In this chapter we have seen how networks can be constructed that link different levels of concepts. In Chapter 7 we saw how organizational trees can be constructed that organize knowledge about a particular topic (see Figures 7.5 and 7.6). Create a tree that represents the material in this chapter by linking together things that are related. How is this tree similar to or different from the semantic network in Figure 9.12? Is your tree hierarchical? What information does it contain about each concept? L01
