Abstract [en]

Personal communication between User-Centered Design (UCD) specialists and developers is important for communicating user needs and design solutions in agile development. In distributed projects where opportunities for personal communication are limited, the design documentation is an important surrogate. This study has investigated the perceived effectiveness of boundary objects in a distributed agile team, and their role in communicating target user needs. Six in-depth interviews with UCD specialists showed that the boundary objects rarely communicate underlying needs of the users but rather focus on interaction with the system that is being developed. The used boundary objects also do not work as stand-alone deliverables; they need to be explained and elaborated. Making the boundary objects comprehensive enough to be stand-alone is seen as too time consuming and not worth the effort. For agile projects with distributed teams, this creates hand-over and follow-up problems.

Abstract [en]

Currently one of the challenges for the ontology alignment community is the user involvement in the alignment process. At the same time, the focus of the community has shifted towards large-scale matching which introduces an additional dimension to this issue. This paper aims to provide a set of requirements that foster the user involvement for large-scale ontology alignment tasks.Further, we present and discuss the results of a literature study for 7 ontology alignments systems as well as a heuristic evaluation and an observational user study for 3 ontology alignment systems to reveal the coverage of the requirements in the systems and the support for the requirements in the user interfaces.

Abstract [en]

To evaluate and develop a service supported by an IT (information technology) system the intentionto use the future service should be in focus. The technology acceptance model (TAM) and the theoryof planned behaviour (TPB) can both provide knowledge about users’ intention to use a service,making them good models to base formative decisions on. Unlike TAM, TPB is concerned withspecific information related to the service context, and provide knowledge about what makes ITuseable.We used an adapted version of the TPB as the foundation for a formative service evaluationtechnique called F-SET.We applied the F-SET to a case where two subsequent versions of a serviceprototype were evaluated. The first prototype was a description of the service supported by Hi-Fidesign sketches showing what a web-based meal planning tool could look like. The second prototypeconsisted of both service processes and the web-based meal planning tool.To find relevant factors thatinfluence future use of such a service, a survey of 28 informants was conducted with the first prototype.The second prototype involved five families who used the service for two weeks.The feedback providedby the families, based on the factors identified in the pre-test, influenced the future direction of theservice development. Feedback from the informants was distributed between the service and the ITsystem, and the most common factors that influence the intention to use the service were time, price,usefulness and availability. Feedback included both positive and negative comments, as well as bugsand suggestions for improvements.We discuss potential improvements and what kind of informationto expect from the different constructs of the TPB.

Abstract [en]

Service design is said to be a holistic design approach. This is evident in most service design literature and textbooks but still services are prototyped by focusing on separate parts rather than whole service journeys. In this paper we propose a technique called service walkthrough that can be used to represent whole services. We explore what information can be generated using the technique and how useful it is. We found that the technique helped identify the flow of information, problematic areas, and design opportunities. The prototype was generally well received by the participants. In addition to earning about information, the technique also revealed insights about time and interdependencies of the various parts of the service. Some remarks are also made about when the service walkthrough can be used in the service development process and considerations concerning the fidelity of service walkthroughs.

Abstract [en]

The introductory course on human-computer interaction (HCI) and usable systems, taught early for the computer science and computer engineering education programs, has suffered from bad course evaluations. To investigate the students' beliefs and values in relation to the subject matter and the course, focus groups were used. The results indicate challenges with a lack of maturity and motivation among the students and that they wrongly perceive the subject matter as trivial. An approach for dealing with the challenges in the form of a course re-design is presented and implemented. The evaluation of the new course showed that it worked well and was greatly appreciated.

Abstract [en]

Unhealthy eating is an increasingly important problem in the western society. Our approach to this problem is to provide a meal planning system giving recommendations of suitable food recipes, taking important factors such as nutrient content, cost, variation, etc into account. A user controls how the system takes these factors into account through settings after which the system creates an optimal meal plan. The user can then iteratively refine the settings until a satisfactory meal plan is produced. The system is evaluated empirically in terms of ease of use and perceived usefulness, factors crucial for eventual user acceptance. The results are positive, and several interesting possibilities for future system improvements are discussed.

Abstract [en]

Since the description of the Semantic Web paradigm in 2001, technology has been proposed to allow its deployment and use. However, there is not yet any large and widely deployed set of semantically annotated Web resources available. As a result, it is not possible to evaluate the use of the technology in a real environment, and several assumptions about how the Semantic Web should work are emerging. In order to further investigate these assumptions and the related technology, we propose a simulation and evaluation platform. The platform provides tools to create SemanticWeb simulations using different technologies for different purposes, and to evaluate their performance. In this paper we introduce the model of the platform and describe the current implementation. The implementation facilitates the integration of technology for an essential operation on the Semantic Web, namely Semantic Web service discovery. We illustrate the use of the platform in a case study by implementing a SemanticWeb where the Jade multi-agent platform provides the framework to describe the agents, and a number of existing Semantic Web technologies are embedded in agent behavior.

This book constitutes the refereed proceedings of the International Workshop on Knowledge Discovery in Life Science Literature, KDLL 2006, held in Singapore in conjunction with the 10th Pacific-Asia Conference on Knowledge Discovery and Data Mining (PAKDD 2006).

The 12 revised full papers presented together with two invited talks were carefully reviewed and selected for inclusion in the book. The papers cover all topics of knowledge discovery in life science data such as text mining, identification and retrieval of documents, passage retrieval, co-reference resolution, extraction of life science entities or relationships from large collections, automated characterization of biological, biomedical and biotechnological entities and processes, extraction and characterization of more complex patterns and interaction networks, automated generation of text summaries, automated construction, expansion and curation of ontologies for different domains, and construction of controlled vocabularies.
