Re: Lexico-Syntactic Patterns

Hi Dagmar,

I was wondering what exactly you mean with lexico-syntactic patterns. In *
lemon* we certainly had frames that could induce ontological properties,
e.g.,

"X is the capital of Y" => X onto:capital Y

But these are fairly standard and similar to other semantic role/syntactic
frames (and should clearly be a part of our work in this group).

On the other hand, we have Hearst patterns like

"X such as Y" => Y rdfs:subClassOf X

However, these kind of patterns would not traditionally belong in the
lexicon as they do not represent a direct mapping, i.e.,

   1. It is difficult to say when "such as" actually indicates a subclass
   relation (i.e., it is error prone)
   2. It was not the intention of the speaker to use "such as" to express a
   subclass relation

Of course, it may be interesting to consider a representation of something
like this in the group. Could you give some examples of the kind of mapping
you are interested in, and how they might be represented (relative to an
existing model like lemon).

Regards,
John
