This paper investigates the connection between temporal logic and the semantics of some temporal expressions in English. Specii-cally, we show how the meanings of English temporal preposition-phrases can be expressed as modal operators in an interval-based temporal logic which we call ETL0. We show how cascaded temporal preposition phrases and temporal preposition phrases with complex complemen...

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...

Prepositions are often considered to have too little semantic content or be too polysemous to warrant a proper semantic description. We illustrate the suitability of distributional similarity methods for analysing preposition semantics by way of an inter-preposition similarity task, and make the claim that any semantic account of preposition semantics must be partially conditioned on valence.

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...

Prepositions are highly polysemous. Yet, little effort has been spent to develop languagespecific annotation schemata for preposition senses to systematically represent and analyze the polysemy of prepositions in large corpora. In this paper, we present an annotation schema for preposition senses in German. The annotation schema includes a hierarchical taxonomy and also allows multiple annotati...

What these examples illustrate is that a particular Trajector (TR) can, in conjunction with a particular Landmark (LM), affect the interpretation of a preposition. On one hand, the interpretation ascribed to the sentence in (1) is that the LM, the bowl, contains or surrounds the TR, the fruit. On the other hand, in (2) the conventional interpretation is that the TR, the crack, constitutes a fla...
