Eriks Sneiders held a lunch seminar about his research in automated question and e-mail answering. The research has lead to real life systems, such as a QA engine for Trygg-Hansa and e-mail answering engine for Gjensidige Försäkring in Sweden. The systems demonstrate rather high performance figures, thanks to granularity of the knowledge representation.
Agreement with ARIS on BPM tools
The department has signed an agreement with ARIS on using their Business Process Management platform for teaching and research. Initially, it will be used in courses for Enterprise Modelling. ARIS is one of the leading vendors of enterprise architecture platforms.
“ARIS Platform provides integrated software products that help enterprises to continuously improve their business processes. These products cover every phase of a BPM project—from strategy definition and process design to transferring the models into your IT systems and monitoring process execution.” (cited from the ARIS web site)
The BPM 08 conference in Milano
Today I returned from a conference trip to the Business Process Management (BPM) conference, which was held 1-4 of September 2008 in Milan, Italy.
On the 1st of Sept. I gave a presentation on the workshop Business Process Management and Social Software, held in conjunction with the conference. I presented the paper “Business Process Management with Social Software Systems – a New Paradigm for Work Organisation” coauthored by Paul Johannesson and Birger Andersson and myself.
The slides from the presentation can be downloaded here

Outstanding summaries for many of the presentations can be found on Sandy Kemsley’s blog. (Only presentations which went in parallel are missing there.) I am glad Sandy joined my presentation and the feedback I got on it through her blog post. Thanks Sandy!
Personally, I very much enjoyed the tutorial by Wil van der Aalst on Process Mining. During this tutorial, Wil gave an excellent overview of the existing approaches for mining process models from log files. He went trough:
– the Alpha algorithm;
– Multi phase miner;
– Genetic mining; and
– Region-based approaches (both state-based regions and language based regions).
Furthermore, Wil spoke about discovery in the data and the organisational perspectives. He concluded the tutorial with a demonstration of ProM, which is an open-source process mining toolkit supporting a variety of process mining techniques with more than 230 plugins.
LOUHI ’08: The First Conference on Text and Data Mining of Clinical Documents, September 3-4, Turku, Finland
Sumithra Velupillai and Hercules Dalianis attended LOUHI ’08: The First Conference on Text and Data Mining of Clinical Documents in Turku, Finland, September 3-4.
At Louhi ’08 Sumithra and Hercules presented the work-in-progress proposal paper Diagnosing Diagnoses in Swedish Clinical Records. In this paper, planned text mining research on electronic clinical records written in Swedish are described. The work is part of the KEA-project and the proposed work will start this autumn. The paper can be found here:

The conference gathered people from all over the world working on similar research projects, and many valuable contacts were established. Hercules and Sumithra were proposed to continue the conference and organize it in Sweden next time. We were honoured and accepted of course to carry out the next conference in Sweden.

New project proposal to Vinnova: Beslutsstöd genom utforskning av patientjournaler
Sammanfattning:
I projektet ämnar vi konstruera en demonstrator från våra befintliga verktyg som vi har utvecklat inom det Vinnovastödda KEA-projektet. Med verktyget kommer användaren att kunna utforska helt avidentifierade patientjournaler för att finna både synliga och dolda samband mellan sjukdomar, diagnoser, kost, social situation, medicinering, mm. Indata som kommer att användas för att åstadkomma detta är hundratusentals patientjournaler som forskargruppen på DSV/Stockholms universitet har fått tillgång från Stockholms läns landsting.
Demonstratorn kommer att efter projekttidens tid att kommersialiseras för att komma sjukvården och samhället till nytta.

SAMMET Project Kick Off
Today, we had the kick-off meeting for the SAMMET project – Methods for Customer Interactive Service Design. Representatives from SYSLAB, Linköping University, University of Skövde, Dataföreningen, Ericsson, SAS, Volvo, and Skatteverket participated in the meeting. We discussed the needs of the organisations, which ranged from novel e-services for citizens to interoperability architectures for global enterprises. Furthermore, the researchers presented a number of model and method components including tools for value and goal analysis, interaction design, and participative service modelling.

Presentations at CoNLL and MMIES2 in Manchester, August 16 – 23 2008
Sumithra Velupillai attended the Twelfth Conference on Computational Natural Language Learning (CoNLL) and the Workshop MMIES-2: Multi-source, Multilingual Information Extraction and Summarization (MMIES2), both held in conjunction with The 22nd International Conference on Computational Linguistics (Coling) in Manchester, August 16 – 23. Coling is one of the most important conferences in Computational Linguistics, with around 500 attendants.
At CoNLL Sumithra presented the article Mixing and Blending Syntactic and Semantic Dependencies together with her colleagues Yvonne Samuelsson, Oscar Täckström and Mark Fishel during a poster session at the conference. The work was the result of joining the shared task Joint Learning of Syntactic and Semantic Dependencies within the course Machine Learning 2 organized by GSLT. The group ranked 6 out of 20!

At MMIES2 Sumithra presented the article Automatic Construction of Domain-specific Dictionaries on Sparse Parallel Corpora in the Nordic languages which was co-written with associate professor Hercules Dalianis. In this article Nordic domain-specific dictionaries were created automatically by utilizing multilingual corpora from the web site Hallå Norden and a word alignment approach. The work was part of the research project TvärSök.
