Cloud computing is a promising IT paradigm which enables the Internet's evolution into global market of collaborating services. semantic interoperability plays key role in making this reality. Towards direction, comprehensive and systematic survey efforts by standardization groups, industry research community carried out. The main objective to derive an initial set requirements be supported existing as well next generation systems. Ôhe motivates encourages adopt common framework with core...
This paper focuses on the emerging problem of semantic interoperability between heterogeneous cooperating Cloud platforms. We try to pave way towards a Reference Architecture for Semantically Interoperable Clouds (RASIC). To this end, three fundamental and complementary computing paradigms, namely computing, Service Oriented Architectures (SOA) lightweight semantics are used as main building blocks. The open, generic introduces scalable, reusable transferable approach facilitating design,...
Ensemble learning can improve predictive performance compared to the of any its constituents alone, while keeping computational demands manageable. However, no reference methodology is available for developing ensemble systems. In this paper, we adapt an framework patent classification assist data scientists in creating flexible architectures text by selecting a finite set constituent base models from many alternatives. We analyze axes along which someone select system and propose combining...
Given the rapid uptake and great diversity of PaaS offerings, understanding semantic interoperability at level is essential for supporting inter-Cloud cooperation, seamless information exchange application data portability. In this vein, paper introduces a framework (PSIF). PSIF studies, models tries to resolve conflicts raised during deployment or migration an by defining following dimensions: Fundamental Entities, Types Semantics, Levels Semantic Conflicts. context paper, development...
Conversational agents are reshaping our communication environment and have the potential to inform persuade in new effective ways. In this paper, we present underlying technologies theoretical background behind a health-care platform dedicated supporting medical stuff individuals with movement disabilities providing advanced monitoring functionalities hospital home surroundings. The framework implements an intelligent combination of two research areas: (1) sensor- camera-based collect,...
Electronic Health Records (EHRs) contain an increasing wealth of medical information. They have the potential to help significantly in advancing research, as well improve health policies, providing society with additional benefits. However, European healthcare information space is fragmented due lack legal and technical standards, cost effective platforms, sustainable business models. The vision Linked2Safety advance clinical practice accelerate by pharmaceutical companies, professionals...
Many thousands of patent applications arrive at offices around the world every day. One important task when a application is submitted to assign one or more classification codes from complex and hierarchical schemes that will enable routing examiner who knowledgeable about specific technical field. This typically undertaken by professionals, however due large number potential complexity an invention, they are usually overwhelmed. Therefore, there need for this code assignment manual be...
A set of well-integrated clinical terminologies is at the core delivering an efficient trial system. The design and outcomes a can be improved significantly through unambiguous consistent used in participating institute. However, due to lack generalised legal technical standards, heterogeneity exists between prominent as well within systems several levels, e.g., data, schema, medical codes. This article specifically addresses problem integrating local or proprietary with globally defined...
We present work in progress on an intelligent embodied conversation agent the basic care and healthcare domain. In contrast to most of existing agents, presented is aimed have linguistic cultural, social emotional competence needed interact with elderly migrants. It composed ontology-based reasoning-driven dialogue manager, multimodal communication analysis generation modules a search engine for retrieval multimedia background content from web conducting given topic.
We present work in progress on an intelligent embodied conversation agent that is supposed to act as a social companion with linguistic and emotional competence the context of basic health care. The core ontology-based knowledge model supports flexible reasoning-driven planning strategies. A dedicated search engine ensures provision background information from web, necessary for conducting specific topic. Multimodal communication analysis generation modules analyze respectively generate...
This paper presents IMMERSE, a system that offers number of ICT-enabled services to address the challenges migrant integration, focusing on: (i) covering migrants' needs for validated information, (ii) addressing specific socio-cultural, economic and legal aspects, (iii) improving access labour markets. IMMERSE is mainly designed cover information migrants can be either general guidance or personalised based on their needs, skills interests. with case study example which demonstrates...
In this paper, we present work in progress on the development of a smart monitoring framework to support people with motor disabilities and their caregivers clinical non-clinical rehabilitation care environments. The innovation platforms lies combination solutions, such as activity recognition lifestyle tracking, an intelligent virtual agent that aims empower motivate need through personalized feedback responses, well assist clinicians easily collect information about patients. proposed...
