   The more usual approach is to use a formal meaning representation,   
   first order predicate calculus is a good example based on first order   
   logic and lambda calculus. For instance, if you have the phrase "a red   
   cat" you would get something like Ex Cat(x) & HasColor(x, red).   
      
   You should start by finding out exactly what you have to represent. Do   
   you need to represent time or belief, then you need temporal or modal   
   logic. Will all the sentences concern a certain domain? Then you can   
   use a domain ontology to specify useful categories. Will some events   
   be very common? For example, if all the sentences are concerned with   
   making a reservation, then you know which aspect to represent and how   
   to store them in a database.
