Exploiting the WWW as a corpus to resolve PP attachment ambiguities
نویسنده
چکیده
Finding the correct attachment site for prepositional phrases (PPs) is one of the hardest problems when parsing natural languages. An English sentence consisting of a subject, a verb, and a nominal object followed by a prepositional phrase is a priori ambiguous. The PP in sentence 1 is a noun attribute and needs to be attached to the noun, but the PP in 2 is an adverbial and thus part of the verb phrase.

Scaling up. Using the WWW to Resolve PP Attachment Ambiguities
We have developed a method to resolve ambiguities in prepositional phrase (PP) attachment in German. We measure on the one hand the cooccurrence strength between nouns (N) and prepositions (P) and on the other hand between verbs (V) and prepositions. The competing values of N+P versus V+P are used to decide whether to attach a prepositional phrase to the noun or to the verb. We calculate the co...

This paper reports on two studies investigating children’s and adults’ processing of sentences containing ambiguity of prepositional phrase (PP) attachment. Study 1 used corpus data to investigate whether cues argued to be used by adults to resolve PP-attachment ambiguities are available in child-directed speech. Study 2 was an on-line reaction time study investigating the role of lexical and r...
متن کاملThe Automatic Resolution of Prepositional Phrase - Attachment Ambiguities in German
Any computer system for natural language processing has to struggle with the problem of ambiguities. If the system is meant to extract precise information from a text, these ambiguities must be resolved. One of the most frequent ambiguities arises from the attachment of prepositional phrases (PPs). A PP that follows a noun can be attached to the noun or to the verb. In this book we propose a me...
متن کاملUsing Bilingual Chinese-English Word Alignments to Resolve PP-Attachment Ambiguity in English
Errors in English parse trees impact the quality of syntax-based MT systems trained using those parses. Frequent sources of error for English parsers include PP-attachment ambiguity, NP-bracketing ambiguity, and coordination ambiguity. Not all ambiguities are preserved across languages. We examine a common type of ambiguity in English that is not preserved in Chinese: given a sequence “VP NP PP...
