This paper proposed a method for Unknown Words Identification (UWI) based on repeats. To identify Unknown words with reliable theory, we put forward a formal model for the process of UWI, which can give directions on the selection of features used in UWI in theory. For the formal model, we propose employing Conditional Random Fields model (CRF) as statistical frame to resolve it. Under the statistical...
Part-of-speech (POS) guessing of unknown words is an essential phase in the process of unknown words identification. This paper applies combined features (namely, both external and internal features) in POS guessing of Chinese unknown words, under conditional random field model (CRF). For acquiring high-precision of POS guessing, this paper puts forward a method of integrating Chinese radical, as...
