Presentation on Service Oriented Business Models for ERP

Information Systems, Presentation, Service Science, Slides, SYSLAB

Today I gave a presentation on new business models for service oriented enterprise systems at the ARIS ProcessDays Nordic 2008. The presentation discussed how ERP functionality can be provided through services. New roles will emerge, like the platform provider who will provide support for a network of users and vendors. The audience showed much interest and posed questions about the consequences for ICT departments, whether security will be a problem for the new business models, the impact of open source, and the role of networks.

Seminar on three Human Language Technology research projects here at DSV

Health Informatics, Information Systems, Presentation, SYSLAB

Hercules Dalianis, Sumithra Velupillai and Martin Hassel held a lunch seminar on three Human Language Technology research projects here at DSV.

Hercules presented results from the project Tvärsök which aims to bridge the language gap between the Nordic countries. More specifically, if you search for documents in Swedish you should be able to find corresponding information in Danish or Norwegian if such are lacking for Swedish. The idea is that while you might have active knowledge of Swedish, in the sense that you can formulate search queries in that language, you might still be able to read and comprehend closely related languages even if you cannot effectively formulate queries in those languages (passive knowledge). This work has resulted in new lexical resources in the mobility domain as well as new methods for identifying parallel text [Hercules’ slides]

Sumithra presented ongoing work in the KEA project which concerns the medical domain. In this project we have access to a very large set of medical records, on which we aim to apply an array of text mining techniques. However, these patient files need to be de-identified before they can be exposed to a broader spectrum of researchers. A major part so far has been the development and porting of de-identification methods to Swedish. Parallel tracks are the exposing of relations between loosely defined features hidden in the vast amount of clinical data, as well as the identification of (un)certainty in diagnoses [Sumithra’s slides]

Martin presented two related projects on language technology based services for eGoverment. The first one, IMAIL, which just recently has been approved, concerns the automation of responses to requests sent by e-mail to the Swedish Social Insurance Agency (Försäkringskassan). These requests will be classified as recognised, in which case a predefined response can automatically be sent to the customer, or unrecognised and forwarded to a government official. In the latter case a tool already employed in the KEA project – Infomat – can be adapted to present the official with a view over previous transactions related to incoming request. The second project, still awaiting approval, “Intelligent cross-language services for eGovernment” is a quite ambitious extension to IMAIL which aims at further dealing with translation, multilingual authoring and cross-lingual information extraction for the Swedish minority languages [Martin’s slides]

William Song visits SYSLAB

Information Systems, Presentation, Slides, SYSLAB

Today William Song from the University of Durham gave a seminar on the Semantic Grid.

Abstract:
Many potential applications (still research topics at moment) across the web are investigated and studied. Among others, Web Services and the semantic Grid are two major research subjects which have attracted a lot of research efforts. A key problem with Web Services is how to automate the discovery and composition of web services so that it is effective and precise to find a flexible match between the service requesters’ requirements and the service providers’ description of their services. A key problem with the Semantic Grid is how to generate a virtual organization that is able to coordinate, share, collaborate, and flexible yet securely access to various resources, be they software or hardware, that reside on (geographically) different physical organizations. This presentation aims to share with you our recent investigation in these two aspects.

International Workshop on Value Modeling and Business Ontologies

Business Processes, Information Systems, SYSLAB

SYSLAB will organise a workshop on value modeling and business ontologies in Stockholm, Feb 9 – 10, 2009. At this International Workshop, two major approaches will meet: value modeling and REA. The REA (Resources, Events and Agents) model originating from the accounting domain is maturing to a conceptual framework and ontology for Enterprise Information Architectures in general. Value modeling is a business modeling approach that focuses on the value objects exchanged in business networks and that is supported by the e3-value tool set. Although the two approaches differ with respect to their main application areas, their ontologies have a lot in common.
The goals of this VMBO workshop are to bring together researchers with an interest in value modeling, REA systems, or the combination of the two, in order to present and discuss the current state of business modeling and to identify key areas for further research.

Reflections on Dissertation Defense

Health Informatics, Information Systems, PhD Dissertation, SYSLAB

I would never have thought that having a dissertation defense could be such a positive and memorable experience! After years of research work – with studies to conduct, papers to be written, editors and peer reviewers to convince and conferences to go to – and after some intensive spring and summer months struggling to finish the thesis, it was all heading for the grand finale. On the 17th of September, it was finally time for me to face the Professors of the evaluation committee. The subject of my dissertation: online health communities for people with established bad habits.

For those who have gone through this process, you probably know what I am talking about when I say that the time before the disputation is nerve shattering. While tuning the ideas and logic of the thesis, working with structure and sentences, you find yourself waking up in the morning with a feeling that you have missed something important. During this intensive period of work, I experienced that the discussions about cover illustration of the thesis gave me a welcome break. It made me think about colors and graphics instead of text paragraphs for a while. Then, when the thesis is finally printed, you start to wonder about the questions you will get at the dissertation defense, about the assessments of your work, and so on. Surprisingly, though, the seminar turned out to be a really nice experience! Having a group of Professors so engaged in your doctor’s thesis, and to be able to discuss with them about your ideas and results, this opportunity will probably come along just once! What a nervous but great moment this was! Examples of discussions at my seminar were about pros and cons of online health communities, empowerment and expertise of patients and citizens, the future of online health communities and how to improve the technical platforms. Not only was the past discussed, but the need to continue with future research as well!

The support from colleagues at the department, DSV, was also great! A diverse group joined the event; there were researchers and doctoral students, present and former colleagues, lecturers, student administrators, family members and other friends. It was a nice surprise to see that so many could make it! I am truly grateful for all support and encouragement! Everyone had put great effort into making it a memorable moment!

Below, you will find some pictures from the get-together held after the defense. The pictures were taken by Lotta Arnbom at DSV and my brother, Niklas.
