    Context-Aware Information Retrieval for Enhanced Situation Awareness

    No full text
    In the coalition forces, users are increasingly challenged with the issues of information overload and correlation of information from heterogeneous sources. Users might need different pieces of information, ranging from information about a single building, to the resolution strategy of a global conflict. Sometimes, the time, location and past history of information access can also shape the information needs of users. Information systems need to help users pull together data from disparate sources according to their expressed needs (as represented by system queries), as well as less specific criteria. Information consumers have varying roles, tasks/missions, goals and agendas, knowledge and background, and personal preferences. These factors can be used to shape both the execution of user queries and the form in which retrieved information is packaged. However, full automation of this daunting information aggregation and customization task is not possible with existing approaches. In this paper we present an infrastructure for context-aware information retrieval to enhance situation awareness. The infrastructure provides each user with a customized, mission-oriented system that gives access to the right information from heterogeneous sources in the context of a particular task, plan and/or mission. The approach lays on five intertwined fundamental concepts, namely Workflow, Context, Ontology, Profile and Information Aggregation. The exploitation of this knowledge, using appropriate domain ontologies, will make it feasible to provide contextual assistance in various ways to the work performed according to a user’s taskrelevant information requirements. This paper formalizes these concepts and their interrelationships

    This report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness.\ud To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST).\ud A general qualitative evaluation criteria for cognitive architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems

    Applying a unified public relations evaluation model in a European context

    The evaluation of public relations programmes has been a topic of keen interest to the public relations community for many years. A number of three level/stage models have been proposed to describe and explain the evaluation process. They have not been successful in terms of practitioner acceptance and have been criticised for being unrealistic and lacking feedback mechanisms. More recently the short-term and continuing models have been developed in response to these criticisms. This paper suggests a Unified Evaluation model which uses an established analysis of the communication/persuasion process as a framework to integrate and unify existing models that describe the public relations evaluation process. The proposed testing of this model in a European, transnational context is then outlined

    Economic management function of the state of the socialist Republic of Vietnam

    Mankind history has recorded the birth, development, survival struggle, and decline of various forms of states. Along with that process, the role and function of the State in socio-economic development have been strongly highlighted, represented not only social classes but also the characteristics of institutions, structures, and organizations of society in each period, and in accordance with the development of human cognition. The state in a socialist-oriented market economy has similar connotations and differences in comparison with states in general. However, due to the lack of clear definitions to distinguish the two concepts of "economic function" and "economic management function," the design, implementation, monitoring, and evaluation of the effectiveness of state management policies are ineffective, as right now there exist many fuzzy and overlapping gaps in theory. Not only that, the gap between the designed policy and the actualization of policy decisions is quite far from reality. Therefore, from the time the policies are established and issued until those policies take effects, there are many issues worth discussing

    Consciousness

    Consciousness is sometimes viewed as a particular parametric factor in the analogy of blood pressure or electric charge. The paper argues that this is an erroneous conception becomes consciousness involves a varied assortment of different phenomena that have no single unified commonality. And so even as ‘abnormal psychology’ has to be a disjointed assembly of diverse specialties so will ‘consciousness studies’ have to be

    Agricultural information dissemination using ICTs: a review and analysis of information dissemination models in China

    Get PDF
    Open Access funded by China Agricultural UniversityOver the last three decades, China’s agriculture sector has been transformed from the traditional to modern practice through the effective deployment of Information and Communication Technologies (ICTs). Information processing and dissemination have played a critical role in this transformation process. Many studies in relation to agriculture information services have been conducted in China, but few of them have attempted to provide a comprehensive review and analysis of different information dissemination models and their applications. This paper aims to review and identify the ICT based information dissemination models in China and to share the knowledge and experience in applying emerging ICTs in disseminating agriculture information to farmers and farm communities to improve productivity and economic, social and environmental sustainability. The paper reviews and analyzes the development stages of China’s agricultural information dissemination systems and different mechanisms for agricultural information service development and operations. Seven ICT-based information dissemination models are identified and discussed. Success cases are presented. The findings provide a useful direction for researchers and practitioners in developing future ICT based information dissemination systems. It is hoped that this paper will also help other developing countries to learn from China’s experience and best practice in their endeavor of applying emerging ICTs in agriculture information dissemination and knowledge transfer
