Various Markov models have been proposed to model individuals' mobility, i.e., the transitions between locations. Although these studies are able to show high predicting accuracy of individuals' next move, two basic assumptions of these studies, namely the stationarity of individuals' mobility sequence and the dependency of visiting the locations, have never been validated. Moreover, a famous recent...
Entering-tones are the tones which corresponding Chinese characters are ancient entering-tone characters. The entering tones are recognized using hybrid method which combines rule-based method with statistical method. The syllable which may possibly be an entering-tone or a non-entering tone is called ambiguity syllable. The non-ambiguity syllables can be recognized using rule-based method. The ambiguity...
In this work, an unsupervised statistical method for automatic correction of preposition errors using the Google n-gram data set is presented and compared to the state-of-the-art. We use the Google n-gram data set in a back-off fashion that increases the performance of the method. The method works automatically, does not require any human-annotated knowledge resources (e.g., ontologies) and can be...
One nodus existing in Chinese word segmentation is the ambiguity problem of which more than 85% are crossing ambiguity, therefore it is significant to decrease the error in dealing with the crossing ambiguity. Taking the advantage of the characteristics of the crossing ambiguity string, a novel method based on the mutual information and t-test difference is proposed to deal with the ambiguities in...
There are many connotative semantic features in Chinese which can help Chinese named entity recognition. Moreover, one of the important strongpoint of maximum entropy model is that it can syncretize features in different granularity and level. With that in mind, many Chinese named entity semantic knowledge bases were established by extracting information from corpus in this paper. However, because...
