Web-Based Model for Disambiguation of Prepositional Phrase Usage

摘要

We explore some Web-based methods to differentiate strings of words corresponding to Spanish prepositional phrases that can perform either as a regular prepositional phrase or as idiomatic prepositional phrase. The type of these Spanish prepositional phrases is preposition-nominal phrase-preposition (P-NP-P), for example: por medio de 'by means of', a fin de 'in order to', con respecto a 'with respect to'. We propose an unsupervised method that verifies linguistics properties of idiomatic prepositional phrases. Results are presented with the method applied to newspaper sentences.
