For pre-processing, we perform sentence boundary detection and Chunking derived from Stanford parser (Klein and Manning, 2003), Named Entity Recognition using a SVM based system trained and tested on ACE 2005 with 92.5(P) 84.3(R) 88.2(F), and coreference resolution using a SVM based coreference resolver trained and tested on ACE 2005 with 79.5%(P), 66.7%(R) and 72.5%(F).
our experiment results show that both proposed knowledge sources are effective for entity linking.
