This paper extends decision theory under imprecise probabilistic information to dynamic settings. We explore the relationship between the given objective probabilistic information, an agent’s subjective multiple priors, and updating. Dynamic consistency implies rectangular sets of priors at the subjective level. As the objective probabilistic information need not be consistent with rectangulari...

THERAPID DEVELOPMENT OF networked information resources and services has not been matched with ongoing assessments of how well these resources and services meet user needs. This article stresses the importance of developing and implementing a range of user-based evaluation techniques as a means of assessing the usefulness of the services, and planning for future services. A number of user-based...

The objective of this study is to validate pseudo gold standards using multiple queries for biomedical document collection. Aspect query is a quasi similar query of the original query text which has the same information needs. Basic idea is that single information need can be represented in various expressions. Four aspect queries per one original query were created manually by fifteen numbers ...

Multimedia presentation generation has to be able to balance the functional aspects of a presentation that address the information needs of the user and its aesthetic form. We demonstrate our approach using automatic colour design for which we integrate relevant aspects of colour theory. We do not provide a definition of the relative importance of form versus function, but seek to explore the r...

While reading documents, people commonly make annotations: they underline or highlight text and write comments in the margin. Making annotations during reading activities has been shown to be an efficient method for aiding understanding and interpretation. In this paper we present a comparison of paper-based and online annotations in the workplace. Online annotations were collected in a laborat...

A searcher in a list of phrases which serves as an index to a set of documents often has problems nding the right words when the information sought for has to be described. O ering alternative phrasings and pointing to related concepts in the index could be a great help in this di cult process of query formulation. Usually the index is obtained by characterizing the set of documents. This paper...

The application of persuasive technology has been shown to be effective in a weight management context. However, it has been observed that the impact is not as significant as predicted. The aim of this project was to investigate whether a Design Thinking approach could generate new insights that could be used to drive the development of an innovative application to help people on their weight m...

International tourist arrivals worldwide reached 842 million in 2006. Many travellers fall ill while being abroad. The WHO advises travellers to get information about the destination especially when they have been ill before. In case of illness information, e.g. about doctors and hospitals, and communication, e.g. with relatives or the family doctor, are important. Although the combination of e...

Context: Companies need capabilities to evaluate the customer value of software-intensive products and services. One way of systematically acquiring data on customer value is running continuous experiments as part of the overall development process. Objective: This paper investigates the first steps of transitioning towards continuous experimentation in a large company, including the challenges...
