文本数据标注工具doccano【介绍最详细的一遍文章】

doccano介绍：

doccano是一个开源文本标注工具。 它提供了文本分类，序列标注和序列到序列的标注功能。 因此，您可以为情绪分析，命名实体识别，文本摘要等创建标记数据。 只需创建项目，上传数据并开始标注。

总结下来就3步，上传数据，标注，下载带有标签的数据。

官网：http://doccano.herokuapp.com/

命名实体识别

第一个演示是序列标记任务之一，命名实体识别。 您只需选择文本跨度并对其进行标注即可。 由于doccano支持快捷键，因此您可以快速标注文本跨度。

情感分析

第二个演示是文本分类任务之一，主题分类。 由于可能有多个类别，因此您可以标注多个标签。

机器翻译

最终演示是序列任务，机器翻译的序列之一。 由于序列任务的顺序可能不止一个，因此您可以创建多个响应。

doccano特性

• Collaborative annotation（合作标注：可以进行多人合作，分配标注任务。）
• Multi-language support（支持多种语言）
• Mobile support（支持移动）
• Emoji  support（支持标签）
• Dark theme（主题）
• RESTful API（RestFul风格）

安装doccano

安装：我使用的安装方式是docker镜像：

【不知道docker是什么？docker有什么用？docker的学习资料？docker的相关资料稍后会整理成博文，链接将贴在此处；敬请期待】

拉取doccano的Docker镜像  

 docker pull chakkiworks/doccano

运行：将Docker镜像作为Container运行

docker run -d --rm --name doccano \
-e "ADMIN_USERNAME=admin" \
-e "[email protected]" \
-e "ADMIN_PASSWORD=password" \
-p 8000:8000 \
chakkiworks/doccano

其中可自定义用户名和密码并设置邮箱：

用户名：ADMIN_USERNAME=yourself_username

邮箱：ADMIN_EMAIL=yourself_email

密码：ADMIN_PASSWORD=yourself_password

登录：

现在，打开Web浏览器并转到http://IP:8000/login/。 你应该看到登录界面：

创建项目：

现在，尝试使用您在上一步中创建的超级用户帐户登录。 您应该看到doccano项目列表页面：

注意：只有超级管理员才能创建项目，上面的运行实际上就是创建超级管理员账号

 尚未创建任何项目。 要创建项目，请确保您已进入项目列表页面并选择“创建项目”按钮。 您应该看到以下屏幕：

在此步骤中，您可以选择四种项目类型：文本分类，序列标记，序列到序列和语言转文字。 您应该选择符合您目的的类型。

创建好项目后会跳转到导入数据页【以文本分类为例】：

创建项目后，您将看到“导入数据”页面，或单击导航栏中的“导入数据”按钮。 您应该看到以下屏幕：

导入数据后【所有页面相关介绍】：

注册成功后不能登录【第一次登录时不能直接登录，第二次可以使用用户名和密码登录】，需通过后台日志生成的访问路径进行进入：

#查找到对应的containerID
[root@docker ~]# docker ps
#通过containerID查看docker容器运行日志；格式：docker logs containerID。；例如我的containerID为7c5250576e3e6d133006b80610a4c4f03896e36bd016e8c3ad0e4e4ddc8e4834
