Using Web Portals for Medical Information Mediation

By: Andrea Andrenucci
In: Licentiate thesis at Stockholm University
Abstract: The World Wide Web has become, since its creation, one of most popular tools for accessing and distributing medical information. In this research we evaluate the acceptance of online information, graphical user interfaces (GUIs) and personalized search services on medical information portals. We also discuss which QA (Question Answering) techniques better fit medical systems. The purpose of this thesis is to provide indications about how users search for health-related information and guidelines about how medical portals should be implemented to fit users' needs.

The results are based on a literary review of the main QA approaches and on the evaluation of a prototype that tailors the retrieval of documents from the Web4health portal to user background data. The evaluation is conducted through a user empirical study based on user observation and in-depth interviews. This study is, to our knowledge, the first observational study carried out to investigate the retrieval strategies of people searching for health information on a medical portal where different techniques for personalized search were implemented.

The results of this thesis are, to our knowledge, the first guidelines that cover both search services and GUI on medical portals. The guidelines are aimed to work as a checklist for developers involved in the implementation of medical portals on the Web.

Abstract: The purpose of this explorative study was to find out how Swedish users responded to Web4Health, a web-site about mental health, funded by the European Union. Twelve group-therapy patients and ten racket-hall visitors have tried the site by asking it a question about a psychological problem; thereafter, they have been interviewed. Subjects found the use of the web-site a valuable experience, and the interest in it was high. More than anything, the site stimulated the subjects’ thinking about their own situation. This was not only caused by the useful information that they got; equally important was the information that they rejected. We have borrowed a term from computer game developers, and called this "the cocktail party host effect": i. e. the provocation caused by information that did not fit the user’s needs gave rise to new thoughts and stimulated the subject to get more engaged in his or her problem.

The Difficult Art of Virtual Work – About introducing on-line group work for student teachers

In: EDEN Fifth Open Classroom Conference, 5-7 October 2005, Poitiers.

By: Eva Fåhræus and Sirkku Männikkö

Abstract: Several recent surveys indicate that student teachers are poorly equipped when it comes to ICT use in general and the pedagogical use of ICT in particular. The two-year research project within the Stockholm Institute of Education has investigated how students in the teacher education programme develop their professionalism, and how the use of information and communication technologies (ICT) in the educational setting can have bearing to this development. This paper analyses the ways the students have been working in small groups. Our findings indicate that the oral tradition in teacher education is strong and that more rigorous and systematic methods should be applied in order to establish and evolve learning practices that make use of ICT in the way that is relevant in the new Knowledge Society.

Report of first promotion stage for Web4Health

By: Jacob Palme

Download: http://web4health.info/documentation/D-6-2-first-promotion.pdf

Abstract: In order to get visitors to our web site, we designed our web site in such a way, that search engines (like Google) and portals (like Yahoo) will recommend our site. Such techniques are known under the name Search Engine Optimisation (SEO). The most important way of doing this is to make our site good, containing a lot of useful and valuable content.

In addition to this, it is also possible to rewrite pages so as to be easier reachable through search engines. A central method of doing this is to select our best pages, test different search queries which people might use when they look for the information in this page, and find out which of these search queries are actually often used by search engine users. For each of our page, 1-3 such good query phrases were found. In order to get search engines to recommend our page, we then must but this phrase into the <TITLE> tag, the <H1> tag, text on links from other pages to this page. In total, each phrase must be repeated 2-3 times in the body of the page.

Search engines give a site value based on the number of external links to this site. Links from good web sites have more value than links from less good web sites. Therefore, we wrote e- mail to the managers of many good web sites and asked them to provide a link to our site. In return, we made links to their site from our site.

It is important not to try to cheat the search engine by improper methods. However, the goal of our site is to give good information in the mental health area. Just like we optimize our own natural-language question-answering system to give the right answer to questions, the methods describe above means that we “optimize” Google to give the right answers to those questions where we have a good answer. Thus, SEO, as used by us, is within our goals of giving good information to people who ask for this information.

KOM2002 Groupware Use in Web4Health

By: Jacob Palme

In: Web4Health deliverables.

