Chinese nested named entity recognition
WebChinese nested named entity recognition. To approach this task, we first employ the logistic regression model to extract multi-level entity morphemes from an entity-tagged corpus, and thus explore multiple features, particularly entity-level morphological cues for Chinese nested named entity recognition under the framework of conditional random ...
