Voice, letters, papers, prints, books, libraries, photos, movies, broadcasts, computers, artificial intelligence, data base, and networks are media of our message created through human history. Now, numerous messages come and go on the Internet. Those messages are sent and received, archived, retrieved, and transformed. Then “places” of the messages are constructed with human thought and communication. It can be called Knowledge Spaces.