Download: http://web4health.info/documentation/KOM2002-groupware.pdf

Abstract: The KOM2002 Groupware is a software system to assist a group of experts in different countries to develop multi-lingual informational FAQs (answers to Frequently Asked Questions). Functions of this software are:

  • Storage of a large set of informational FAQs.
  • Each informational FAQ can have a number of attributes, selected freely for each user group.
  • Each informational FAQ can be provided in multiple languages.
  • A forum discussion can be associated with each informational FAQ.
  • Experts can easily modify the informational FAQs.
  • To avoid problems if two experts are simultaneously updating the same FAQ, warnings are provided when a second experts tries to edit a FAQ in a certain language, which another expert started editing within the last 24 hours.
  • Experts get regular e-mail notifications, informing them of what happens in the groupware, such as new discussion items, new FAQs, new translations, etc.

This document is a user instruction for using KOM2002 with the special document format to be used in the KOM2002 EU project for producing medical informational FAQs. This document is not a general instruction for using the groupware for other sets of FAQs, and it is not a managerial instruction for setting up and managing a data base using KOM2002.

Computer-based Psychological Counseling on the Web: an Empirical Study of Web4health

By: Andrea Andrenucci and Minna Forsell
In: World Conference on E-Learning in Corp., Govt., Health., & Higher Ed. 2004(1), 221-224.
Abstract: In this paper, we describe an empirical study of Web4health, a Question-Answering system created as a part of a groupware for psychological counseling on the Web. A group of twenty-two test users, 12 patients and 10 persons who have never had any contact with psychotherapy, tested the site submitting questions in natural language about psychological problems. Since our goal was to evaluate Web4health from a user perspective, we chose to apply qualitative research methods based on in-depth interviews and user observation in order to collect data. The results collected provide indications about how users experience computer-based counseling on the Web and how the online content should be presented.

Abstract: The representative system for electronic democracy combines the best from both a parliamentary system and direct popular voting. On every decision, citizens can decide whether to vote themselves, or let their elected representative vote for them. This system will give people more influence on decisions without requiring them to personally study each issue.

A Triple Helix of Learning Processes How to Cultivate Among Distance-Education Learners (In Swedish)

Swedish title: Inlärningsprocesser i en trippelspiral - Hur man kan odla lärande, kommunikation och samarbete bland distanslärande personer

In: Ph. D. Thesis at Stockholm University

Abstract: This work focuses on collaborative learning and how it can be applied and supported in distance education. Previous work indicates that distance learners experience more loneliness, technical problems and lack of stimulation than face-to-face learners do. Collaboration with peers may improve the feeling of connectedness and engagement. However, collaborative learning is not the answer to all problems in distance education--and it creates new problems. The present work explores problems, opportunities and processes when collaborative learning is introduced in distance education--and suggests solutions.

Related research on distance education and computer-supported collaborative learning is reviewed and related to own research. The different roles of information and communication technology in these areas are described.

Six own research papers are reviewed and integrated. Three of them explore university courses on computer use in society. Learners interacted mainly through a forum system, i.e. a system for text-based, asynchronous electronic conferences and discussions. The special character of forum communication had an impact on communication and collaboration processes. One paper summarizes these results and deduces a first list of tips to teachers and systems designers, aiming to reduce problems and take advantage of collaborativelearning opportunities.

One paper, a report to the Swedish School Board, provides an overview of research on distance education, with recommendations for use in secondary schools.

To get a broader picture of distance-education learners and their special situation and interests, a study was coducted in Australia. Most of the learners were secondary-school students, living far away from towns. Communication was normally restricted to mail, radio and telephone. Opportunities for collaboration between peers were rare, and correspondence traditions and the lack of technological infra-structure were delaying changes. However, a development towards more collaborative learning had started.

Empirical data were gathered ethnographically in natural course settings. Results were analysed using ‘activity theory’ as a framework.
The main contribution of this work is a description on how three groups of learning processes develop and interact: (a) of content, (b) of communication, and (c) of collaboration. They form the spiralling model of a “Triple Helix”. Finally, detailed advice is given as checklists to organisations, teachers, learners and system designers.

