Abstract

In this paper we describe an integrated ap-proach for named entity recognition and dis-ambiguation in Chinese. The proposed method relies on named entity recognition (NER), en-tity linking and document clustering models. Different from other tasks of named entities, both classification and clustering are consid-ered in our models. After segmentation, in-formation extraction and indexing in the pre-processing step, the test names in the docu-ments would be judged to be common words or named entities based on hidden Markov model (HMM). And then each predicted entity should be linked to the category in the given knowledge base (KB) according to the charac-ter attributes and keywords. Finally, the named entities which have no reference in KB would be clustered into a new category based on sin-gular value decomposition (SVD). An imple-mentation of our presented models is de-scribed, along with experiments and evalua-tion results on the Second CIPS-SIGHAN Joint Conference on Chinese Language Pro-cessing Bakeoff (Bakeoff-2012). Named entity recognition F-measure reaches up to 76.67% and named entity disambiguation F-measure up to 69.47% within the test set of 32 names.
