java - 为什么斯坦福 CoreNLP 服务器将命名实体拆分为单个标记？

Question

我使用此命令来发布数据(从斯坦福网站复制一些意大利面):

wget --post-data 'Barack Obama was President of the United States of America in 2016' 'localhost:9000/?properties={"annotators": "ner", "outputFormat": "json"}' -O out.json

响应如下所示:

            }
        }]
    }]
}

我做错了什么吗？我有 Java 客户端代码，至少可以将 Barack Obama 和 United States of America 识别为完整的 NER，但使用该服务似乎会单独处理每个 token 。有什么想法吗？

您应该将 entitymentions 注释器添加到注释器列表中。
