HOMEWORK #2: SNePS II

Do Martins 2002, p. 212, #9, i.e.:

Represent the following paragraph in SNePS.

Since the passage is a connected paragraph, you should use a single network, but you can split it up into separate parts for ease of reading if you wish. However, make sure that, if you represent some concept with a node in one part of the network, you should represent that same concept with the same node if it reappears in another part of the network (that's part of what's called the "uniqueness principle").

You may use either (preferably) a graphical net (hand-drawn is fine) or SNePSUL code.

Anna knows that John bought a dog. The dog is a German Shepherd. John paid $300 for the dog. Anna also knows that Stu sold his dog. Anna believes that John bought Stu's dog.

Give the syntax and semantics of each case frame you use.
