper presents an architecture to transform an existent e-learning environment in a situation-aware environment, bringing the concepts of context awareness, situation and scenario to this environment. For a specific scenario, ontologies may be employed to represent the knowledge that the system has on the domain to be studied, on the situation where the study is being performed and also based...
In this article we illustrate and discuss a techno-centric aspect of re-engineering realized on an existent TEL system: the Apprenticeship Electronic Booklet. Although this system has been designed with end-users following a participatory process, the first version had also been found too rigid in regard to the roles management and to the underlying academic structures. In order to improve this TEL...
A set of new types of assessment is required for learning management systems (LMSs), and there is a need for a way to assess lifelong adaptive competencies. Proposed solutions to these problems need to preserve the interoperability, reusability, efficiency and abstract modeling already present in LMSs. This paper introduces a set of software tools for an author assessment package on the LMS Mooddle...
In order for the intelligent assistant systems to provide users with timely and appropriate assistances, most of them focus on what is considered to be the "rational" aspect of the user behaviors. However, since human desire is the fundamental driving force of human behaviors, without including users' desires, the system cannot provide most appropriate responses. We propose a hierarchical...
Intelligent Environments depend on their capability to understand and anticipate user's habits and needs. Therefore, learning user's common behaviours becomes an important step towards allowing an environment to provide such personalized services. Due to the complexity of the entire learning system, this paper will focus on the automatic discovering of models of user's behaviours. Discovering the...
In this paper, we are interested in content oriented XML information retrieval whose aim is to retrieve not a list of relevant documents, but only fragments of document (XML element) relevant to the user information need. Retrieved XML elements must not only contain relevant information but also be at good level of granularity. The coexistence of content and structural information in XML documents...
