Feature engineering and post-processing for temporal expression recognition using conditional random fields
Sisay Fissaha Adafre, Maarten de Rijke · 2005
We present the results of feature engineering and post-processing experiments conducted on a temporal expression recognition task. The former explores the use of different kinds of tagging schemes and of exploiting a list of core temporal expressions during training. The latter is concerned with the use of this list for post-processing the output of a system based on conditional random fields.
