CorpusForFun is an innovative attempt to rethink corpora. In keeping with the ever growing big data and social networks, modern corpora are supposed to go from static to dynamic, providing information that reflects the society, time and space, and even explore new dimensions such as stances, trends of thought and flows of emotion. CorpusForFun redefines Chinese words with dynamic data by capturing multi-word expressions, discovering temporal information, attending to connectivity between lexical units and finally, anchoring the units to a time frame. Corpora are no fossils from the ancient times, but belong to the present and the future, as one means to look at the modern society.
