「Python实战项目」针对医疗数据进行命名实体识别 pythonhttpjava 命名实体识别(Named Entity Recognition,简称NER),又称作“专名识别”,是指识别文本中具有特定意义的实体,主要包括人名、地名、机构名、专有名词等。通常包括两部分:(1)实体边界识别;(2) 确定实体类别(人名、地名、机构名或其他)。

The idea of Named Entity Recognition is to identify and categorized hard designators like Names, Locations, Time, medical terms, and temporal expressions from text. We conduct experiment using NLTK-NER, Stanford 3-Class NER, Stanford 4-Class NER and Stanford 7-Class NER model to extract Named ...
