WikiSym is an international symposium on wikis and open collaborative techniques, mainly focused on wiki research and practice. Back in 2007, we coined the term "self-aware" wiki systems in our paper submitted to the WikiSym '07, fostering the idea that the integration of Natural Language Processing (NLP) techniques within wiki systems allows the wiki systems to read, understand, transform, and even write their own content, as well as supporting their users in information analysis and content development. Now after a few years, we have realized this idea through an open service-oriented architecture.
