Security vulnerabilities play an increasing role within dependability procedures for information systems. However, traditional vulnerability models present several general shortcomings when matched with today requirements. To overcome these limits, we propose a vulnerability ontology based on three main enhancements: deeper integration with system asset ontology, better modelling of cause-effect relationships,...
To improve sharing and reusability of designing knowledge in domestic enterprises, a proposal of sharing of knowledge based on functional ontology was proposed. By using bases of knowledge of functional ontology, the mapping of structure-to-function has been realized. On basis of comprehensively understanding original functional model, through changing way of function achievement to obtain new functional...
When there are many possible personalization strategies, it is important to select the most appropriate of them according to the specificities of the course. In this context, rises the contribution of this work, which is the analysis of learning objects as well as the metadata describing them for the selection of appropriate personalization strategy.
Assessment plays an essential role in the educational activity, not only to verify the knowledge acquisition of learners, but also as a motivation factor. In this paper we consider the IMS/QTI specification. We first propose a formalization of the question structure in his specification based on ontology, representing its information model. Then we enhance this specification by adding new types of...
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...
Nowadays, learners use not only PC but also their own mobile devices for e-learning. For this, author should make various versions of learning contents for device specification and learning management system provides suitable contents for device specification. To select suitable contents for learner's devices, previous researches propose contents selection method that describe suitability score for...
With the growing usage of ontologies, different ontologies are constructed in the same domain from different specialist's knowledge structures, this results in ontology heterogeneity, and the interoperability of ontologies is seriously blocked by ontology heterogeneity. It is known that Ontology Merging is an effective approach to solve this problem, so a novel method FCA-OntMerge for ontology merging...
We describe a framework for personalized context aware search of ontology-based tagged data. As more services are offered on the Web, it is becoming increasingly difficult for users to manage their content online. We propose a framework that performs context-aware search of tagged data using a tag ontology that includes context information in addition to tagged keywords in order to present more meaningful...
We propose an integrated framework that manages changes in long term composed services. The main procedure of change reaction is presented. One of the most challenging research issues of change management is how to automate the process of change reaction. To address this issue, we propose a semantic support, which centers around a tree-structured Web service ontology. The ontology is expected to provide...
Given the large amount of existing services and the diversified needs nowadays, it is time-consuming for end-users to find appropriate services. To help end-users obtain their desired services, context-aware systems provide a promising way to automatically search and recommend services using a user's context. However, existing context-aware techniques have limited support for dynamic adaption to newly...
Web service composition is to integrate existing web services to provide a compound service which satisfies specified requirement. However, traditional web service compositions fail to provide different compound services under various scenarios. In this paper, we propose an approach to compose services with context. A context ontology is defined to describe the scenario for user. An abstract service...
Map services help people find places they wish to visit. Users input the target address and the system returns that location on a map, with additional information such as nearby points of interest, directions to the location, etc. However, these applications mainly focus on general knowledge, failing to provide personalized information that may help users find/identify a place faster. In this paper,...
One issue for context-aware applications is to identify without delay situations requiring reactions. The identification of these situations is computed from both dynamic context information and domain specific knowledge. This identification is the output of a process involving context interpretation, aggregation and deduction. In smart environments, these treatments have to be efficient since they...
An intelligent content adaptation system taking semantic adaptation method is built to provide good personalized service for user. Compared with some website using web mining and collaborative Filtering technology, in this system, the intelligence comes from the knowledge service providing by CBKMF(ontology-Cloud based knowledge manage framework), in which knowledge modeling, managing, data-mining...
Recently the use of ontologies is becoming more widly spread, however building ontologies is remains a challenging issue, especially for maritime domain, which has no structural resources in existence. In this paper, we propose a method that is based on Formal Concept Analysis(FCA) and illustrate this method on some examples. Formal concept analysis is a theory of data analysis which identifies conceptual...
Since 1960, lots of AI researchers work on intelligent and reactive architectures able to manage multiple events and act in the environment. This issue is also part of Robotics domain. A decision process must be implemented in the robot brain to accomplish the multimodal interaction with human in human environment. In this article, we present a semantic agents architecture giving the robot the ability...
Ontologies is playing an increasingly important role in knowledge management and the Semantic Web. The tourism information ontology is becoming a core research field in the realm of information retrieval. An ontology construction method based on Formal Concept Analysis (FCA) to extract domain ontology from unstructured text documents is proposed. Under the framework of our ontology construction method,...
There have been attempts to offer “toolkits” or software to enable ease of entry into pedagogic design and support non-specialists in engaging with learning theories. Despite the efforts, existing e-learning systems and authoring tools have several limitations in respect of support provided and cannot accommodate the needs of teachers who increasingly look for more intelligent services and support...
Platforms expand maintenance systems from centralized systems into e-maintenance platforms integrating various cooperative distributed systems and maintenance applications. This phenomenon allowed an evolution in services offered to maintenance actors by integrating more intelligent applications, providing decision support and facilitating the access to needed data. To manage this evolution, e-maintenance...
Much research in the use of concept lattices for knowledge discovery and data mining has occurred in the past several years. Various approaches have also been proposed to create fuzzy formal contexts and to transform these into fuzzy concept lattices. This paper first briefly reviews concept lattices and then presents several approaches to creating fuzzy concept lattices. One of these approaches is...
