您好，谢谢您关注我的问题（关于ICE—GB中的face-to-face-converstion）， 我从corpus map 中看到的说话者身份信息是这样的：

speakers per text: 2
speaker age: <all>
speaker gender: m
speaker education: <all>
speaker role: (这里是空白，却正是我最需要的)
下边是text category, date, place, 这些信息都有

所以冒昧写信弱弱地请教一下，您提供的以下这种详细信息是怎么找到的：
Text category: Private: Direct conversation
Place: Middlesex Poytechnic
Date;1991
Gender: male
Education: university
Forename:Sam
Age: 26-45
Occupation: teacher

Speaker B:
Text category: Private: Direct conversation
Place: Middlesex Poytechnic
Date:1991
Gender: male
Education: secondary
Age: 18-25
Occupation: student

麻烦了，不胜感谢！！
