The Czech Minister of Transportation, Jan Strasky, proposed on
Saturday, January 8 that the State buy back the shares (just less than
20%) held by Air France and the Reserve Bank/deposit accounts in the
national airline, CSA, so that they could be sold "to another partner,
probably a bank."

Issues:

- "buy back" can't be found.

- Process:

1. Filtering the subj, obj, main (POS V) from the output.
2. Assign semantic roles on subj, obj
3. Find a concept on (POS V)
