Context Aware Textual Entailment
… progresses and additional facts become known and context changes. It is often the case that we do not know an aspect of the story with certainty but rather believe it to be the case; i.e., what we know is associated with uncertainty or ambiguity. In this research a method has been developed to …

Context-Aware Resource Management
… schedule optimized.First, a detailed design of context capture systems in Linux's X-Window System is presented with an evaluation of the associated storage and computation overheads. Due to the overall low complexity of the application window representations, the overheads of computing …

Context-aware Personal Learning Environment
… none of the existing PLE architectures have context-aware systems embedded within their architecture. There is no intelligence in these architectures to filter the e-resources and to predict the user need. In addition, the current PLE architectures are not dynamic; it cannot adopt the user …

Context Aware Web-Service Monitoring
… approaches do not take into consideration the context of the users and how this context may affect the monitor activity. Consequently, a holistic monitor approach, capable of dealing with the dynamic nature of service-based systems and of taking into consideration the user context, would be …

Context-Aware and Secure Workflow Systems
… a piece of functionality within a given "context” and may be constrained by some security requirements. These activities are coordinated to collectively achieve a required business objective. The specification of such coordination is presented as a set of "execution constraints” which …

Context-aware data-to-text generation.
… event summaries often contain temporal contextual information, where the presented information is derived from the data of other previously occurring events, while in other situations the summary content is influenced by the environmental context in which the events take place. Current …

Context-Aware Credit Card Fraud Detection
… particular, we explore several means to leverage contextual information beyond a transaction’s basic attributes on the transaction level, sequence level and user level. On the transaction level, we aim to identify fraudulent transactions which, in terms of their attribute values, are globally …

An architecture for context-aware applications
… recent convergence of ubiquitous computing and context-aware computing has seen a considerable rise in interest in applications that exploit aspects of the contextual environment to offer services, present information, tailor application behavior or trigger adaptation. However, as a result of …

comMotion : a context-aware communication system
… information when the user is in the relevant context. This thesis describes comMotion, a context-aware communication system for a mobile or wearable computing platform. A behaviour-learning agent automatically learns the salient locations in the user's life. Once these places have been …

Policy-based approach for context-aware systems
… One important aspect of pervasive systems is context-awareness. Context-aware systems are those that can adapt their behaviours according to the current context. Context-aware applications are being integrated into our everyday activity aspects such as: health care, smart homes and …

Context-Aware and Adaptive Usage Control Model
… and highly mobile, changes in the environmental context or device context can affect the security of the system a great deal. A proper security mechanism must be put in place which is able to cope with changing environmental and system context. Usage CONtrol (UCON) model is the latest major …

Reflective mobile middleware for context-aware applications
… application designers. Applications have to be aware of, and adapt to, variations in the execution context, such as fluctuating network bandwidth and decreasing battery power, in order to deliver a good quality of service to their users. We argue that building applications directly on top of the …

Context-aware semantic analysis of video metadata
Im Vergleich zu einer stichwortbasierten Suche ermöglicht die semantische Suche ein präziseres und anspruchsvolleres Durchsuchen von (Web)-Dokumenten, weil durch die explizite Semantik Mehrdeutigkeiten von natürlicher Sprache vermieden und semantische Beziehungen in das Suchergebnis einbezogen …

Coordinated adaption for adaptive context-aware applications
… adapt to change is critical to both mobile and context-aware applications. This thesis argues that providing sufficient support for adaptive context-aware applications requires support for coordinated adaptation. Specifically, the main argument of this thesis is that coordinated adaptation …

Transforming Vulnerabilities into Context-Aware, Visible Risks
… remediation capability, and own environmental contexts. Threats need to be contextualized so that they become visible risks for remedial actions. Extant efforts need significant improvements to prevent malicious actors from exploiting exposed risks. Rigorously founded on theories, but pragmatic …

CASM: searching context-aware sequential patterns iteratively
Many applications are interested in mining context-aware sequential patterns such as opinions, common navigation patterns, and product recommendations. However, traditional sequential pattern mining algorithms are not effective to mine such patterns. We thus study the problem of searching …
