Functional Requirements

The NLP unit should conform to the following requirements specification:

1. Semantic output - the NLP module must receive phrase data and generate the semantic parse tree for that input.
2. Parsing algorithm - the most efficient parsing algorithm applicable shall be used in order to produce the semantics from the textual input.
3. Pragmatic output - using the semantics of the original input, a pragmatic response should be generated.
4. Error handling - the modules should deal with erroneous, unparsable or pragmatically incorrect inputs by reporting an appropriate error message.
