On the definition of generic multi-layered ontologies for urban applications

2000

Cooperation of information systems is essential for providing decision support for urban management applications. This involves sharing data across collections of the heterogeneous information systems that are used to manage large urban infrastructures. The objective of this work is to define a spatial ontology to describe key features of urban applications, providing a foundation for semantic reconciliation among heterogeneous spatial information sources. We propose a multi-layered ontologies definition framework consisting of ontology layers which are composed of a generic functional structure and one or more domain ontologies. The functional structure embodies general ontological concept…

Accessibility of Norwegian Municipalities Websites: A Decision Support Tool

2011

Access to public websites is crucial to assure equal opportunities for all citizens to participate in society. Although, a range of studies to analyse the accessibility of websites have been carried out, we have not been able to find any study evaluating the effect of managerial decisions on the accessibility of websites. This paper presents a demonstrator simulation model, built using System Dynamics methodology. The model focuses on accessibility of Norwegian Municipal websites, and is intended to be used as a decision support tool, mainly for managers responsible for website development and maintenance. To build the underlying model we have used information collected from in-depth interv…

Having the Final Say: Machine Support of Ethical Decisions of Doctors

2014

Machines that support highly complex decisions of doctors have been a reality for almost half a century. In the 1950s, computer-supported medical diagnostic systems started with “punched cards in a shoe box”. In the 1960s and 1970s medicine was, to a certain extent, transformed into a quantitative science by intensive interdisciplinary research collaborations of experts from medicine, mathematics and electrical engineering; This was followed by a second shift in research on machine support of medical decisions from numerical probabilistic to knowledge based approaches. Solutions of the later form came to be known as (medical) expert systems, knowledge based systems research or Artificial In…

A multi-methodology and sustainability-supporting framework for implementation and assessment of a holistic building renovation

La ristrutturazione degli edifici in futuro dovrà essere condotta secondo una prospettiva più olistica legata alla sostenibilità vista in una più ampia gamma di obiettivi/criteri e facilitata dagli scenari di ristrutturazione possibili. La ristrutturazione degli edifici dovrebbe servire a migliorarne le performance al fine di soddisfare le esigenze degli utenti, rendendo questi ultimi meno vulnerabili in relazione ai futuri costi energetici. Vi è un grande potenziale per ridurre il consumo di energia negli edifici esistenti. Tuttavia, ciò non deve comprometterè i valori architettonici e di qualità che rendono particolari. Pertanto, non possono essere semplicemente rinnovati, ma devono subir…

eHealth Initiatives for The Promotion of Healthy Lifestyle and Allied Implementation Difficulties

2019

Research in eHealth has opened a new dimension to improve personal healthcare with the help of information and communication technologies (ICT). eHealth is an ‘umbrella term’ for the use of ICT for health. Remote care-giving technologies (mHealth, Telehealth, Telemedicine) are an extended branch of eHealth initiatives. The concept of health e- Coaching is another promising initiative of eHealth research for real-time personalized lifestyle support. The focus of eHealth initiatives is to deliver high quality, evidence-based, secure, cost- effective, timely care to support people for sustaining a healthy lifestyle. However, the practical implementation of different eHealth initiatives has oft…

HCI for biomedical decision-making: From diagnosis to therapy.

2020

Abstract Human-Computer Interaction (HCI) plays a fundamental role in the design of software oriented towards clinical decision-making tasks. Currently, physicians have to deal with an ensemble of systems and software tools in the clinical environment, such as clinical Decision Support Systems (CDSSs), Electronic Health Records (EHRs), Picture Archiving and Communication Systems (PACSs). Moreover, additional platforms aim at collaborative work particularly in telemedicine, where rehabilitation technologies and conversational agents can support the healthcare professionals.

Decision support system for telemedicine based on multiple expertise

2002

This paper discusses results of the research in the area of artificial intelligence applications in telemedicine. The main goal of research is to manage multiple expertise obtained from experts-physicians in different countries to develop decision support medical system of broad earmarking based on telecommunication tools. The multilevel representation of medical data is discussed based on the apparatus of metastatistics. The technique is able to acquire semantically essential information from complex dynamics of quasi-periodical medical signals by applying recursively ordinary statistical tools. The voting-type technique is used to find consensus among medical experts in their description …

An ontological-based knowledge organization for bioinformatics workflow management system

2012

Motivation and Objectives In the field of Computer Science, ontologies represent formal structures to define and organize knowledge of a specific application domain (Chandrasekaran et al., 1999). An ontology is composed of entities, called classes, and relationships among them. Classes are characterized by features, called attributes, and they can be arranged into a hierarchical organization. Ontologies are a fundamental instrument in Artificial Intelligence for the development of Knowledge-Based Systems (KBS). With its formal and well defined structure, in fact, an ontology provides a machine-understandable language that allows automatic reasoning for problems resolution. Typical KBS are E…

Retail pricing decisions and product category competitive structure

2010

This study addresses the use of demand forecasting techniques by retailers to support their decision making. Specifically, the authors propose a pricing decision support model for retailers to estimate optimal prices, whose output depends on the configuration of a supporting measurement model. The measurement model is a demand function that relates sales and prices within the category; optimal prices are those whose effects on demand and retail margins maximize the category's profitability. This investigation focuses particularly on the role of competitive structure, such that the authors consider two types of price competition asymmetries for demand forecasting: those depending on the bran…

Prediction of lncRNA-Disease Associations from Tripartite Graphs

2021

The discovery of novel lncRNA-disease associations may provide valuable input to the understanding of disease mechanisms at lncRNA level, as well as to the detection of biomarkers for disease diagnosis, treatment, prognosis and prevention. Unfortunately, due to costs and time complexity, the number of possible disease-related lncRNAs verified by traditional biological experiments is very limited. Computational approaches for the prediction of potential disease-lncRNA associations can effectively decrease time and cost of biological experiments. We propose an approach for the prediction of lncRNA-disease associations based on neighborhood analysis performed on a tripartite graph, built upon …
