This paper describes a hybrid symbolic/connectionist system which combines symbolic and connectionist techniques for the structural interpretation of noun phrases. Using coordination (grammatical structures with conjunctions like "and") as a representative problem for a whole class of attachment problems, we describe a system which integrates syntactic and semantic knowledge for parsing "real world" text from a scientific technical corpus. Our hybrid model consists of a symbolic chart parser for parsing noun phrases, a symbolic preference module for semantic expectations, and a connectionist backpropagation network for semantic coordination relationships. We show that a symbolic syntactic parser and a connectionist semantic memory model can interact for resolving coordination problems.
