Seminar course description [back to top]

Machine Translation (MT) refers to automatic translation from one natural language to another. To this date, even state-of-the-art systems are not able to provide high quality translations, except in some limited domains, such as weather reports etc. Moreover, the human effort needed to build a traditional MT system based on rules, transformations, or some kinds of knowledge representation formalisms is also substantial.

The availability of monolingual and parallel corpora enables the use of statistical methods for machine translation. A parallel corpus contains the same text in different languages. Parallel corpora are interesting because of the opportunity offered to align the original and the translated text and thus gain insights into the nature of translation. However, useful information for MT can be also gained by analyzing statistically monolingual corpora.

Significant improvements to translation system performance may be achieved using statistical approaches. Potential benefits of the statistical approaches include:

The following list outlines some topics that will or may be covered during the seminar. Some topics will be covered in more detail and some other themes will emerge during the seminar.

Course structure [back to top]

The seminar is namely organized as a knowledge building or progressive inquiry learning activity. In order to facilitate this process and to provide a possibility to attend to the course even for those in other universities than in Helsinki area, a web-based learning environment will be used. The course is thus given as a virtual course by using a specific web-based learning environment (Fle3) on the Internet. The course is organized in a workshop kind of fashion: The participants will form groups and participate to discussions over the internet. Each group will work on their selected topic, present their work orally in a final session, and write a scientific article.

There will be two meetings where physical attendance is required: At the beginning of the course there will be an introduction lecture and a guest lecture on the theme by Prof. Lauri Carlson. In addition, information on the basic arrangements and on how to use the learning environment will be given. At the end of the course, intermediate project works are presented orally in a full-day seminar.

Prerequisites for attending [back to top]

This special course is intended mainly for graduate students, however, advanced undergraduate students may also be admitted (please contact the course organizers). Each participant is expected to have reasonably advanced understanding of some discipline neighboring the domain of interest (machine translation, statistical methods, cognitive science, language philosophy).

Students, e.g., from the following disciplines and areas are welcome:

Successful participation does not require specific mathematical modeling or programming skills. However, basic familiarity with computational and/or mathematical modeling is useful.

Requirements for passing the course [back to top]
