Collocation is a common language phenomenon which has attracted the interest of researchers in many subfields of both theoretical and computational linguistics. Although there is no commonly accepted and precise definition of this phenomenon, collocations are generally understood as complex lexical items, often characterized as unpredictable, idiosyncratic, holistic, mutually selective, and so ...

BACKGROUND It has been shown that large interdisciplinary teams working across geography are more likely to be impactful. We asked whether the physical proximity of collaborators remained a strong predictor of the scientific impact of their research as measured by citations of the resulting publications. METHODOLOGY/PRINCIPAL FINDINGS Articles published by Harvard investigators from 1993 to 2...

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...

Corpus-based automatic extraction of collocations is typically carried out employing some statistic indicating concurrency in order to identify words that co-occur more often than expected by chance. In this paper we are concerned with some typical measures such as the t-score, Pearson’s χ-square test, log-likelihood ratio, pointwise mutual information and a novel information theoretic measure,...

Our main aim is the accurate computation of a large number of specified eigenvalues and eigenvectors of Mathieu’s system as a multiparameter eigenvalue problem (MEP). The reduced wave equation, for small deflections, is solved directly without approximations introduced by the classical Mathieu functions. We show how for moderate values of the cut-off collocation parameter the QR algorithm and t...

A finite-element approach, based on cubic B-spline collocation, is presented for the numerical solution of Troesch’s problem. The method is used on both a uniform mesh and a piecewise-uniform Shishkin mesh, depending on the magnitude of the eigenvalues. This is due to the existence of a boundary layer at the right endpoint of the domain for relatively large eigenvalues. The problem is also solv...

Crayton Walker,

A number of authors (Lewis 1993, 1997, 2000, Woolard 2001, Thornbury 2002) writing for English language teachers have argued that collocations are arbitrary and therefore there is no point in attempting to explain them to foreign language learners in the classroom. It is my impression that these writers have been very influential with the result that this view of collocation is firmly entrenche...

In this paper we start to explore two-part collocation extraction association measures that do not estimate expected probabilities on the basis of the independence assumption. We propose two new measures based upon the well-known measures of mutual information and pointwise mutual information. Expected probabilities are derived from automatically trained Aggregate Markov Models. On three colloc...

This paper focuses on the use of advanced techniques of text analysis as support for collocation extraction. A hybrid system is presented that combines statistical methods and multilingual parsing for detecting accurate collocational information from English, French, Spanish and Italian corpora. The advantage of relying on full parsing over using a traditional window method (which ignores the s...
