Threat intelligence is the provision of evidence-based knowledge about existing or potential threats. Benefits of threat intelligence include improved efficiency and effectiveness in security operations in terms of detective and preventive capabilities. Successful threat intelligence within the cyber domain demands a knowledge base of threat information and an expressive way to represent this knowledge...
The purpose of this paper is to define architecture for organizational memory systems in institutions of higher education. The aim arose from the identified problem, where the constructions of knowledge management systems are being handled in a rapid prototyping approach. In the rapid prototyping approach the acquired knowledge was encoded directly into an iteratively developed computer system and...
Advanced mobile devices increasingly provide innovative services and applications that can be accessed anywhere and anytime. The actual challenge is to take into account the dynamically changing conditions of the heterogeneous resources (equipments, data sources, services, etc) required for providing in ubiquitous environments an optimized, self-adaptive and personalized task management according...
Currently most present web-based course still organized knowledge in accordance with sections. In view of the existing problems of the above knowledge organization form, this paper takes the curriculum of computer organization as an example to discuss ontology-based knowledge representation. In the extraction of concepts and their relationships, this paper not only borrows ideas from WorldNet, a quite...
Our research revolves around collaborative platforms entirely dedicated to research activities for several scientific organizations. Here, researchers from different domains interact and exchange information using our platforms as the common ground involving new concepts, methods and services to encourage collaborative work for their research activities. The work is based on the co-operation and collaboration...
Potential Failure Modes and Effects Analysis in Manufacturing and Assembly Processes (PFMEA) is an important preventive method for quality assurance, and through it the decisions based on the severity levels and probabilities of occurrences and detection of the failure modes can be planned and prioritized, seeking to improve the quality of the manufactured products. This activity generates a valuable...
To develop the Practice Teaching System of Information Management Training (PTSIMT), this paper presents the method based on agent and Ontology to design the architecture, which consists of four layers with different functions. The Agency is in charge of giving support to the PTSIMT processes, which has three types. In this method, Ontology is used to represent the knowledge in knowledge base and...
According to the temporal and dynamic characteristics of emergency knowledge, the paper, on the basis of the traditional knowledge representation model, proposes a model of emergency knowledge representation, which is “emergency conception ontology + temporal logic + process template”, to solve the problem of emergency knowledge digitization. After that, the paper constructs the framework of intelligent...
In recent years, the combination of case-based reasoning (CBR) and domain knowledge has become a hotspot in CBR field. Different knowledge representation ways bring about different influences of CBR system performance. This paper makes a summarization and an analysis of deficiencies in integration between traditional knowledge representation and CBR, based on which it proposes a scalable case representation...
After the introduction of knowledge management, ontologies, intelligent tutoring systems, and the relationships among them, a model of ontology-based knowledge management in intelligent tutoring systems is presented in this paper. It consists of knowledge representation, organization and acquisition module, knowledge distribution module, and knowledge maintainess module. The knowledge representation,...
The formulation of conceptual relations is the most important part in building a conceptual representation; it is also the most demanding. Developing a framework of conceptual relations to support users in this task not only reduces the cognitive loading associated with it but also reduces the variability of expressions, a necessary condition for sharing and exchanging conceptual representations....
The model presented in this paper is the main result of an on-going national science foundation project of china, called emergency-driven virtual organization (EDVO), which aims at integrating and scheduling heterogeneous, distributed resources from multi-domains, as well as sharing knowledge among them. Therefore, knowledge representation and sharing among the participating organizations become critical...
Technology foresight is an emergent tool for technology policy making both at national and business levels. This research takes advantage of the knowledge representation technique known as ontology to categorize the things that are assumed to exist in a specific technology domain. Technology foresight model is developed in this paper without any detail about the embedded concepts. Each country can...
The model presented in this paper is the main result of an on-going national science foundation project of China, called emergency-driven virtual organization (EDVO), which aims at building and developing an innovative software infrastructure (software, models, services, etc.) for supporting collaborative work of events handling in emergency/disaster scenarios. In such scenarios, different government's...
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure...
Agent-based computing environments provide the capability to establish an enterprise of autonomous agents that collaborate and share information on common interests. Discovery of new data can alert users to changes in the information environment of importance to them. The goal of this research is to define an agent environment that models an organization's tacit knowledge. This document proposes a...
Acousmatic works are defined at INA-GRM as pure recorded music that is without live instrument or electronic interaction. Usually, the archive of those pieces consist on a single final tape and its security copies, nowadays a single digital file. In the framework of the CASPAR project, it appears to us that it is very important to archive more elements (variants, source elements, notes, etc.) to perform...
Business process models are an important tool in understanding and improving the efficiency of a business and in the design of information systems. Recent work has evaluated business process modelling languages against upper-level ontologies on the assumption that these ontologies are adequate representations of the general process domain. In this paper, we present a method to test this assumption...
Statistical graphs are ubiquitous mechanisms for data visualization such that most, if not all, enterprises communicate information through them. However, many graphs are stored as unstructured images or proprietary binary objects, making them difficult to work with beyond the reports in which they are embedded. While graphs can be mapped to more common XML representations, these lack expressive semantics...
Our research revolves around a platform called ToxNuc-E entirely dedicated to the research activities in studying effects of nuclear toxicology on plants and animals. Here, researchers from different domains interact and exchange information using our platform as the common ground involving new concepts, methods and services to encourage collaborative work for their research activities. The work is...
