What is this place?

This is a place for keeping some of the research works that have been done at “lab 603/604” here in the Institute of Information Science, Academia Sinica, and for showing what is happening here now. “Lab 603/604” is the room labelled with the numbers 603 and 604 on its door — naturally — and is situated at the southern wing on the 6th floor of the institute's new building. We are located in the Nangang District, Taipei City, Taiwan.

A lot of research works are being done here. This place you are visiting now, called Guava, maintains only those that are being carried out by Tyng-Ruey Chuang, Shin-Cheng Mu, and their colleagues, including the many articulating and hard-working research assistants in the lab. Some of the research assistants are still here, but many of them have taken off for advanced studies in Taiwan or abroad, or, sigh, have taken up better-paying jobs elsewhere.


  • As always, we offer internship to both undergradate and graduate students. Please contact us for details.


Our research work can be roughly categorized into the following five areas:

  • Functional Programming : It cannot be emphasized enough that both Tyng-Ruey and Shin-Cheng are functional programmers, though they differs in their native languages (ML for one but Haskell for the other).
  • XML and Web Technologies: XML and related standards (err, W3C recommendations) are our daily working languages! We are very good in using open-sourced software tools building integrated Web-based systems.
  • Open Geospatial Information: Be them topographic maps or socioeconomic maps, GML or SVG, we have done them all! Now we are into collaborative geospatial mapping.
  • Semiotics and Information Science: We are interested in reasoning of inter-relationship interpretation between humans, informatin, and machines through the lense of sign theory.
  • Semantic Web and Linked Open Data: The semantics and linked relations of the linked data is powerful and effective. We feel extra motivated to explore the possibility of linked data and semantic web, both in theoretical and practical dimensions.


hese are some of the projects we actively participate in:

  • OSSF (OSSF Supports Software Freedom): OSSF is a major open source resource center and software repository serving Taiwan and worldwide.
  • iCAST & TWISC: TWISC (Taiwan Information Security Center) is an integrated effort to conduct research and development activities in information security in Taiwan. iCAST stands for “International Collaboration for Advancing Security Technology”.

Why the name "Guava"?

Guava trees are found in many tropical and subtropical regions. They are cultivated for their declicious fruits. In our lab we name many of our computer servers by fruit names. We feel that guava, being fertile by nature and diverse in its variety, is a nice name for this place.
