客户端

使用方式

方式一：Python库使用

示例如下： 

fromltp_serverimportClientif__name__=='__main__':client=Client()texts=["乔丹是一位出生在纽约的美国职业篮球运动员。"]print(client.sent_split(texts))print(client.seg(texts))print(client.pos(texts))print(client.ner(texts))print(client.srl(texts))print(client.dep(texts))print(client.sdp(texts))print(client.sdpg(texts))

请求结果：
