This paper reports a handful of experiments designed to test the feasibility of applying well-known partial parsing techniques to the problem of automatic data base update from an open-ended source of messages. and the feasiblity of automatically learning semantic knowledge from annotated examples. The challenges arise from the incompleteness of any lexicon, sentences that average over 20 words in length, and the lack of a complete semantics.
