Adding environments as first-class entities to a language can greatly enhance its expressiveness. But first-class environments rely on identifiers, the syntax of variables, and thus do not mesh well with lexically-scoped languages. We present first-class extents as an alternative. First-class extents are founded upon lexical variables with dynamic extent. They are defined directly on the variab...

Multi-word lexical units are a typical feature of specialized dictionaries, in particular monolingual and bilingual maritime dictionaries. The paper studies the concept of the multi-word lexical unit and considers the similarities and differences of their selection and presentation in monolingual and bilingual maritime dictionaries. The work analyses such issues as the classification of multi-w...

Semantic Interoperability is a major issue for National Spatial data Infrastructures (NSDIs) and mapping across heterogeneous databases is essential for such interoperability. Mapping of schemas based on ontology mapping provides opportunities for semantic translation of schemas elements and hence for database queries across heterogeneous sources. Such semantics based mappings are usually human...

This study compares lexical retrieval amongst monolinguals and intermediate bilinguals and advanced bilinguals. It also investigates the possible effects of their language learning strategies on their respective lexical retrieval advantage. The study used a mixed methods design and the groups consisted of 20 Persian near-monolinguals, 20 Persian-English intermediate level bilinguals, and 20 Per...

We present a study that investigates that factors that determine what makes a good lexical substitution. We begin by observing that there is a correlation between the corpus frequency of words and the number of WordNet senses they have, and hypothesise that readers might prefer common, but more ambiguous words over less ambiguous but also less common ones. We identify four properties of a word ...

Sub-categorized arguments introduced by the French preposition pour has been under-studied in previous work, as can be seen from the incompleteness of existing lexical-syntactic resources in that regard. In this paper, we briefly introduce the various types of sub-categorization in pour, which are to be distinguished from occurrences of pour as a discourse connective. We describe how we added a...
