Testing eg2B and WH Restrictions

Read Document 2X, and Document 2B.

  1. Follow the test procedure outlined in previous assignments and provide a comparable report of results. Use the command file parse in this directory, class2B. It calls upon the grammar eg2B.obg and its symbol table eg2B.sym. It also calls upon the dictionary wd2B.wdo.

    Test sentences are in sents2B.ocf. Edit the file of input directives, parse.inp as you wish. To parse the sentences in sents2B.ocf, type the command

    parse sents2B
    and return.

  2. Parse the following sentences with traces on WWH1, WWH2, and WWH3. Choose one instance of each restriction that shows it doing some work toward achieving a correct parse. Indicate where in the restriction significant tests are made.

    *SID=EGB 001.01X.02.001
    The tower which was discovered was built by Columbus .
    *SID=EGB 001.01X.02.002
    The tower which they discovered was built by Columbus is green .

    Note: When you create a file of sentences to be parsed, each sentence must be preceded by an SID line of the same form as above. The final period must be preceded by a space. The file name must end with the extension ".ocf", e.g. test.ocf.
