The paper describes an experiment in detecting a specific type of multiword expressions in Russian, namely expressions starting with a preposition. This covers not only prepositional phrases proper, but also fixed syntactic constructions like v techenie (‘in the course of’). First, we collect lists of such constructions in a corpus of 50 mln words using a simple mechanism that combines statisti...

Converting information contained in natural language clinical text into computer-amenable structured representations can automate many clinical applications. As a step towards that goal, we present a method which could help in converting novel clinical phrases into new expressions in SNOMED CT, a standard clinical terminology. Since expressions in SNOMED CT are written in terms of their relatio...

In gapping, topical indefinites as well as wh-phrases can contrast with surface-identical antecedents if the contrast involved is the first of the two (or more) contrast pairs in the gapping coordination. This is not possible for most other types of expressions. We argue that both topical indefinites and wh-phrases introduce a discourse referent with a fixed address, on the basis of which refer...

The term fixed expression refers to a formally quite heterogeneous group of expressions, such as adjective-noun collocations (e.g. heavy smoker), prepositional expressions (e.g. in spite of), verbal expressions (e.g. break the ice), dual expressions (e.g. black and white), foreign phrases (e.g. per capita), etc. The properties that unite them are that they consist of more than one word and are ...

This paper describes in outline a method for translating Japanese temporal expressions into English. We argue that temporal expressions form a special subset of language that is best handled as a special module in machine translation. The paper deals with problems of lexical idiosyncrasy as well as the choice of articles and prepositions within temporal expressions. In addition temporal express...

This paper is concerned with the identification of two semantically close categories – temporal locating adverbials and time-denoting expressions. The dividing line between these categories is difficult to draw, inasmuch as there are several phrases that occur with the same surface form in the typical contexts of both of them (e.g. in adverbial position and as the complement of verbs like to da...
