Task 1:

Add lexicon entries for "she", "her", "help", "receives", "shouts", (to) "run", they.

Task 2:

Add grammar rules so that the following two sentences are correctly recognized: "she shouts" and "she receives help". This time, "her shouts" should not be recognized by the grammar; in addition, "she run" must not be recognized by the grammar.

Solution from last week:

noun_verb_rule       => a sentence phrase with two children: a noun word + a verb word.
verbphrase_rule     => a verb phrase with two children: a verb word + a noun word.
noun_verbphrase_rule => a sentence phrase with two children: a noun word + a verb phrase.

Better solution:

sentence_rule       => a sentence phrase with two children: a noun word (nominative) + a verbal sign (finite).
verbphrase_rule     => a verb phrase with two children: a verb word (finite) + a noun word (accusative).

Task 4:

Delete the three rules and reimplement them such that only two rules are needed. The same set of phrases should be correctly recognized and/or rejected.

Task 5:

Add "gives" and "support" to the lexicon and a rule to analyze the sentence: "she gives her support".

Task 6:

Add "the" to the lexicon and a rule to analyze the phrase: "the help". "She receives the help." should be correctly recognized by the grammar.

   case   
      acc   
      nom   
.

Task:

Add the same lexicon entries and rules. This time, "she receives", "she shouts help" should not be recognized by the grammar!

HOMEWORK: Grammar 3 (Politics)

Task 1:

Based on today's news [1], add the following German entries to your lexicon: "soeder", "seehofer", "beerbt", "ihn", "beerben", "kommt", "bleibt".

Task 2:

Make use of the COMPS attribute, and write two grammar rules such that the following phrases are correctly recognized: "soeder beerbt seehofer", "soeder beerbt ihn", "soeder bleibt", "soeder kommt". (The verbs need so specify the types of objects they typically combine with.)

The following phrases must not be recognized: "soeder bleibt ihn", "ihn kommt", "soeder beerben seehofer".

Task 3:

Add new lexicon entries and a ditransitive rule so as to recognize the phrase "soeder macht merkel probleme". Note that a ditransitive verb and an appropriate additional rule is needed.

Task 4:

Add a new rule for noun phrases: "der minister macht ihr probleme".
