“…In his research, context is put into three categories: computing context, user context, and physical context. By these categories, Schmidt further defined context as knowledge of the user's and IT device's state, including surroundings, situation and locations [8].…”

Abstract-Context awareness is one of the most critical components in building information systems because the systems use that to warrant the relevance of provided information and users' needs. Existing research work in context awareness mainly focused on analyzing either Internetbased web pages or user search keywords. There are works that develop and utilize context awareness in the domains of information system and emergency management, however these works have not specified a comprehensive framework and a clear workflow about how exactly the critical contexts are captured and utilized to produce more effective and relevant instructions. In this paper, we have reviewed the related works in the cross domains of context awareness, mobile technologies and emergency management. After identified the limitations of these works, we have proposed a mobile context-aware information system that utilizes mobile technologies and context awareness to provide relevant emergency instructions to public users. Based on this system, we also described case studies that have been conducted to validate this system. Our motivation of this work is to fill in the gap of using context awareness and mobile technology for more efficient and effective emergency management and also provide reference for similar applications in other domains.Index Terms-Emergency management, mobile information system, context awareness, mobile software, XML. I. INTRODUCTIONIn order to properly react to and manage any emergency situation, it is vital to provide up-to-date, relevant information to both public community and emergency management centers regardless of geographical and temporal differences. Emergency situation develops fast and dynamically. Only latest information can help decision makers prepare updated instructions and only most updated instructions can efficiently help people reach safe places and save their lives. Meanwhile people in emergency can often give very little attention to the received instructions, meaning only most relevant instructions for each individual can be effective in instructing her to escape from the emergency.However, at present, most of the applications are static, which means the process of date collection, analysis and reaction is based on traditional process and technology, such as telephone and even just words. It limits the effectiveness and efficiency of emergency management. Clearly in order to improve the timeliness of delivering emergency instructions, we need to embrace the new information technology in building the emergency management system, Manuscript received May 4, 2014; revised September 9, 2014.

In fact, this has been made possible by recent development of handheld devices and mobile software technologies, which have together profoundly transformed the way how people communicate multi-media inf...

“…Context is defined as any information currently available in the environment that can be used to characterise the situation of an entity [24], such as its current location, the presence of other sentient objects in its vicinity or the state of its underlying infrastructure. In MoCoA, the contexts in which a sentient object can be during its lifetime are organised as a context graph, where only a subset of contexts can be transitioned to from the current context.…”

Abstract. Many programming models have been proposed to facilitate the development of context-aware applications. However, previous work does not offer support for building customised systems and has largely been targeted at a single application domain. In this paper, we describe MoCoA, a flexible middleware framework that permits the rapid development of context-aware applications and supports deployment scenarios ranging from augmented artefacts to city-wide smart-space applications. Crucially, MoCoA supports a small set of programming abstractions that are suitable for building a wide range of context-aware applications for deployment in a fixed or (ad hoc) mobile environment. For each of these abstractions, MoCoA provides a set of implementations via a library of components. We present three applications of the MoCoA framework that demonstrate both the use of the programming abstractions and the flexibility of the framework.

“…Contexts may be articulated in different ways depending on the underlying research domains, for example, [9], [10] and [11]. In the domain of knowledge management, we define knowledge visualization context as the information of any environmental entities that influences knowledge visualization design, implementation, application/use, and evaluation.…”

Adaptive Knowledge Visualization Systems: A Proposal and Implementation

Abstract-Visualizations are crucial to the creation, transfer and sharing of knowledge. However, there are three essential problems associated with existing knowledge management systems (KMS) and their visualizations. First, KMS tend to provide weak support for leveraging visualization to accomplish transformation, discovery and learning of knowledge. Second, KMS do not possess mechanisms to aid in sensing, analyzing and responding to contextual changes. Third, KMS are weak in adapting to diverse and changing problem and knowledge worker contexts. To address these problems, we propose and implement a contextual adaptive knowledge visualization model and system in this paper. Furthermore, we demonstrate the system implementation through a sequence of scenario-driven illustrations.
