4.4 Looking Up the Lexicon
In this section we look at the lexicon. In a lexical lookup, the syntax component needs to find the syntactic category for a given input token, while the semantic component has to be provided with the associated meaning representation. Our strategy will again be to factor out as much as possible of the semantic side, as this side is what will change with different formalisms.
Up to now, we've been focussing on the upper half of our diagram, the part where words (and meanings) are combined. Let's now focus on the lower half, where words and meanings come from: Let's look at the lexicon. In a lexical lookup, the syntax component needs to find the syntactic category for a given input token, while the semantic component has to be provided with the associated meaning representation. Our strategy will again be to factor out as much as possible of the semantic side, as this side is what will change with different formalisms.
