Due to the information explosion, web IE (information extraction) comes into being. Though people get used to inquiring information by 2-D text reading in traditional way, browsing words is not enough for users' acquiring knowledge today. Actually, people find that most information is geo-referenced especially after Digital Earth (DE) is proposed, which makes people can get information in a 3-D environment. Google Earth (GE) is such kind of one important product of DE. In order to make people get more information from GE's limited information recourses, we utilize IE to extract needed information from semi-structured web page biographies and map the information to corresponding places on GE. Also, how people read traditional 2-D text in a 3-D environment is studied. How the previous text biography is vividly presented on ‘our planet’ like a man's life trace is introduced in our work.
