Summary
This chapter looks at some problems which face the builder of MT systems. We charac-
terized them as problems of ambiguity (lexical and syntactic) and problems of lexical and
structural mismatches. We saw how different types of linguistic and non-linguistic knowl-
edge are necessary to resolve problems of ambiguity, and in the next chapter we examine
in more detail how to represent this knowledge. In this chapter we discussed instances of
lexical and structural mismatches and the problem of non-compositionality (as exempli-
fied by idioms and collocations) and looked at some strategies for dealing with them in
MT systems.
