Opinions on the web present a wealth of information that can be leveraged in our day to day decision making tasks ranging from which product to purchase to which doctor to consult for a particular ailment. Due to the large volume of opinions available from different sources across web, digesting all the available opinions is a time consuming process which can severely impair user productivity. ...

. A decision support system SonaRes destined to guide and help the ultrasound operators is proposed and compared with the existing ones. The system is based on rules and images and can be used as a second opinion in the process of ultrasound examination.

A multicriteria decision support system called MultiChoice is presented in the paper. It is intended to support decision makers in solving various multicriteria analysis problems. Different well-known methods and software systems are considered. The structure, the functions and the user interface of the system are described.

Welcome to this special issue of the Information Technology and Management journal on knowledge based decision support systems. The main goal for this special issue is to be a timely vehicle for publishing selected research papers from academia and practitioners in different industries on this emerging topic. Knowledge-based decision support systems are systems designed to ensure more precise d...

Collective intelligence has been defined as the ability of a group to provide more effective solutions to problems than could be otherwise provided by any of its individual members working alone. Social-structures are the means by which humans are able to synergistically combine their efforts to provide high-quality solutions to the problems facing the group. Over time, these structures have gr...

We develop a decision support system, based on the data warehousing approach. We define a conceptual object-oriented data warehouse model, which describes the data warehouse as a central repository of relevant, complex and temporal data. Our model integrates three concepts: warehouse object, environment and warehouse class. Each warehouse object representing a source entity, is composed of one ...

The Decision Support Information Gathering System, Digs, uses influence diagrams to model user’s decisions and to calculate the value of imperfect information for each available information source. The system then plans and executes the information gathering process providing the most valuable information to the user. Thus, the system saves time and cost of, sometimes random, search for informa...

Many safety-critical systems have a human-in-the-loop for some part of their operation, and rely on the higher cognitive abilities of the human operator for fault diagnosis and risk-management decision-making. Although these operators are often experts on the processes being controlled, they still sometimes misjudge situations or make poor decisions. There is thus potential for Safety Decision ...
