Grammar Writing: Week 6

Howework assignment, due Monday November 27th:

The Week 5 grammar worked pretty well, but wrongly allowed intransitive verbs to occur with NPs and transitive verbs without NPs. This problem can be solved by giving every sign a COMPS list which encodes what kinds of signs (if any) a verb needs to have to be complete on its righthand side. This is the purpose of the Week 6 grammar.

Task 1

In DesktopTrale, develop a grammar consisting of the following components: (see below), i.) a type hierarchy, ii.) lexical entries, iii.) rules.
Save the grammar using this file name: "week6". (The program should produce the "week6.zip" file.)

Task 2

The grammar should be uploaded and tested on 
[1]
(use your assigned port number!)

The Type Hierarchy

1. Import the type hierarchy from Week 5.
2. Add the attribute COMPS with value list to the type syntax.

Lexical entries

From here on, all lexical entries should contain information about the word's COMPS list, i.e. the list with the kinds of signs that the word needs to combine with to its right to form a complete phrase. COMPS lists in English are either empty or contain 1-2 signs, separated by commas. Do not require complements to be phrases or words, since complements can be both!

In order to enter a sign into a COMPS list, click in the middle of the list. Usually it is best to put the definition of each complement in parentheses, e.g.

1. <(sign, ...)> = a single complement
2. <(sign, ...), (sign, ...)> = two complements

Phrases

Since the feature COMPS is defined for all signs, like every word, every phrase needs to have a COMPS value.

Verbs

likes
smokes

Nouns

bo
lilly
her
she

Rules
