#Sentence TEXT 010 As CSA faces serious difficulties, the Czechs offer
to buy back the French shares in their national airline

------------------------------------------------

Comments:

For "faces serious difficulties" I chose the CONFRONT concept from
Omega.  Then to assign Semantic roles, I chose the "predicament" frame
from Framenet, which has an experiencer and a situation.

CZECH in Omega is defined as a person from the Czech republic, but of
course "the czechs" in this sentence are the representatives of the
Czech government or something like that. 

"buy it back" means that they owned it once before.  That isn't
exactly captured by BUY$VERB.

"the French shares" is probably a possession relation, but we can also
infer that the French are the sellers in the buying action.  Not going
to touch that now.
