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 ...

Differential-algebraic equations with higher index give rise to essentially ill-posed problems. Therefore, their numerical approximation requires special care. In the present paper, we state the notion of ill-posedness for linear differential-algebraic equations more precisely. Based on this property, we construct a regularization procedure using a least-squares collocation approach by discreti...

Explicit pre/post conditioning of the large, sparse and non-symmetric system of equations, arising from the discretization of the Dirichlet Poisson’s Boundary Value Problem (BVP) by the Hermite Collocation method is the problem considered herein. Using the 2-cyclic (red-black) structure of the Collocation coefficient matrix, we investigate the eigenvalue distribution of its preconditioned analo...

For teaching of collocations no resource exists that comprehensively ranks collocations in terms of usefulness for learners. Towards developing a method to produce such a resource, we define a collocation's utility in terms of its unpredictability; the inability of a student to derive the meaning of the collocation from her semantic knowledge of its constituent words. We conduct an experiment c...

there are no known studies that have been conducted focusing on the congruency or discrepancy of pre service agricultural education programmes in relation to secondary school agriculture teaching in zimbabwe. the purpose of this study was therefore to make a qualitative investigation on the contribution of pre service agricultural education training programmes to the teaching of high school agr...

A readability measure that can reliably estimate the difficulty level of sample texts has great potential in ESL teaching. We argue for the inclusion of collocation frequency as a generic factor in estimates of ESL text readability, since the readability of any text will be affected adversely by the presence of collocations. Collocational word combinations are seldom amenable to comprehension s...

Although traditionally seen as a languageindependent task, collocation extraction relies nowadays more and more on the linguistic preprocessing of texts (e.g., lemmatization, POS tagging, chunking or parsing) prior to the application of statistical measures. This paper provides a language-oriented review of the existing extraction work. It points out several language-specific issues related to ...

This paper describes a corpus-based contrastive study of collocation in English and Chinese. In light of the corpus-based approach to identify functionally equivalent units, the present paper attempts to identify the collocational translation equivalents of zunshou by using a parallel corpus and two comparable corpora. This study shows that more often than not, we can find in English more than ...
