extend grammar to handle lastbook_nomatch, usermodel_match, usermodel_nomatch

[arne-cl]

There are a few message blocks that pypolibox currently can't turn into an HLDS structure, since there is/are no corresponding rules/vocabulary in the OpenCCG grammar fragment we're using.

Have a look at lexicalize_messageblocks.py:

def lexicalize_lastbook_nomatch(lastbook_nomatch_message_block):
    r"""
    Im Gegensatz zum ersten / vorhergehenden / anderen Buch ____
    """
    raise NotImplementedError, "The grammar fragment can't handle lastbook non-matches, yet."

def lexicalize_usermodel_match(usermodel_match_message_block):
    r"""erfüllt Anforderungen / entspricht ihren Wünschen"""
    raise NotImplementedError, "The grammar fragment can't handle usermodel matches, yet."

def lexicalize_usermodel_nomatch(usermodel_nomatch_message_block):
    r"""erfüllt (leider) Anforderungen nicht / entspricht nicht ihren
    Wünschen"""
    raise NotImplementedError, "The grammar fragment can't handle usermodel non-matches, yet."

As an example, let's ask pypolibox for a book about parsing:

pypolibox --keywords parsing

[...]

The id message block can be realized as follows:

„ Computational_Linguistics._An_Introduction. “ von Ralph Grishman ist im Jahr 1986 erschienen .
Ralph Grishmans „ Computational_Linguistics._An_Introduction. “ beinhaltet keine Code-Beispiele .
das Buch richtet sich an Anfänger .
Ralph Grishmans „ Computational_Linguistics._An_Introduction. “ beinhaltet Übungen .
das Buch von Ralph Grishman umfasst 193 Seiten .

The grammar fragment can't handle usermodel matches, yet.
The message block contains these messages:
[ *msgType*           = 'usermodel_match'                                          ]
[ *reference_authors* = (frozenset(['Ralph Grishman']), 'neutral')                 ]
[ *reference_title*   = ('Computational Linguistics. An Introduction.', 'neutral') ]
[ keywords            = (frozenset(['parsing']), 'positive')                       ] 

In this case, pypolibox will generate the ID message block for a matching book, but cannot express the usermodel_match message block (something like "das Buch behandelt das Thema Parsing und entspricht damit ihren Wünschen").
