After the prerequisites are now explained, it is time to start with the actual syntax-driven semantic analysis. It will be shown with an example provided by Jurafsky. In the following expressions $x$ symbolizes a thing and $e$ symbolizes a state or attribute. Assume the sentence \textit{Every restaurant closed}. ``The target representation for this example should be the following''\cite[p.~621]{Jurafsky2009}.

After these steps we end up with the target representation, as announced earlier. After these steps we end up with the target representation, as announced earlier.
This example is just one of many, but it shows how semantic meaning can be attached to syntactic components. Furthermore it should be clear now, how semantic analysis in a syntax-driven approach works. \subsubsection*{Application}
\label{subSub:applicationSem}
This first shows the process of retrieving the meaning representation. But before the meaning representation can be calculated, the semantic attachments have to be assigned. Therefore the previously introduced example that has already been used for the syntactic parsing, will now be used to show the whole process of semantic analysis, including finding the semantic attachments.
