I think one of the questions that would first leap to mind for many people on this list is what language pairs are you interested in, and what parallel / comparable corpora do you have available?
If you have parallel corpora, there are lots of methods for extracting term pairs that are relatively readily available nowadays (e.g., we have some support for this in SemanticVectors, see http://code.google.com/p/semanticvectors/wiki/BilingualModels).
In general, over recent decades many approaches have changed from looking at questions like "give me a list of all English verbs and their conjugations" to questions like "given a sample of the data you're interested in working with, give me a list of prevalent English verbs and their conjugations".
Best wishes, Dominic
