(a) Use the following text to derive distributions for rat and chased. Use a five-word window, including open- and closed- class words, ignore case, punctuation and sentence boundaries and weight contexts by frequency. The cat chased a rat. A big rat chased the big dog. [4 marks] (b) Show unlabelled dependency links for each sentence and give distributions for rat and chased using contexts derived from single dependency links. [5 marks] (c) In general, what type of differences will arise in distributions if dependency links are used instead of word windows as context? [4 marks] (d) Outline one or more experiments to determine whether distributional informa- tion could be used in conjunction with a syntactic parser to help disambiguate prepositional phrase attachment ambiguities.
