Such databases are at the heart of e-mail managers, flight booking, and other e-commerce systems. Key problems associated with such searches are the structure and interface of the search query. The traditional solution for these problems involves the use of a separate text field for each element of the query structure. However, the requirement to support ever increasing numbers of inexperienced users, who require an efficient and user-friendly interface, is not met by the traditional solution. We present natural search queries (NSQ), a simple and intuitive approach to the search of structured information. Our solution combines the ideas of natural language database interfaces and operator based search; queries, in simplified and intuitive natural language, are entered into a single text field. It is a front-end search interface oriented towards the common user. Our aim is to allow as much freedom in formulating queries as possible, while interpreting such queries as accurately as possible, to automatically extract the elements of the query structure. In our project, we address the problem of e-mail databases, but the results may be applicable to other databases oriented towards consumer users. The paper introduces the grammar of natural search queries and probabilistic methods for recognizing the query structure (i.e., parsing, and hidden Markov model). In addition, we demonstrate a complete implementation of a system for processing NSQs and presenting retrieved messages. A specific subproblem that was addressed is the deterministic recognition of natural date constraints. Tests show promising results in processing a broad range of natural search queries.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"51 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":"123920485","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}

Policies can be used within the autonomic management elements of the system to provide action directives to adjust application or system tuning parameters in order to meet operational requirements. Policy specification is frequently component-based, that is, focused on the operational requirements of a particular system component, e.g., a Web server or a database. In multi-component systems, such as e-commerce systems, multiple components may co-exist on a single server and cooperate to deliver a set of services. It is reasonable to expect that each component would have its own set of associated policies and that, in turn, the autonomic management system could identify actions to take per component. However, these independent sets of policies may possibly yield multiple directives from which the autonomic manager must select one or more appropriate actions. In this work, we look at an approach which tries to select one or more actions based on previous behavior. Previous decisions are captured in the form of states and transitions which in turn are used to try to find good sequences of actions. We describe how the states are formed and actions identified. We describe the implementation of an autonomic manager using this approach and report on the experience in managing a dynamic Web server.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"17 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":"125246497","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}

On a computational Grid, for instance, it is common to notice a high variation on resource availability, node instability, variations on load distribution, and heterogeneity of computational devices and network technology. The Adapta framework is a reflective middleware that provides the means to develop self-adaptive component-based distributed applications, separating the business code from the one responsible for adaptation. Adapta also provides a runtime execution environment that monitors computational resources and notifies application components about the occurrence of important events that should trigger reconfiguration actions. Adapta provides a XML based reconfiguration language that defines how the application must adapt in response to environmental changes. Statements of the reconfiguration language can also be applied at runtime, which allows to dynamically change the reconfiguration mechanism itself. This paper describes Adapta architecture, implementation, and evaluation through a concrete case study, where a grid infrastructure is augmented for incorporating autonomic mechanisms towards a self-healing and self-optimization infrastructure.","PeriodicalId":288478,"journal":{"name":"Third International Conference on Autonomic and Autonomous Systems (ICAS'07)","volume":"40 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":"127350525","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}
