Today, a massive amounts of data which are often geographically distributed and owned by different organisation are being mined. As consequence, a large mount of knowledge are being produced. This causes problems of not only knowledge management but also visualization in data mining. Besides, the main aim of DDM is to exploit fully the benefit of distributed data analysis while minimising the communication. Existing DDM techniques perform partial analysis of local data at individual sites and then generate a global model by aggregating these local results. These two steps are not independent since naive approaches to local analysis may produce an incorrect and ambiguous global data model. The integrating and cooperating of these two steps need an effective knowledge management, concretely an efficient map of knowledge in order to take the advantage of mined knowledge to guide mining the data. In this paper, we present \"knowledge map\", a representation of knowledge about mined knowledge. This new approach aims to manage efficiently mined knowledge in large scale distributed platform such as Grid. This knowledge map is used to facilitate not only the visualization, evaluation of mining results but also the coordinating of local mining process and existing knowledge to increase the accuracy of final model.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122307970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main challenges is to determine which information is most crucial for analysis of a system's behaviour, and when. This paper proposes a model- based approach to self-monitoring for which structural and behavioural models of a system are described at different levels: application, subsystem, component and class level. In this approach, a system's behaviour is monitored in the context of a hierarchy of use-cases related to these levels. The structural and behavioural models are used to automatically instrument an existing distributed system. The proposed architecture of a self-monitoring engine is described as is the implementation. The models have been specified in the Ontology Web Language (OWL) and the self-monitoring (as a part of our self-management framework) has been implemented in Java. The scenario used to illustrate the approach is that of authentication for a simplified version of a distributed portal application.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122547428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the design of statistical multivariate control charts is limited to a Gaussian distribution assumption or a pre-known probability distribution model, which is hardly applicable to the computer operation data. The paper is motivated by this timely need to develop SVC (support vector clustering) based multivariate control charts, which do not require the data to have a pre-known probability distribution model. The proposed method is validated through the simulations by comparing with the popularly used statistical T2 multivariate control charts. The effectiveness of the method is also demonstrated through automatic anomaly detection of typical computer intrusions.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133171287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we address the self-maintenance of these overlay service networks by proposing the use of Virtual Service Communities (VSCs) constituted of functionally equivalent service elements with differentiated levels of QoS. These VSCs are self-organized by using a peer-to-peer (P2P) approach.

Achieved DBMS' performance depends on individual DBA skills, home-grown tuning scripts and in most cases is reactive to obvious and urgent performance problems. This paper addresses the idea of classifying, formalizing, obtaining, storing, maintaining, exchanging and individually adapting DBA expert tuning-knowledge as shared domain of understanding in the autonomic management process.

However, in many cases this information is not available. In this case, the missing context information can often either be inferred from existing knowledge using different inference approaches, or accessed from external context providers. Thereby, dealing with uncertainty is another major concern. In this paper we present a generic approach called alternative context construction trees (ACCTs) that enables the concurrent evaluation and consolidation of different alternative inference approaches, like logic rules, Bayesian networks and CoCoGraphs. In particular, we introduce a common signature structure to make those alternatives comparable in a generic way. Thereby, the approach is able to adapt dynamically to specific service requirements with respect to the accuracy of available context information. In addition, we present so called Bayesian network templates that enable a light-weight inference of high-level context information if only probabilistic knowledge about the causal interdependencies of context artifacts is available.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117200458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices can serve two important functions in Grid environment either as service consumer or as valuable service providers. However, there are a number of challenging issues in using a mobile device as service consumer in Grid systems when this fluctuating mobile environment is taken into consideration. Intermittent connectivity, bandwidth fluctuations, high response time between service request and delivery, device heterogeneity and weak security among others. Among these, this paper focuses on modeling a context aware solution to address the problem of high response time in this environment which is caused by some execution context variations. A model of an adaptation mechanism is proposed that monitors execution context of the Grid clients, it evaluates the monitored contexts and decides on what reconfiguration decision to take. The overall impact is to reduce the time between when a service request is made and when the service is delivered to mobile clients.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120957404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This causes the decline of scarce network resources such as bandwidth and energy, thus decreasing the lifetime of sensor network. Recently, mobile agent is proposed as a solution to overcome these problems. Mobile agent accounts for performing data processing and making data aggregation decisions at nodes rather than bring data back to a central processor (sink). Using this approach, redundant sensory data will be eliminated. However, carrying a huge amount of aggregated data among source nodes, using mobile agent, requires immensely planned routing. This is to avoid hastily burning source nodes energy in interest region. Towards this end, we propose a novel approach to achieve optimal routing path for mobile agent. Our proposed approach has two folds. Firstly, Dijkstra's algorithm is used to generate a complete graph to connect all source nodes. Secondly, genetic algorithm is performed on a completed graph to generate best approximated route. To demonstrate the feasibility of our approach, formal analysis and experimental results are presented.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120958243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flexibility afforded by this approach implies that autonomic feedback loops are created between the business process incarnation and its autonomous controller, which may be extended to the multiple process case where several controllers interact to form extended feedback relationships.
