Corpus Based PP Attachment Ambiguity Resolution with a Semantic Dictionary
This paper deals with two important ambiguities of natural language: prepositional phrase attachment and word sense ambiguity. We propose a new supervised learning method for PPattachment based on a semantically tagged corpus. Because any sufficiently big sense-tagged corpus does not exist, we also propose a new unsupervised context based word sense disambiguation algorithm which amends the tra...
متن کاملRelative clause attachment ambiguity resolution in Persian
The present study seeks to find the way Persian native speakers resolve relative clause attachment ambiguities in sentences containing a complex NP of the type NP of NP followed by a relative clause (RC). Previous off-line studies have found a preference for high attachment in the present study, an on-line technique was used to help identify the nature of this process. Persian speakers were pre...
متن کاملPP Attachment Ambiguity Resolution with Corpus-Based Pattern Distributions and Lexical Signaturese
We propose a method mixing unsupervised learning of lexical pattern frequencies with semantic information which aims at improving the resolution of PP attachment ambiguity. Using the output of a robust parser, i.e. the set of all possible attachments for a given sentence, we query the Web and obtain statistical information about the frequencies of the attachments distributions as well as lexica...
متن کاملA Nearest-Neighbor Method for Resolving PP-Attachment Ambiguity
We present a nearest-neighbor algorithm for resolving prepositional phrase attachment ambiguities. Its performance is significantly higher than previous corpus-based methods for PP-attachment that do not rely on manually constructed knowledge bases. We will also show that the PP-attachment task provides a way to evaluate methods for computing distributional word similarities. Our experiments in...
متن کاملA Nearest-Neighbor Method for Resolving PP-Attachment Ambiguity
We present a nearest-neighbor algorithm for resolving prepositional phrase attachment ambiguities. Its performance is significantly higher than previous methods that were tested on the same data set. We will also show that the PP-attachment task provides a way to evaluate measures of distributional word similarities. Our experiments indicate that the cosine of pointwise mutual information vecto...
