Constructopedia is an intuitive, efficient way to index, display, and browse encyclopedic knowledge bases. It uses a multidimensional matrix to aggregate and display hyperlinked materials by three index variables:
a) subject matter, and b) level of difficulty, along the axis of c) a validated universal construct*.
Constructive surfing is a browsing method that uses “universal constructs” as a connecting tissue to link knowledge across all domains of human knowledge at the most appropriate level of difficulty for each user.
