Sumithra Velupillai and Hercules Dalianis participated at the yearly GSLT, Graduate School of Language Technology Retreat. There where over 50 participants at the conference; PhD-students, supervisors and alumni from the whole of Sweden, see here for the conference programme.

DSV/KTH-Stockholm University is part of GSLT. At DSV we have one more GSLT PhD student at DSV namely Atelach Argaw who is supervised by associate professor Lars Asker. Dr. Martin Hassel at DSV is also one of the GSLT supervisors and he is also supervisor of Sumithra.

Sumithra presented two posters, one with title Mixing and Blending Syntactic and Semantic Dependencies. The research was been carried out during a GSLT phd-course in Machine learning together with the PhD students Yvonne Samuelsson, Oscar Täckström, Johan Eklund, Mark Fishel, Mark and Markus Saers. This poster was also presented at the Coling workshop CoNLL, in August 2008.

Hercules presented our patient data corpus, the Stockholm EPR corpus, and some experiments we have carried out on it.

I invite my colleagues to contribute with a paper to WSKS 2009 conference. The deadline for paper submission is March 24, 2009. For more information about this conference please access the following link: http://www.open-knowledge-society.org/summit.htm

Innovations in Information Systems Modeling: Methods and Best Practices, Edited By: Terry Halpin, John Krogstie, and Erik Proper, ISBN: 978-1-60566-278-7, IGI, link

Modeling is used across a number of tasks in connection to information systems, but it is rare to see and easily compare all the uses of diagrammatical models as knowledge representation in one place, highlighting both commonalities and differences between different kinds of modeling.

Abstract

This master thesis is about using parallel corpora and word alignment to
automatically create a bilingual Chinese-English dictionary. The dictionary
can contribute to multilingual information retrieval or to a domain specific
dictionary.

However, the creation of bilingual dictionaries is a difficult task
especially in the case of the Chinese language. Chinese is very different
from European languages. Chinese has no delimiters to mark word boundaries
as in European languages. Therefore we needed Chinese word segmentation
software to insert the boundaries between each Chinese word in order to
correspond with English words. That was one of the difficult issues in our
project. We spend half time on it.

Our parallel corpora consists of 104,563 Chinese characters, that is
approximately 50,000-60,000 Chinese words, and 75,997 English words, mainly
law texts. We used ICTCLAS as the Chinese word segmentation software to
pre-process the raw Chinese text, and then we used the word alignment system
Uplug to process the prepared parallel corpora and to create the Chinese-
English dictionary.

Our dictionary contains 2,118 entries. We evaluated the results with the
assistance of nine native Chinese speakers. The average accuracy of
dictionary is 74.1 percent.

It’s done, the “book” is now written, published, and defended. It’ been quite a journey – starting in autumn 2002, working through two research projects, countless (well, almost) teacher assignments on courses, working on the competing home-project (two kids – 2004, 2006). Although the journey never ends, the disputation defense was a welcomed station on the way. The opponent, Prof. Michel Leonard did a very good job of examining the thesis – and I hope that I was not as clueless at it looks on the picture when it comes to answering the posed questions. (Thanks to Nasrin for taking the great action picture!)

The conference was jointly organized by the University of Skövde, the University of Jönköping and SYSLAB. The goal of PoEM 2008 was to establish a dedicated forum where the use of EM in practice is addressed by bringing together researchers, users and practitioners. The goals of the conference were to develop a better understanding of the practice of EM, to contribute to improved EM practice as well as to share knowledge and experiences. The conference program consisted of 17 paper presentations addressing original and significant topics of Enterprise Modeling ranging from reports of innovative case studies to laying grounds to novel solutions in terms of methods and tools. The program faatured a keynote entitled “Information, architecture and other costly concepts” by Björn Nilsson, one of Sweden’s most experienced EM practitioners.
The highly interactive program of PoEM 2008 which included joint brainstorming sessions on the emerging topics of Enterprise Modeling attracted 47 participants both from academia and industry. The delegates came from many European contries as well as Canada and India.
