Natural languages are full of word collocations that frequently co-occur and correspond to arbitrary word usages. They appear in both technical and non-technical textual corpora and often have specific significance in individual contexts. Accurately retrieving and identifying collocations from a given corpus in an unsupervised manner is imperative to understanding and automatically generating t...

Recognition of Multi-word Expressions (MWEs) and their relative compositionality are crucial to Natural Language Processing. Various statistical techniques have been proposed to recognize MWEs. In this paper, we integrate all the existing statistical features and investigate a range of classifiers for their suitability for recognizing the non-compositional Verb-Noun (V-N) collocations. In the t...

in different linguistic studies, usually only one type of collocations has been investigated and in the classifications that have been introduced for different types of collocations, just formal and grammatical properties of the words within collocations have been mentioned. this study, for the first time, introduces eight criteria such as pivot word, feature percolation and separability for de...

Collocations are notoriously difficult for non-native speakers to translate, primarily because they are opaque and can not be translated on a word by word basis. We describe a program named Champollion which, given a pair of parallel corpora in two different languages, automatically produces translations of an input list of collocations. Our goal is to provide a tool to compile bilingual lexica...

We describe a method to automatically discover translation collocations from a bilingual corpus and how these improve a machine translation system. The process of inference of collocations is iterative: an alignment is used to derive an initial set of collocations, these are used in turn to improve the alignment and this new alignment is used to generate new collocations. This process is repeat...

Collocations are one of the areas generally considered problematic for EFL learners. Iranian learners of English like other EFL learners face various problems in producing oral collocations.  An analysis of learners' spoken interlanguage both indicates the scope of the problem and the necessity to spend more time and energy by learners on mastering collocations. The present study specifically f...

Lewis (1993) recognized significance of word combinations including collocations by presenting lexical approach. Because of the crucial role of collocation in vocabulary acquisition, this research set out to evaluate the rate of collocations in Iranian EFL learners' writing production across L1 and L2. In addition, L1 interference with L2 collocational use in the learner' writing samples was st...

Abstract The congruency effect—that is, faster and more accurate processing of congruent multiword units, has been demonstrated in multiple studies. It is still unclear, however, what its underlying mechanism how may interact with other factors. Using an acceptability judgement task, this study examined the effect immersive (Experiment 1) nonimmersive 2) L2 learners’ collocational while taking ...

Automatic acquisition of raw source material is of great aid for the compilation of dictionaries, and, in particular, of specialized dictionaries such as collocation dictionaries. The extraction of collocations from corpora has been actively worked on since the late eighties. The quality of the state-of-the-art extraction algorithms allows the lexicographers to obtain lists of collocations they...
