1.   Give two reasons for including a representation of semantic information in a grammar.

2.   In particular, dictionary definitions and co-occurrence statistics have been identified as valuable sources of semantic information.

3.   Researchers within computational lexicography have attempted to exploit this style to extract semantic information.

4.   Useful semantic information therefore facilitates the incidence of meaningful strong overlaps in normal text.

5.   They aim to generalise from the relational model by capturing as much semantic information from an application domain as possible.
