Review Questions on Natural Language Processing
Topics: Features and Augmented Grammars; Semantics and Logical Form
This is a voluntary quiz to help you decide whether you have
understood some of the major concepts from this topic. It carries
- The subcat feature for verbs may take values like none,
np, vp:inf, and np_vp:ing. Define each of these
and find example of each, either without looking at the lecture notes,
or after looking at the lecture notes but giving examples that are
different from the ones the lecture notes.
- Write an augmented grammar rule for a VP whose head verb subcategorises
- What can the head subconstituent of a noun phrase be?
- Using the extended chart-parsing technique illustrated in lectures,
parse the sentence Time flies, and show why the ill-formed
sentence *Time fly cannot be parsed. Assume grammar rules
S → NP VP, VP → V, NP → N, and use the agr
feature. Time is an N and fly and flies are Vs.
- What are the components of the logical form language described in lectures?
- From what sentence might the following logical form come?
| ||theme[the(P1, pizza1>)],|
| ||at-loc[a(R1, restaurant1>)])|
- What is a speech act?
- Write down the logical form for Who gave you the flu?
