We present a computer-assisted language learning (CALL) system that generates fill-in-the-blank items for preposition usage. The system takes a set of carrier sentences as input, chooses a preposition in each sentence as the key, and then automatically generates distractors. It personalizes item selection for the user in two ways. First, it logs items to which the user previously gave incorrect...

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 ...

Prepositions are an important vehicle for indicating semantic roles. Their meanings are difficult to analyze and they are often discarded in processing text. The Preposition Project is designed to provide a comprehensive database of preposition senses suitable for use in natural language processing applications. In the project, prepositions in the FrameNet corpus are disambiguated using a sense...

Linguistic data was collected via recording free speech, and interviewing with 30 (15 females, 15 males) illiterate Sistani language consultants of age 40–102 year...

In this paper we address these problems by presenting two evaluation methodologies, both based on a novel use ...
