Collocations in the sense of idiosyncratic binary lexical co-occurrences are one of the biggest challenges for any language learner. Even advanced learners make collocation mistakes in that they literally translate collocation elements from their native tongue, create new words as collocation elements, choose a wrong subcategorization for one of the elements, etc. Therefore, automatic collocati...

Dissertation Abstract comprise words for which neither word can be substituted by a synonym or hyponym. Potential colloca-tions comprising certain adjacent part-of-speech tags are extracted from text. An online thesaurus and a lexical database of word classes are queried for synonyms and hypo nyms, respectively, for each potential collocation. These queries create potential challenger pairs, su...

In this paper a new method for solving (non-linear) ordinary differential equations is proposed. The method is based on finite elements (collocation method) as well as on genetic algorithms. The method seems to have some advantages in comparison with the typical sequential (one – step and multi – step) methods. Key-Words: Ordinary Differential Equations, Finite Elements, Genetic Algorithms, Evo...

to investigate the effect of massed and distributed collaborative and non-collaborative presentation on l2 learners’ comprehension and production of lexical collocations, 105 participants at takestan islamic azad university in 4 groups were assigned to four different treatment conditions (collaborative-massed; collaborative-distributed; noncollaborative-massed; and noncollaborative-distributed ...

Arbitrary recurrent word combinations (collocations) are a key in language learning. However, even advanced students have difficulties when using them. Efficient collocation aiding tools would be of great help. Still, existing “collocation checkers” still struggle to offer corrections to miscollocations. They attempt to correct without making any distinction between the different types of error...

This paper describes a characters-based Chinese collocation system and discusses the advantages of it over a traditiolml word-based systcm. Since wordbreaks are not conventionally marked in Chinese text corpora, a character-based collocation system has the dual advantages of avoiding pre-proccssing distortion and directly accessing sub-lexical information. Furthermore, word-based collocational ...

There are a large number of near-synonyms in English, differentiating these words have always been one the major difficulties English learning. The participation corpus provides new approach to identification near-synonyms.Based on Corpus Contemporary American (COCA), this study identifies Road and Street, group terms register, collocation semantic rhyme, results show that main difference betwe...

Lexical chunks have in recent years become widely recognized as a crucial aspect of second language competence. We address two major sorts of challenge that chunks pose for lexicography and describe computational approaches to addressing these challenges. The first challenge is lexical knowledge discovery, that is, the need to uncover which strings of words constitute chunks worthy of learners’...

Collocation has been considered a problematic area for L2 learners. Various studies have been conducted to investigate native speakers‘ (NS) and non-native speakers‘ (NNS) use of different types of collocations (e.g., Durrant and Schmitt, 2009; Laufer and Waldman, 2011).These studies have indicated that, unlike NS, NNS rely on a limited set of collocations and tend to overuse them. This raises ...

Abstract The present study explores the impact of corpus-based collocation instruction on intermediate Iranian EFL learners' writing ability. For this study, 84 Iranian learners, studying English as a foreign language in Bayan Institute, Iran, were selected and were randomly divided into two groups, experimental and control. Conventional methods of writing instruction were taught to the control...
