    An empirical study of human Web assistants: implications for user support in Web information systems2001In: Proceedings of the CHI Conference on Human Factors in Computing Systems, New York, USA: ACM Press , 2001, 1, p. 404-411Conference paper (Refereed)
    Abstract [en]

    User support is an important element in reaching the goal of universal usability for Web information systems. Recent developments indicate that human involvement in user support is a step towards this goal. However, most such efforts are currently being pursued on a purely intuitive basis. This, empirical findings about the role of human assistants are important. In this paper we present the findings from a field study of a general user support model for Web information systems. We show that integrating human assistance into Web systems is a way to provide efficient user support. Further, this integration makes a Web site more fun to use and increases the user's trust in the site. The support also improves the site atmosphere. Our findings are summarised as recommendations and design guidelines for decision-makers and developers Web systems.

    Live Help Systems2003In: Human Factors and Web Development / [ed] Julie Ratner, Taylor & Francis , 2003, 2, p. -342Chapter in book (Other academic)
    Abstract [en]

    Due to the ever-changing technological landscape and the global integration of the Internet in schools, libraries, homes, and businesses, the content of this second edition changed significantly. Since many computer users are connected at both home and work, the Web has transformed communication; consumption patterns; and access to business, politicians, and neighbors halfway around the world. With numerous books on user-friendly Web sites, the editor's challenge was to deliver a volume with a radically different snapshot of the research being conducted at the beginning of the 21st century. The chapters in this book provide many answers to critical questions and propose thought-provoking research ideas for the future. Corporate and academic practitioners, as well as their doctoral fellows and graduate students from around the globe contributed their time, expertise, and unique research practices. Together, they collectively provide another comprehensive resource that the growing community of human factors and Web development experts can share. The editor's hope is that this book will inspire leading-edge research on accessible Web applications or other topics in the coming years.

    User modelling as an aid for human web assistants2001In: User Modeling 2001: 8th International Conference, UM 2001 Sonthofen, Germany, July 13–17, 2001 Proceedings / [ed] Mathias Bauer, Piotr J. Gmytrasiewicz and Julita Vassileva, Berlin/Heidelberg: Springer, 2001, Vol. 2109, p. 201-203Chapter in book (Refereed)
    Abstract [en]

    This paper explores how user modelling can work as an aid for human assistants in a user support system for web sites. Information about the user can facilitate for the assistant the tailoring of the consultation to the individual needs of the user. Such information can be represented and structured in a user model made available for the assistant. A user modelling approach has been implemented and deployed in a real web environment as part of a user support system, Following the deployment we have analysed consultation dialogue logs and answers to a questionnaire for participating assistants. The initial results show that assistants consider user modelling to be helpful and that consultation dialogues can be an important source for user Model data collection.

    Web Assistants: Towards an Intelligent and Personal Web Shop1999In: The Second Workshop on Adaptive Systems and User Modeling on the World Wide Web, 1999, 1, p. 5-12Conference paper (Refereed)
    Abstract [en]

    Electronic commerce has recently shown enormous potential to take over the sales market. There is a need to provide services that can reach individual computer users with different information profiles and levels of expertise. In this paper we introduce the novel concept of web assistants, human assistants working in an electronic web shop. This human-computer cooperation provides intelligent and personal services via an integrated communication media. A prototype of a web assistant system has been implemented. While browsing through the system the user can call for human assistance should the need arise. We present the results of a usability study performed on our prototype system. The results are encouraging especially when it comes to the attitude aspects of usability. The subjects were extremely enthusiastic about the concept of web assistants and its implications.

    User Modelling for Live Help Systems: Initial Results2001In: Proceedings of the Third ACM Conference on Electronic Commerce (EC'01), AMC Press , 2001, 1, p. 194-197Conference paper (Refereed)
    Abstract [en]

    This paper explores the role of user modelling in live help systems for e-commerce web sites. There are several potential benefits with user modelling in this context: 1) Human assistants can use the personal information in the user models to provide the users with efficient support tailored to their personal needs; 2) Assistants can be more comfortable in their supporting role; 3) Consultation resources can be saved, and thus, financial savings can be made for the e-commerce company. A user modelling approach has been implemented and deployed in a real web environment as part of a live help system. Following the deployment we have analysed consultation dialogue logs and answers to a questionnaire for participating assistants. The initial results show that assistants consider user modelling to be helpful and that consultation dialogues can be an important source for user model data collection.

    Interoperable and Easy-to-Use Web Services for the Bioinformatics Community - A Case Study2010In: The Second International Conference on Advances in Databases, Knowledge, and Data Applications, DBKDA 2010, 2010, p. 16-21Conference paper (Refereed)
    Abstract [en]

    In the field of bioinformatics, there exists a large number of web service providers and many competing standards regarding how data should be represented and interfaced. However, these web services are often hard to use for a non-expert programmer and it can be especially hard to see how different services can be used together to create scientific workflows. In this paper we have performed a literature study to identify problems involved in developing interoperable web services for the bioinformatics community and steps taken by other projects to, at least in part, address them. We have also conducted a case study by developing our own bioinformatic web service to further investigate these problems.