Adapting Hypermedia for Psychological Counselling

By: Andrea Andrenucci
In: Poster Proceedings of the 14th ACM Conference on Hypertext, Nottingham, UK, August 2003.
Abstract: This paper describes an ongoing research oriented to find an approach to adapt the answers retrieved in an Information Retrieval Hypermedia system to users characteristics such as interests, problems and needs. The software utilized in this research is an automated question answering system that answers queries about psychological or life problems and is designed to be used on the WWW. The approach reported in this paper uses explicit and implicit acquisition of information through a dialogue with the user in order to create a user model that should be compared with the knowledge base of the system.

Natural Language Question Answering System Classification Manual

By: Jacob Palme and Eriks Sneiders
Abstract: The natural-language question-answering system used in Web4health is based on manually specifying templates for each FAQ (Frequently Asked Question).The templates are matched against the questions asked by users.The success of the question-answering thus depends a lot on the quality of these templates.This manual describes the format and method of producing templates.

A Personal History of CMC

Based on more than 30 years of experience in using and designing computer systems, this paper summarizes a somewhat controversial view on how software should be designed to be liked by its users. Basic to this view is that it is dangerous to use computers to ensure adherence to rules, laws and regulations. When rules are interpreted by humans, the humans are capable of interpreting the rules with discretion and understand that quite often, the rule should not be adhered to 100 % in every case. Computers are not so good at making such judgements.

Select Protocol Specifications

The SELECT rating system is a system for storing and using ratings on Internet resources. Ratings can be provided by ordinary readers of the resource, by expert readers, by computer linguistic analysis of the documents, or by observation of user behaviour. This specification describes the protocols needed between different program modules to provide the SELECT service. Protocols are specified to find out how documents are rated, to send ratings, to register a rater, to search for rated resources, to evaluate a list of resources (get their ratings), to find new items with good ratings, and to exchange ratings data between SELECT servers.

Ethnographic Methods in the Study of Electronic Communities

The origins of ethnography lie in social anthropology. In recent times, however, ethnographic methods have found an increasing role within IT design and development (Anderson, 1994). In such cases, an ethnographic researcher is, in an integrated way, engaged in describing, planning and participating in a process of change, rather than merely observing and describing an existing setting.

Internet, Usenet News, and child pornographic film clips

In order to establish if a newsgroup within the internet conference system Usenet News that is used to distribute child pornography is accesible through news servers operated by a company that provides access for anyone to their news servers for a monthly fee, an account with such a company was opened. Out of the 36 movies 9, or 25%, consisted of child pornography, including oral sex. The ages of the children roughly varies from 4 to 11 years of age (estimates by the author), and the length of each of the 9 movie clips was up to 6 minutes.

Collaborative Filtering of Web and News (EU SELECT Project)

Collaborative filtering systems are software systems to help Internet users find the most valuable and interesting information, aided by other people's ratings. Some collaborative filtering systems will even tailor the filtering to your particular needs, interests, competence and values, by using rating values produced by other people with similar views as yours. This paper gives a short overview of existing such tools with links to further information, and then discusses some issues in their design and presents an architecture for a rating and filtering system. This architecture is defined such that modules implemented by different people at different places can interwork.

Decision Support by E-mail

Research on the use of e-mail for decisions shows that e-mail has some important advantages, compared to face-to-face meetings. But e-mail also has particular problems for use in decision-making, probably caused by the lack of body language, facial expressions and voice inflection. These problems show themselves in too longwinded discussions and difficulty to reach a decision. This paper discusses these problems, and proposes that new computer-supported tools might alleviate the problems. Examples of such tools are methods to find out the opinion in a group, continuously during its deliberations, and methods to structure the message flow with links between messages like "Solution-To", "Argument-Against", etc. These links would be an extension to the existing links "In-Reply-To", "References" and "Supersedes" giving more flexibility in structuring the information flow.

The Future of Electronic Mail

This paper tries to make predictions about the future of e-mail, based on a questionnaire distributed to e-mail experts and on the experience of the author. The paper goes through all major e-mail functionality which can be expected to arrive in the next five years. In particular, the paper predicts that future e-mail software will provide better facilities for organizing and searching large mail data bases, that HTML-formatted messages will become common and support for work flow and group communication will be better.

