The GF Resource Grammar Library (RGL) implements the morphology (inflection) and basic syntax (phrase structure) of more than 30 languages: Afrikaans, Bulgarian, Catalan, Chinese, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hindi, Interlingua, Japanese, Italian, Latvian, Maltese, Mongolian, Nepali, Norwegian bokmål, Nynorsk, Persian, Polish, Punjabi, Romanian, Russian, Sindhi, Spanish, Swedish, Thai, and Urdu. These resources are freely available as open-source software.
We are constantly welcoming new languages, especially from new language families. Learn more at the RGL status page. The summer school is an excellent place to get started with a new language.
A recent Google TechTalk gives an overview of the GF technology and its many applications:
You will find the GF book a very good companion to your studies (available also as an e-book). However, the book is not a requirement for successful participation in the summer school.
Register from the official SMU website. On the linked page, there is a link to registration at the top right of the page.
Participation fee for two weeks will be 200 SGD, and 120 SGD for a single week. This applies for both online and offline participation. If you want to apply for a participation grant, please contact the organisers.
The summer school is co-organised by Singapore Management University's Centre for Computational Law. The interests of the research centre lie at the intersection of logical formalisation, knowledge representation and natural language generation.
Our second theme is Abstract Wikipedia: an effort in multilingual natural language generation at a large scale, targeting a diverse set of languages and language families.
The special themes are present in two ways:
The summer school is pefectly suitable for a student who is interested in other aspects of grammar engineering.
All times are indicated in Singapore time.

The summer school will take place in Singapore, home to Singapore Management University.
Because of the Covid-19 pandemic, it is possible to participate in the summer school fully online. Read more in Logistics.
We aim to make the summer school as smooth as possible for people on different time zones.
Other than the hybrid online/offline nature, the program of the summer school will be like in the previous years. The first week is a GF tutorial, and the second week is more specialised tracks.
The first week's talks will be given to a live audience in Singapore at 9-12 SGT, and streamed live—if you're in Asia, or otherwise awake at this time, you can follow them live and ask questions on Zoom.
On the first day of the summer school, Aarne Ranta will give a duplicate of the morning talk at 20 SGT, which is 14 CEST -- this is afternoon in Europe and Africa, and morning in most of the Americas. We will evaluate the format after the first lecture and decide if and how to do rest of the duplicate talks. If you would like to participate, but can't make it on the first day, please contact the organisers.
