چکیده
This paper describes our approach to tackling the task of Technical Trend Map Creation as posed in NTCIR-8. The basic method is Conditional Random Fields, which is considered as the most advanced method in Named Entity Recognition. In order to improve the performance, we further resort a tag modification approach and pattern-based method. Our system performed competitively, achieving the top F-measure among participants in the formal run.