User Influence on Software Design may give less Good Software

Of course, user influence on software design is useful and good. This document is in no way intended to say that user influence on software design is bad or should not be used. One should however be aware, that user influence on software design can have not only positive but also negative effects on the quality of the software. Here is an explanation why.

Can Computers Decide what is Right and Wrong?

It is dangerous to use computers to ensure adherence to rules, laws and regulations. When rules are interpreted by humans, the humans are capable of interpreting the rules with discretion and understand that quite often, the rule should not be adhered to 100 % in special cases. Computers are not so good at making such judgements. Because of this, it can be unsuitable to put to much of rule-checking into software.

Spin a Web Between the School and the World

A distance course about the Internet was provided for Swedish high school teachers. Course design was based on constructivist ideas about teaching and learning. The Internet was used for communication during the course. In the qualitative evaluation of the course we are discussing our findings about communication strategies, group interaction, and knowledge-creating processes. Participants developed various strategies for communication and learning where they combined asynchronous and synchronous forms. Through collaborative learning they have created new ways of applying the Internet in their teaching. We also found that computer conferencing systems need to be developed in order to support teaching in a more efficient manner.

Creating Places for Teaching and Learning

The use of technical media for communication is altering the spatial and temporal dimensions of social life so that boundaries characteristic of face-to-face interaction can be ignored. The use of technical media enables individuals to reorder the spatial and temporal features of social organisation, and to use these reordered features as a means of pursuing their objectives. The emergence of the new communication technology has resulted in the uncoupling of space and time: spatial distanciation no longer requires temporal distanciation. We can now communicate in spite of great distances without significant temporal delays. Another important development following from the uncoupling of space and time is the despatialized simultaneity. Earlier, "the same time" presupposed "the same place". The development of the new communication media allows us to experience events as simultaneous despite the fact that they occur in places that are spatially remote. Implications of this development in the area of teaching and learning are discussed in this paper through an example of a distance course designed for teachers in the use of Internet in senior high school education.

MIME E-mail Encapsulation of Aggregate Documents, such as HTML (MHTML)

Although HTML [RFC 1866   Rating ] was designed within the context of MIME, more than the specification of HTML as defined in RFC 1866 is needed for two electronic mail user agents to be able to interoperate using HTML as a document format. These issues include the naming of objects that are normally referred to by URIs, and the means of aggregating objects that go together. This document describes a set of guidelines that will allow conforming mail user agents to be able to send, deliver and display these objects, such as HTML objects, that can contain links represented by URIs. In order to be able to handle inter-linked objects, the document uses the MIME type multipart/related and specifies the MIME content-headers "Content Location" and "Content-Base".

Intelligent Filtering on Usenet News - a User Study

Language: English
URL: not yet available on the Internet

Three users read texts in large Usenet News newsgroups using a news reader with special support for information filtering. Users could put messages into baskets. Their actions were recorded by the system, and a filtering algorithm tried to perform similar filtering on a new set of netnews articles. The users were interviewed on their experience of using the filtering newsreader. One important conclusion is that it might be more satisfying for users with a filtering system which aids the users in rapidly filtering information manually, than in a system which performs the filtering automatically.

Risk@Internet. An experiment in using an e-mail mailing list as a forum for discussion and information dissemination on the subject of risks.

Language: Swedish
URL: Not yet available on the Internet

An experiment was performed on the usability of e-mail mailing lists as a vehicle for distribution of information on the subject of risk management and risk research. Some experts in this area were asked to participate, together with people who are important for distribution knowledge in society, such as journalists, teachers, politicians, authors, etc. The experience was not entirely successful. It was not easy to get experts who were willing to answer question on this issue with non-experts. The experts wanted an expert-only mailing list. At the end of the test period, some mailing-list saboteurs joined the list, trying to take over the discussions to discuss their pet issues. The conclusion is that to succeed with this kind of usage, you should pay the experts to participate, and you should have control on whom to invite to avoid mailing-list saboteaurs which will occur in lists where anyone is allowed to participate.

Internet, Usenet News and the distribution of pictures of nude children

In order to establish if the internet conference system Usenet News is used to distribute either child pornography or more innocent pictures of children in the nude all postings in four news groups dealing with pornographic pictures were examined during a 7-day period. During this time 5651 postings were made in the four news groups, out of which 807 were pictures. Among them were eight pictures of 8-13 year old (estimates by the author) children in the nude. None of the pictures show intercourse or other explicit sexual activity.

