| Abstract: | In recent years,there are a lot of research achievements in the field of NER(name entity recognition),while PNER(product named entity recognition) is just starting.With the rapid development of e-commerce,PNER becomes one of the key techniques of intelligent e-commerce.In the view of supporting domain ontology to PNER,a method of PNER was proposed,which combined CRF(conditional random field) model with domain ontology as a semantic feature besides word and part-of-speech features.Experiments were conducted ... |
