Land use and land cover (LULC) can usually indicate the change of the eco-environment for one area. In this study, a knowledge based decision tree classification system based on the spectrums knowledge of ground objects and their spatial knowledge was developed for the research area, the southeast coastal area in Fujian province, China. The knowledge based classification system was built by using...
This paper presents definitions of a fuzzy knowledge system and fuzzy logic formulae. Information entropies of the fuzzy logic formulae and information entropies of fuzzy rules of the fuzzy knowledge system are described, and relative properties of these definitions are discussed. And then, classification and evaluation of the siso fuzzy system are given based on the information entropy. Finally,...
This paper try to design structure of IT Service system Design and Management of web-based learning platforms. The frame of IT service system is including analysis of users' requirement, IT service management system. IT Service Management System Foundation and IT Service organization.
This paper try to design structure of IT Service system Design and Management of Educational Information System in University The frame of IT service system is including analysis of users' requirement, IT service management system, IT Service Management System Foundation and IT Service organization. Help desk becomes only interface for all levels of users according to their individual demands. Though...
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...
This paper tries to design structure of Web-Based Service Management of Distributed Learning (WSMDL). The structure integrating IT service and Educational Auxiliary System service flow. Help desk becomes only interface for all levels of users according to their individual demands. Though analysis of service events and userpsilas feedback in service flow, it also provides the decision-making to improve...
Applying grid technology to ITSM of e-learning will greatly improve the reliability of e-learning. There are three levels in mechanism of grid-based ITSM mechanism: Hardware and the resource database, grid server system and userspsila portal. The appliance of the mechanism in an university is proven itpsilas efficiency.
The model of city E-service with grid based on new growth theory will have the long-time life time according to the theory of endogenous growth, learning-by-doing and Knowledge spillovers theory. Learning by doing theory makes the model more efficiency. Knowledge spillovers theory makes the entourage organization grow up together. The grid computing theory gives the city platform more power. The grid...
With an increasing complexity of business processes, self-healing capability is becoming an important issue in order to support robust service flow execution. In this paper, a dynamic self-healing mechanism is proposed, which can dynamically identify suitable alternatives and replace faulty services such that a service flow can be performed successfully despite of unexpected exceptions. This mechanism...
Globalization leads to an efficient new business paradigm generally known as collaborative virtual enterprise (CVE) which demands flexible service orchestration and robust workflow execution. As two major service orchestration strategies, OWL-S and BPEL have their own strength and deficiencies. To meet the challenge in CVE, in this paper, we propose a workflow execution system (WES) that takes advantage...
Self-healing in workflow is becoming prominent because of the increasing software complexity. In order to support robust workflow execution, in this paper, we propose a self-healing mechanism to replace the faulty service dynamically. It is based on our previous research work -workflow execution system (WES). The OWLS2BPEL Mapper in WES is further enhanced to embed the self-healing mechanism into...
To induce rules from numerical data by rough sets, there are two kinds of methods. One is to discretize the original data and then apply the crisp rough sets models. Here the rough sets models which can only deal with the nominal data are called crisp rough sets models. The other is to fuzzify the original data and then apply fuzzy rough sets models. There are some problems on both of these methods...