Internet, Usenet News och alt.sex.pedophilia

In order to establish if child pornography is being distributed via the Internet conference system Usenet News through news groups not easily accessible to all users, a connection to Usenet News was established through a news server providing access to all existing news groups with world-wide distribution (not necesarily the case with all servers). During this time 417 postings were made, out of which 28 were pictures. Seventeen of the pictures show children either in sexually expicit poses or actually performing sexual activities, including oral sex and intercourse.

In the spring of 1995, the department of computer and systems sciences gave a course on the topic "Humans, computers and society". The teaching methods differed very much from traditional methods. Most of the course activity was students reporting from books and papers and discussing with each other in a non-simultaneous computer conferencing system. Instead of traditional exams, students were passed and given marks based on their activity in the system. Results of the study are that the teaching results were as good as in traditional teaching. The study also showed that women and students which did not have Swedish or another Nordic language as their native language succeeded a little better than men and Nordic students. The students liked the freedom to plan their studies and the exchange of information, but complained over too much to read and too little support from the teachers.

The World Wide Web provides good methods for making information available for retrieval, but does not provide methods for letting people discuss and comment on the information provided. It would be useful to be able to have non-simultaneous discussions on the contents of normal web pages, using non-simultaneous computer conferencing techniques (like Usenet News newsgroups). Several methods to do this is discussed in this paper, for example adding "Start discussion" and "Discussion exists" buttons to the ordinary web pages, where these buttons would lead to a computer-conferencing discussion of the web page. Some of the options described here will be implemented in the Web4Groups project, a research project financed by the telematics program of the European Union (EU). An appendix presents the naming principles used in Web4Groups   Rating .

You have 134 Unread Mail - Do You Want To Read Them Now?

Electronic mail system can, if used by many people, cause severe information overload problems. The cause of this problem is that it is so easy to send a message to a large number of people, and that systems are often designed to give the sender too much control of the communication process, and the receiver too little control. The solution to the problem must be too increase the control of the receiver. To do this, structure Is needed on the set of messages. Electronic mail systems thus need to be more data base oriented, like some computer conference systems already are.

Experience with the use of the COM computerized conferencing system

Reports from a number of different studies on the usage of the KOM computer conferencing system in the beginning of the 1980-s. Among the conclusions found are that most communication is new communication, not a replacement for old communication, that young people and non-bosses get an advantage in KOM usage while old people and bosses had an advantage in face-to-face meetings, that users generally felt that KOM increase equality and participation.

Lotus Notes Invented in the 1970s

This paper was written in 1978 and published at the international conference Teleinformatics in Paris in 1979. The paper is also available in the book published based on this conference. The paper is of interest, because it describes (in chapter 3-4) a computer system very similar to Lotus Notes and to so-called work flow applications. The paper thus shows that the ideas in Lotus Notes existed already long before Lotus Notes was invented, many of the ideas go even further back to the Emisari system invented by Murray Turoff in 1969.

The General Public Information System

This paper was written by me in the Nordic magazine Data No. 3, 1974. It phrophesises much of what Internet has become today. The dreams were with us also 23 years ago, even if the dreams would not be realized until many years later.

Original abstract of the 1974 paper:

Conventional computer application systems will often cause inflexibility and difficulty for the individuals and organizations using them to adjust to new needs and environmental situations. This paper proposes a way of designing computer application systems as an extension of the idea in teleconferencing systems. The concept "conference" is extended to the concept "activity" which can be a conference, a person, a computer program, an inquiry, a set of travel accounts, a set of records in a data base system etc. Each activity consists of messages or notices which can contain both ordinary text and information structured into fields with typed values. This way of designing computer systems may give more flexibility and may make it easier to adjust the system to new needs and environments.

Which are the human needs that are affected by the use of computers? How will computers affect the humans using them? What kinds of communications between humans will the computers cause? How can computer systems be designed to better satisfy human needs? What design principles should be used for such systems? What kinds of human-machine interaction will better satisfy human needs?
