In modern data analysis, knowledge can be discovered from data tables and is usually represented by some rules. However the knowledge is useful for a human user only when he can understand the meaning of the rules. This is called the interpretability problem of intelligent data analysis. The solution of the problem depends on the selection of the rule representation language. A good representation language should have clear semantics so that a rule can be effectively validated with respect to the given data tables. In this regard, logic is one of the best choices. Starting from reviewing the decision logic for data tables, we subsequently generalize it to fuzzy and possibilistic decision logics. The rules are then viewed as the implications between well-formed formulas of these logics and their semantics with respect to precise or uncertain data tables are presented. The validity, support, and confidence of a rule are also rigorously defined in the framework.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

Huge benefits regarding the reduction of time-to-markets, reduction of effort, and quality improvement have been reported as a result of adopting a product line approach. Since a product line program involves major investments, considerable risks are associated with it. Thus, it is important to evaluate at the start of a product line project, i.e., before the major investments are performed, its potential benefits and risks. In this paper we describe an approach that allows to identify the benefits and risks in a systematic manner, thus enabling the early development of risk-avoiding measures. As opposed to other techniques our approach supports the identification of subdomains that are particular appropriate for systematic reuse and by means of the detailed evaluation enables trade-off decisions on where to invest for reuse.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

Nowadays, policy-based management addresses this need, but such management is not enough either network managers often deal with QoS tasks that cannot be performed using only policy-based management This paper describes six important QoS management-related tasks (QoS installation, operation maintenance, discovery, monitoring, analysis and visualization) and shows solutions that can help managers proceed with these tasks. However, these solutions are independent from each other, leading to a scenario where integration is difficult. To solve this lack of integration, QAME (QoS-aware management environment) has been developed, which provides support to allow the execution of the defined QoS tasks in an integrated fashion.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

In practice, UML fails due to its lack of accuracy. Scenarios in UML, a.k.a. Sequence Diagrams, are natural tools for modeling object interactions and collaborations. Unfortunately, there is no support to deal with combinatory explosion, no support to arrange scenarios in independent packages or to express formal relations between scenarios. Large complex applications and their specification however generate such expectations, and more generally, scalability issues impose a component-based software development. By introducing scenario invariants and contracts in conformance with Class Diagrams, we provide here an original design method. It is illustrated by means of a concrete large-scale networking application. Since implementation is also highlighted, we sketch how the UML models can be derived into components as for instance Enterprise Java Beans (EJBs).","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

In the first approach, a new common interface is constructed at runtime which allows the functionality of two or more components to be accessed from a single entity while the service components themselves remain distinct and potentially distributed within in a network. In the second approach, a new composite service is formed where all of the functionality of the service components is housed within a single new service. In the third approach, a new composite service is formed where all the functionality of the service components is extracted and re-assembled into the body of a single new service. The paper describes the design of an infrastructure to support the runtime creation of composite services. An application to create user-defined security associations dynamically and deploy them between any two points in the Internet is presented to exemplify the need for dynamic service composition techniques. Some other potential applications in e-commerce and software provisioning are also discussed.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

In view of the nature of clustering market basket data, we devise in this paper a novel measurement, called the small-large (abbreviated as SL) ratio, and utilize this ratio to perform the clustering. With this SL ratio measurement, we develop an efficient clustering algorithm for data items to minimize the SL ratio in each group. The proposed algorithm not only incurs an execution time that is significantly smaller than that by prior work but also leads to the clustering results of very good quality.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

However, while the rationales and mechanisms employed are dramatically different, the relative strengths and weaknesses of these approaches are unknown, making it difficult for a practitioner to choose an appropriate approach for the problem at hand. In this paper, we describe in detail three representative approaches, which are all practicable, and present a quantitative comparison using our experimental distributed object computing platform. Among these three approaches, namely, JavaSpaces based, request redirection based, and fuzzy decision based, we find that the fuzzy decision based algorithm outperforms the other two considerably.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

As a cost-effective facility for supporting TMO-structured distributed RT programming, a middleware architecture that can be adapted to various well-established commercial software/hardware platforms has been established. It has been named the TMO support middleware (TMOSM). In this paper, an adaptation of TMOSM to the Windows CE platform is discussed.

Such attacks in traditional networking are difficult to recognize and to handle. An active infrastructure that can dynamically respond to event-triggered requests can deal better with recognition and handling of DoS attacks. We present a DoS attack response system architecture and we demonstrate via an application scenario its dynamicity and flexibility in dealing with this kind of attack. The approach is based on agent-enabled active programmable infrastructures and makes heavy use of mobile agent technology in order to asynchronously respond to critical situations. Finally, we comment on the pros and cons of our approach and discuss future directions that could be followed.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.
