Homework Assignment (Due November 5th)

Task 1
In DesktopTrale, model the following type hierarchy. Make sure to start with topmost types. Add features only after the corresponding types have been specified.
Don't forget to finally update the type hierarchy to make the changes effective. No spaces, no upper case letters, only underscore characters are allowed !

Task 2
Save the Type Hierarchy both in XML and in Trale format under the name "02_SVN".

 Task 3
Add lexical entries for "Lilly", "John", "cigarettes", "books", "reads", "cars", "smokes", "drives", "gives", and "dances". (Use lowercase letters also for the proper names!)

Task 4
* Add a rule called "verb_noun_rule" with two child nodes, which combines a verb followed by a noun to form a sentence node. (e.g., for "smokes cigarettes").
* Add a rule called "noun_verb_rule" with two child nodes, which combines a noun followed by a verb to form a sentence node. (e.g., for "John smokes.")
* Add a rule called "verb_noun_noun_rule" with three child nodes, which combines a verb followed by two nouns to form a sentence node and provide an example for a phrase which could be recognized from the list of available lexical entries.

Note: Tags (boxed numbers representing child nodes) should be moved into the daughters list (DTRS) of the parent node. This can be accomplished by drag-and-drop (left click on the tag and move it inbetween the brackets), OR by keeping CTRL/(STRG) pressed + right click on the DTRS list and then selecting Add Tag to list.

 Task 5
Save the grammar as XML and Trale under the name "02_SVN_ready_for_testing".
