6 Conclusion
</SectionTitle>
    <Paragraph position="0"> Although SCNE is very common in written Chinese text, due to the lack of in-depth research, SCNE is a major source of errors in NER. This paper formulates the SCNE recognition within the source-channel model framework. Our experiments show very encouraging results: an F-score of 81.01% for single character location name recognition, an F-score of 68.02% for single character person name recognition. An alternative view of the SCNE recognition problem is to formulate it as a classification task. We construct two classifiers respectively based on maximum entropy model (ME) and vector space model (VSM), respectively.</Paragraph>
    <Paragraph position="1"> We compare all proposed approaches, showing that the source-channel model performs the best in most cases.</Paragraph>
